How Battery Park City Authority Increased Costs of West Side Highway Tunnel

  

Textbook 101 case study of the elites' disrespect for civil infrastructure planning and design.



 

People opposed Robert Moses idea of modernizing the elevated West Side Highway.

 

People demanded a tunnel expressway replacement, within new rectangular box tunnels buried along the shoreline.  The World Trade Center project created an enormous amount of excavated material.  Hence its logical use for the initial phase of a planned landfill extension of western shoreline of Manhattan Island, south of 29th Street.  The tunnel would thus use the innermost strip of this new landfill.

 


 


Here are the initial planning, from the 1966 Lower Manhattan Study, showing this new rectangular box tunnel within the innermost portion of its new WTC-BPC landfill, before turning inland to parallel the existing bulkhead.

 

 


 


 



 


 

 

Note the improved geometry for the West Side Highway link with the Brooklyn Battery Tunnel.

 

Note the space of the new landfill used for the new expressway tunnel, that bypasses West Street, avoiding a need to excavate while maintaining Brooklyn Battery Tunnel approach traffic.



 

Battery Park City Authority, established 1968 dictates ban on using any part if its landfill for expressway tunnel, mandating its relocation to within West Street- thus requiring an excavation with potential underground utility matters, while denying the improved geometry for the ramps into the Brooklyn Battery Tunnel.

 

Such an excavation, together with the issues of underground utilities, made the southernmost portion of the future underground WSH more expensive to construct.  How much?  $300 million?  $600 million? $850 million?  Strange how we saw so little attention to this.


Where was any protest movement against the plans for the World Financial Center, and the other B.P.C. buildings facing inland?  Any demands to modify the plans to shift the eastern facing building line west to preserve the underground easement for a future West Side Highway Tunnel


 The 1974-1985 Westway project would be routinely bashed by supposed "fiscal conservatives" out to block wasteful government spending.

 

So, at anytime from 1968 onwards, where were the great protests about the BPCA blocking the use of its innermost landfill, by the multitude of "fiscal conservatives" that we subsequently saw bash the Westway project?

Hartford 400 Plan

 

 

New revised plan for restructuring-reconstructing the Hartford, Connecticut  expressway system, with cut and cover tunnels for existing and for new expressway segments, the deletion of the huge array of expressway links with the establishment of a new east to west urban boulevard.

N.Y. Requires Brooklyn-Queens Expressway Reconstruction

 

To this very day, N.Y.'s "leaders" wallow in circles over what to do about the B.Q.E.?

 

The B.Q.E. was originally built during the 1940s.  Its recent project to replace its Kosciusko Bridge upped capacity from 6 to almost 10 lanes.  Yet nothing has yet been done to reconstruct anything to the south.  Nothing about the overloaded segment from the Long Island Expressway to the Williamsburg Bridge.  And only discussion about its two other segments to the south, namely the portion with the other bridge into Manhattan connections (that includes the architecturally magnificent triple deck cantilever.), and its southernmost segment known as the Gowanus Expressway.

 

In 1997, the once highly respectable Regional Plan Association spotlights the idea of a Gowanus Expressway Tunnel, to replace its  viaduct - with tunnel- seen as cut and cover flanking the existing expressway viaduct,, so featured at a panel at their April 1997 one day conference.


Simultaneously, an architect announce the idea of what is now called the Cross Downtown Brooklyn Tunnel: a straight line tunnel to depart and reconnect with the BQE.  This would create a perpetual benefit of a significant time savings for through traffic not destined to the bridges to Manhattan.  And it would siphon such traffic to allow re-striping from 3 to 2 through lanes per direction through the cantilever.

 



NYSDOT subsequently issued a study of  the Gowanus Expressway Tunnel, presenting a variety of route options, though without the straight line tunnel.

The Gowanus Expressway study has been supplemented with a study about its connecting BQE segment north.  

 

The Cross Downtown Brooklyn (CDB) Tunnel would supplement the existing B.Q.E., which is retained as a collector distributor system, and re-striped from 3 to 2 lanes per direction. 

 

It is the sole tunnel option that adheres to the concept of the shortest link being a straight line.  Nonetheless, this subsequent study report includes it with other alternative tunnel routes, all of which are considerably lengthier (more expensive) while not providing the time savings advantage.

 

 

 

 The tunnel route alternatives so studied are:


1. T-1 running under downtown Brooklyn by Henry Street
2. W-1, a variation of T-1 also running under downtown Brooklyn but further west by Hicks Street
3. T-2 following the existing BQE corridor alignment
4. T-3 outboard tunnel following an alignment similar to the existing BQE but further west and into the river.
5. W-2 straight line tunnel between Exit 24 of the BQE (by Prospect Expressway) and Exit 30 of the BQE to the East of Washington Avenue
6. W-3 outboard tunnel between Sunset Park and Exit 33 (only qualitative study based on length)
7. W-4, a variation of W-2 between Exits 24 and 30 that extends further south than Prospect Street where it joins a Gowanus tunnel alternative that follows the bulkhead.

 

W2 straight line tunnel to the northern end of the existing Gowanus Viaduct, and W4, a variant of W2 extending further south to a Gowanus Tunnel along the bulkhead.


 

 

W2 and W4 are to be moled tunnels via TBMs, as they must to the north to pass fully beneath the street grid.


The study enumerates several variants of TBM highway tunnels, with either 2 or 3 travel lanes per roadways with 2 foot left and 4 foot right shoulders:

 

1) Single 66 foot diameter, stacked 3 lane roadways

2) Duel 55 foot diameter, single 3 lane roadways

3) Duel 42 foot diameter single 2 lane roadways

4) Single 54 foot diameter, stacked 2 lane roadways

 

These TBM tunnels are shown with 2 foot left and 4 foot right shoulders.  This is akin to the recently constructed Seattle Route 99 Highway Tunnel.



As a heavily used interstate highway, and as all new construction, should this several mile long I-278 Cross Downtown Brooklyn Tunnel be so narrow with its lack of sufficient shoulder space?  Imagine the traffic and situations of stalled vehicles in need of service or a tow, and consider the servicemen.  Would we want that with a meagerly 4 foot right shoulder?  Or 6 or 8 feet?


At a minimum, lets provide full 12 foot wide right shoulders.

 

The authorities prefer a single tunnel bore with stacked, 2 level roadways, as more economic.  With the available 57 foot diameter TBMs as used in Seattle Route 99, this gives too little in safe shoulder space, and hence a somewhat larger bore less, but less than 66 feet..

 

With the matter of potential EV battery-pack fires, particularly larger vehicles as trucks, we should go with the costlier option of TWO tunnel bores, to avoid stacking one direction atop another.  With the already available 57 foot diameter TBMs, duel tunnel bores would each have a sufficiently wide roadway of a pair of travel lanes with a 12 foot right, and 6 foot left shoulders.

 

So far, instead of any outcry to provide adequate shoulders, we get the typical post 1963 cacaphony of budget conservatives insisting upon deflecting for the early 1980s elimination of the NYSE stock transfer tax (from a modest 0.1% to effectively 0% with NY Governor Hugh Carey's 1978 legislation to institute a "rebate" (refund) of that tax revenue.  That highways are evil.  That we must view them with disdain and hostility, and hence, that we must remain ignominiously on the matters pertaining to their DESIGN.

 

We are told to de-map the urban expressways. and change them into surface streets, screw everyone.  Eliminate a grade separated road outright, and fail to even consider the variables of where the traffic would instead, including even the measurable impacts of heavy streams of vehicular traffic.  Sure an urban expressway is going to centralize vehicular emissions due to the volumes.  But is it better to leave everything as is, or to somehow convert an expressway to a boulevard with traffic lights, or is it to modernize and enclose that traffic stream within a new urban expressway tunnel equipped with pollution filtration technologies?

 

So far the plan has not yet been set.

 

Its physical realities are that it must be constructed together to the south with the Gowanus Expressway Tunnel, as well as to the north to cut and cover reconstruction of the BQE trench segment alongside and south of the ramps with the Williamsburg Bridge.

 

Other factors to be determined include what to do about the BQE trench, as well as its elevated segment.

Westway & Wall Street

 

Beachway

 

 

Westway - the 1974-1985 West Side Highway Replacement Project - was to be the modern replacement for the antiquated, obsolete design elevated West Side Highway along the southern western edge of Manhattan, designed and constructed during the 1920s or early 1930s.  It was to employ a northern extension of the landfill pictured above by the WTC.  The anti Westway people, being anti park and supposedly anti development would sanction the loss of what would have been an incredible waterfront park (and potential fantastic place for political gathers), with the paving over of beachway with Batter Park City.

 

Westway reflected a dislike of elevated urban waterfront highways with its portion south of 29th Street placing the reconstructed West Side Highway within a new tunnel.  Urban waterfront elevated highways had become increasingly disfavored with San Francisco's controversial partially built Embarcadero Freeway, and a growing number of New Yorkers were not that keen on Robert Moses idea of modernizing/widening the existing WSH viaduct.  

 

So the mid-late 1960s planning envisioned for southernmost Manhattan (featuring the WTC & the landfill extension that became Battery Park City), included a new tunnel-box expressway within the new landfill at its inner edge next to the existing bulkhead.  This offered the least expensive way to make an expressway tunnel, for avoiding actual excavation under West Street/12th Avenue, and any utility conflicts, while providing better geometrical connections with the Brooklyn Battery Tunnel. 

 

Nevertheless, despite the cost and geometric benefits, this was to be overruled by a dictate to instead have the southernmost portion of the future new tunnel West Side Highway within West Street, and to have it as an open trench, so extending north past the WTC, before transitioning to a tunnel swinging out into the new landfill at a diagonal beneath new park recreational facilities - nicely designed, but for that this cut across the location of Pier 34 where Titanic had been scheduled to appear, and continuing north with this tunnel beneath the new landfill's new shore line, with a pedestrian promenade, and new residential development upon the one block extensions of the streets into the Hudson.  North of 29th Street, Westway was entirely elevated, as were its connections with the Holland and Lincoln Tunnels.  Westway, which was to be an interstate highway I-487, would have simply connected with the Henry Hudson Parkway at 57-72nd Street, thereby failing to offer a continuous interstate highway to the north connecting with I-95 or I-87.

 


 


Westway's 1974 unveiling was met with an opposition, well crafted to deny the benefits, to deflect any substantive criticisms, e.g. rescind the dictate against using the new landfill for the buried expressway south of Vesey Street, reconfigure it to preserve Pier 34, and even extend the tunnel further north.

 

Central to this anti Westway movement was that it was somehow too expensive, with unsubstantiated claims that it would have enormous cost overruns. that defy any credibility. 

 

"The initial conception was estimated to cost between and $1 and $2 billion, with 90 percent paid for by federal dollars once it was added to the interstate system.  Soon the project's official estimate solidified at slightly over $2 billion.  Even at these quite conservative cost estimates, supporters, detractors, and reporters all agreed with one basic reality about Westway: it would be the most expensive highway ever built in the United States.  Its actual cost would likely have reached in the $4-7 billion range but could have soared far higher.  Looking back and comparing Westway and other large scale mega projects such as Boston's "Big Dig", which involved only two miles of tunnel, and escalated in cost from $4 billion to approximately $15 billion, a prominent Westway advocate  (speaking not for attribution) estimated that Westway would have cost in the tens of billions, perhaps as much as $30 billion when completed.  Others, like Craig Whitaker, think Westway's plan avoided engineering complexities that would have caused such skyrocketing costs." p 16 Fighting Westway- Envirnmental Law, Citizen Activism, and the Regulatory War that Transformed New York City, William W. Buzbee

 

Indeed, as the Boston Big Dig was an incredibly more complicated construction project.  It involved constructing a new 10 lane (5/5) tunnel beneath the existing 6 lane I-93 viaduct (while maintaining traffic), while constructing a tunnel extension of east-west I-90 via jacked box tunnel through  molasses soil condition.  Westway in sharp contrast was constructing a rectangular box tunnel cut and cover tunnel within new landfill, free of the complication of working around existing infrastructure.

 

Coupled with such fear mongering about construction costs were a pair of pretenses, A)  that the US/NY was somehow too poor to afford world class infrastructure, by obsessing that urban expressway projects must be outright cancelled to siphon the construction funds towards "transit" even without any express guarantee of a particular transit project, nor cost analysis of failing to preserve easements from ill placed costlier real estate development; and B) Westway was particularly bad for its use of tunnels, as if placing the stream of vehicular traffic underground is somehow evil. 

 

SO, we saw a law suit upon Clean Air Act allegations because of the pollution "hot spots" within a ten foot or so area of the tunnel portals (embarrassing to petroleum industry), rather the traffic should be without any tunnel (in conformity to that industry's maxim that the solution to pollution is dilution), along with the crafted outcry that N.Y. and the U.S. was somehow too poor to afford Westway.  Of course they must propagandize in favor of cheapness- that we had to cancel Westway outright, and dare not replace it with any other tunnel facility (more petroleum industry opposition).

 

The "clean air" suit failed, whereas a subsequent suit about inadequate data gathering regarding the landfills displacement of the area where they laid their eggs near a sewer outlet.  The authorities respond with a remarkable timidity- the stripped bass issue was a red herring as they could have simply gathered greater data, and used it for a hatchery relocation, e.g. sinking a few rail cars. Yet not only do they surrender, September 1985, they refuse to offer any subsequent plans for a modern under ground West Side Highway replacement.  Or even a fully continuous freeway, let alone anything enclosed in tunnel.

 

The anti Westway movement exploited popular sentiments/concerns to stop the project, but not otherwise. People opposed Westway for a variety of reasons, preserving the piers, scaling down development, or improving park pedestrian access, which the formal Westway opposition was carefully crafted.

 

Yet where was any movement to save pier 34?

 

Yet where was this opposition to development to the south with BPC, and create a grand new beach front park?


And why this sentiment that the US/NY was too poor to have a modern tunnel WSH?


The sort of opposition crafted against Westway is best summed up in this NYT op ed piece by Marcy Benstock:


https://www.nytimes.com/1981/06/30/opinion/for-a-westway-trade-in-by-marcy-benstock.html

 

Mayor Koch says he may decide by Nov. 15 whether or not to return to his pre-mayoral-election position in favor of trading in Westway for more than $1.7 billion for mass transit and an alternate road. A decision in favor of a trade-in would be the single most significant step that could be taken to reverse the terrible decline in New York City's transit service.

 

The excuse for depriving mass transit of these desperately needed funds has been that the trade-in is risky while Westway funding is certain. But with the Highway Trust Fund in the red this year for the first time ever, the risk that the Westway superhighway and landfill would take decades to build and might never be finished is greater than any uncertainties with trade-in.

 

Eighteen cities in 15 states would not have opted for trade-in if it didn't work, and they make up a national constituency for improving the trade-in program further. As soon as the Secretary of Transportation approved a Westway trade-in request - no trade-in request has ever been denied - the city would become legally entitled to the full 90 percent Federal share of the Westway cost estimate approved by Congress in 1979 ($1.5 billion plus a quarterly adjustment for inflation). Only the rate at which the funds came in would be affected by annual appropriations. Until fiscal 1979, Congress appropriated more each year than trade-in cities were ready to spend. In fiscal 1980, the $700 million trade-in appropriation plus the $250 million left over from prior years funded 80 percent of the $1.2 billion requested across the country.

 

But severe new problems with highway funding are slowing the rate at which new interstate highways can be financed. Westway's exorbitant $2.3 billion cost (of which Congress has agreed to pay only $1.5 billion) and its complex design, and the history of projects such as the much-delayed Bruckner Expressway, make it unlikely that Westway could be finished in this century.

 

The Highway Trust Fund is in trouble because inflation is adding greatly to highway construction costs at the very time when Fund revenues, based largely on the 4-cent-a-gallon gasoline tax, are declining. Congressional efforts to raise the tax this year failed; pressure is already being exerted to allocate any gas tax increase to such other underfunded programs as Social Security, mass transit, solar energy, and rehabilitation of existing roads.

 

''Interstate completion, in dollar terms, is an unattainable goal,'' according to a June 1980 Federal Highway Administration report. ''Assuming 7 percent annual inflation, current Interstate authorizations through 1990, including the unobligated (Trust Fund) balance as of December 31, 1979, could meet only $30.1 billion of the remaining ($50.75 billion) costs.''

 

New York State's share of that $30.1 billion national total for the next 10 years is unlikely to be more than 5 percent. (Its share of the $3.5 billion interstate apportionment for fiscal 1981 is 4.3 percent.) But 5 percent of $30.1 billion is only $1.5 billion for the entire state for the next 10 years - not enough to finish building Westway, even if the state's entire interstate apportionment were used for that purpose and not a penny went to other interstate projects elsewhere in the the state.

 

If, as seems more realistic, Westway received an average of $100 million a year of the state's average $150 million apportionment, it would take nearly 21 years to cover the 90 percent Federal share of Westway's $2.329 billion cost. Any cost overruns would drag out the construction period still longer.

 

However, in an era of shrinking budgets and growing energy shortages, Congress may have no choice before then but to halt the funding of unneeded highways. In that case, all the city would have to show for years of disruption would be a partly completed landfill in the Hudson River oozing sewage sludge dredged from the bottom, and a transit system in ruins.

 

How much better it would be if Mayor Koch brought the longstanding Westway controversy to a swift resolution with all-out support for a trade-in. An alternate road could then be finished in three years for 5 percent of Westway's cost. The revitalized waterfront that has already begun to emerge despite the inhibiting effect of Westway could be enjoyed by New Yorkers for their lifetimes. Development could go forward on the largely empty 91-acre Battery Park City landfill.

 

Jobs in mass transit and West Side industries would be saved, and new ones created in transit rehabilitation. The one-shot $100 million Westway right-of-way payment the city might have gotten in return for ceding its priceless waterfront to the state would be more than compensated by the recurring revenues and savings that a tradein would generate in mass transit, pier leases, payroll and property taxes, and city services. Most important, the largest, surest untapped source of transportation capital in sight could begin to be used where it is needed most: to prevent the physical and financial collapse of the transit system and make it fit for human beings again. --------------------------------------------------------------------- Marcy Benstock is director of the New York City Clean Air Campaign.



Marcy Benstock makes zero mention of the effective elimination of the NYSE stock transfer tax!

 

Whereas retail sales tax is 7%, the NYSE sales /transfer) tax was a mere 0.1%.  That is until the late 1970s/early 1980s, with 1978 NYS legislation to "rebate" - e.g. refund - the 0.1% tax funds 100% by the early 1980s.  As this was done just prior to the NYSE trading becoming computerized, making feasible the practice of HIGH FREQUENCY TRADING.  I am sure that anyone who is a Harvard educated graduate can see the potential ramifications fiscally.

 

Yet where were you, or any of the other participants of the anti Westway/anti any world class underground replacement for the antiquated West Side Highway viaduct, on this impending change in the tax codes to facilitate HIGH FREQUENCY TRADING, while touting the line that Westway was somehow "too expensive"?

 

The Westway tunnel in fact is the cheapest way to construct a highway tunnel, for being within new landfill (instead of an excavation of 12th Avenue/West Street with the matters of underground utilities).

 

The Westway landfill was also good in the fashion of that which was created with the excavation material from the WTC construction, insofar as providing new land.

 

Yet the Westway landfill was bad insofar as displacing southwestern Manhattan's historic pier district, but where were any protests about that landfill further south.

 

Westway's development would be viewed negatively, never-mind that its new residential establishment would be more of an extension of Manhattan, rather than an urban enclave as BPC- which contrary to the negativity against Westway related development, gets the free pass endorsement of Ms. Benstock in the NY Times.  Why would not Benstock have instead, started a new campaign after Westway's September 1985 defeat, to block construction of Battery Park City (or at least scale it back), to create a new park?  A park that would have been the best site for public gatherings, indeed even potentially a camp out for such a group as Occupy Wall Street!  And how about the matter of Pier 34- Titanic's scheduled berth?  Surely people wanted to see it saved, yet where was Benstock or any of the other figures of the Westway opposition with preserving Titanic's scheduled arrival pier?

 

As did the Village Voice supposed "avant gard" approbation against Westway, as if placing an established expressway corridor traffic stream all upon the surface with traffic light were better than an expressway tunnel, with a surface boulevard more suited to local traffic/pedestrians. 

 

The NYSE got its 100% rebate of its minuscule rate 0.1% stock sales/transfer tax, at the cusp of its computerization, surrendering the economy to High Frequency Trading, while people in general fell for the con that Westway was somehow unaffordable, while saying nothing about the impeding NYSE trading transfer/sales tax exemption, nor its combination with trading computerization.

Yonkers, N.Y. Hudson River Bridge/Northern Metro Regional Bypass

 

The George Washington Bridge NEEDS alternative routes- the NYC Metro Area must have additional trans Hudson River crossings.  Northwards to the Tappan Zee Bridge, Yonkers is the best, for connecting with the existing east-west Cross County Parkway- a freeway reconstructed during the 1960s, 1970s and early 1980s that excludes trucks.


Yonkers, NY authorities appear to suggest the preferred site, marked by the naming of "Bridge Street" at the east west axis of Ludlow Streets, where it would land, with its approach eastwards into a hill by Route 9, where the highway would continue within tunnel, with connections to and from the north to the Cross County Parkway.

 

Extend that Yonkers, Ludlow Street axis to New Jersey, where it would land.  It would have connections with the Palisades Parkway.  And it must have a minimum of 6 lane mainline continuing west, as simply linking to the Palisades Parkway is problematic given the lack of a continuous traffic light free link to I-95.  Years ago, 1940s-1950s, the Yonkers, N.Y. - Alpine, New Jersey bridge was proposed to have an all new freeway continuing west, which was not built.  Instead, have a tunnel that arcs southward to follow the Northern RR, to connect with I-95/I-80.  


The I-80/I-95 to bridge link would be via tunnel, cut and cover along the Northern Line., and then curved towards facing Yonkers, with portal by the Palisades Parkway.  Curved portion would be bored to avoid surface disruption, emerging just past Montammy Golf Club, at the Palisades Parkway, to the bridge to Yonkers, N.Y., along Ludlow Street.  A minimum 6 travel lane facility could be either a single tunnel with two levels, or a pair of single or two level tunnels.  Existing 57 foot diameter TBMs require a pair of tunnels, each with a single 3 lane roadway, with only about 6 feet of shoulder space, or a double level 2 lane roadway with the 6 foot shoulder space.  Larger tunnels, 62, 67, 72 feet diameter would be preferable, particularly for line of sight within tunnels that are curved.

 

In Yonkers, this moled land approach tunnel might be a short segment, that emerges to cross atop the Saw Mill River Parkway, elevated over the valley, before entering a second tunnel further east as the topography rises, that extends further east to cross I-87, the Raceway Park parking lot, and the Bronx River into the City of Mt. Vernon, transitioning to cut and cover tunnel along 2nd Street.

 

Or instead it could be continuous with the west Yonkers segment descending to pass beneath Saw Mill River.

 

In Mt. Vernon, this cut and cover tunnel follows 2nd Street before turning south along the old N.Y., Westchester & Boston RR corridor, and continuing in the Bronx alongside that same RR's currently extant Dyre Avenue IRT line, to connect to and from the south with I-95 via an augmented 222nd Street exit, extending to the Throggs Neck Bridge Expressway, and providing a valuable new traffic corridor for handling potential emergency situation evacuation traffic.

N.Y. MUST Build to Facilitate Long Island Evacuation

 

 

Imagine an emergency situation/mass evacuation from Long Island.

 

Imagine the traffic bottlenecks from the Throggs Neck Bridge onward, with traffic from Long Island funneled to the Cross Bronx, the Hutchinson River Parkway (HRP) and I-95.

 

Clearly we must have the I-287 Cross Sound Link connecting L.I. with Westchester County, best as a pair of over-water spans, with the shore approaches enclosed in tunnel, as well as offshore a minimum of 1100 feet.  This avoids the cost of a full miles long tunnel, while providing the mitigation of tunnel enclosure where needed the most.

 

Clearly we must have a southern NYC metro regional tier, of new tunnel expressways, consisting of an augmented Verazanno Narrows link, with new east-west link to the Conduit Avenue/JFK Belt corridor, beneath new linear parkspace, with new cut and cover expressway tunnel east to Sunrise Highway, as well as north to near Belmont Park, to a pair of tunnels along Hempstead Boulevard and 212nd Place as effectively the Clearview Expressway. extension.

 

Certainly we could use additional cross-water capacity, perhaps with a pair of 2 lane tunnels directly from Brooklyn to New Jersey, as well as another such set flanking the VNB.

 

Yet we not only lack the east-west mixed traffic link between New Jersey and southern Long Island, we are hampered by serious deficiencies for distributing vehicular traffic entering the mainland, made worse by I-95's lane drop from 8 to 6 lanes at its interchange with Pelham Parkway, as well as the roadway geometry of southbound I-95 immediately north of the HRP with the reduced line of sight issues caused by the design of the northbound left-hand off-ramp.  

 

We are already long overdue for a project to extend the outermost northbound I-95 lane at least to the  northbound HRP., and for improving the line of sight of southbound I-95 to the north,

 

Future needs call for a more expansive plan.

 

First, reconstruct the existing open trench and surface 8 lane I-95 between the Pelham Parkway and the split to the Throggs Neck Bridge, with a greater capacity cut and cover tunnel with exhaust filtration.trench, building outwards by excavating space under the adjacent parallel roads with added road space re-strip able for adding 2 lanes in each direction & wider shoulders, and with no lane drop before the off ramp to the northbound HRP.

 

Second, establish a new alternate route for traffic from Long Island, to divert traffic from I-95, of a new north-south expressway tunnel, splitting from I-95 at the current northbound lefthand East 222nd Street exit, and following the Dyre Avene IRT/NY, Westchester & "Boston" RR corridor into southern Westchester County, N.Y.  Such had been planned during the 1950s as a Central Corridor Expressway, though as a conventional, non tunneled design. Our 21st century design cut and cover (with brief open trench segments) would run alongside this RR in the Bronx, and into Westchester. 

 

Industrial area segments would include air rights replacement buildings for local businesses.

 

Project would be designed to accommodate a substituent restoration of the NY, Westchester & "Boston" with the elevated segment extending into Westchester restored, and with the expressway tunnel designed to facilitate reconstructing the RR viaduct and accommodating the restored RR trench, with the project including a replication of the demolished in 2016 East 6th Street NY&B, and the below street level station in Wykagyl in the North end of New Rochelle.

 

Further north, this cut and cover tunnel expressway tunnel would devote the surface to a linear park and allowing a subsequent restoration of the former NY, Westchester & Boston RR service with architecturally faithful stations so incorporated.  Have it divert to the west to preserve the architecturally monumental  Stratton Road "Quaker Ridge" station.  Would divert to follow Bryant Avenue within White Plains, NY to a reconstructed interchange with I-684.


And together with it, have a plan for it to include a new link extending westerly in Mt. Vernon, transitioning from cut and cover to moled tbm tunneling to pass into Yonkers beneath the Bronx River, Raceway Park, with connections to and from the north with I-87, and continuing west to emerge along Ludlow Street to a new Hudson River Bridge connecting Yonkers N.Y. and Alpine N.J., ideally with a tunnel link to I-95 just east the interchange with I-80
