The Belt Pkwy eastbound, takes a sudden lurch to the north
at Sunrise Hwy, passing beneath the southern branch of the Long
Island Railroad.
It emerges on the other side as the Laurelton Pkwy. The Laurelton
was actually just as much the Belt, as the Belt. The part of the
Belt known as "The Belt", running west from here to
the Gowanus Expwy in Brooklyn, was actually subnamed Shore Pkwy.
Along with the Laurelton, Cross Island and the pre-expressway
Gowanus, these individual parkways made up the Belt system, originally
planned as a Circumferential network to ring Brooklyn & Queens.
Somehow, everyone got used to considering the Shore section as
thee Belt. Apparently, the city has long ago given up on trying
to keep the Shore name alive. Although you'll see it on maps,
all signs pointing to it, refer to it as the Belt.
