Given that these two are almost right across the street from each other, they have been combined as one listing for the sake of convenience.

Along with the Bond Street Gap, this is the only street gap that is heavily skated throughout Manhattan. It doesn't have the same, high-curb to low-curb advantage as Bond Street does, extends about six-and-a-half, to seven feet from curb-to-curb, has ample smooth sidewalk runway, and a pretty good concrete landing. Just be aware of cars occasionally coming down/up the block.

Considering Downtown has close to no decent handrails that you don't get kicked out of, this very imperfect spot deserves mention. The rail itself is average handrail height, goes down six stairs and is about an inch and a half wide on top. The runway is absolutely perfect in every way: smoothness, length, no cracks, etc. The landing is the main problem though, considering you have only about ten feet to roll before you crash into a metal bar.

You'll get kicked out of neither one of these spots, and they are both pretty well lit at nighttime

The Gap is at the end of Exchange Place Alley on Church Street, right before the Brooklyn-Battery Tunnel. The rail is in the park across the street from the gap, on top of the overpass. Take the N or R to Rector Street and skate west on Church, you should run into the street gap within two or three blocks.
