from CP Zilliacius:
In Sweden they could say “We do urban freeways right!”
The Southern Link motorway, part of a fairly tight circumference “beltway” around Stockholm, opened some years ago.
The western side (mostly not underground, extremely busy) has been open for decades.
Now they are building the Northern Link (the Eastern Link is left, and that’s in planning and preliminary engineering).
