In Kips Bay, the FDR Drive is located on a viaduct between 30th and 37th Streets. The southbound and northbound roadways rise onto a viaduct separately between 28th and 30th Streets; the southbound roadway ascends onto the viaduct at 28th Street, followed by the northbound roadway at 30th Street, and the two roadways merge into a single structure at 32nd Street. At this point, there is a two-lane shoulder on the left side of the northbound roadway, with one of the lanes cordoned off by a short concrete barrier. There is a provision for a southbound exit and northbound entrance at 30th Street, which was built in 1967 and would have connected to the Mid-Manhattan Expressway. However, after plans for the expressway were abandoned, this exit was never used, largely because there was already an exit four blocks north, at 34th Street. The unused exit was then blocked with a semi-permanent concrete barricade.
