Interstate 95 in New York

Interstate 95 (I-95) is part of the Interstate Highway System and runs from Miami, Florida, to the Canada–United States border near Houlton, Maine. In the US state of New York, I-95 extends 23.50 miles (37.82 km) from the George Washington Bridge in New York City to the Connecticut state line at Port Chester. The George Washington Bridge carries I-95 across the Hudson River from New Jersey into New York City. There, I-95 runs across Upper Manhattan on the Trans-Manhattan Expressway for 0.81 miles (1.30 km) through Washington Heights. It continues east across the Harlem River on the Alexander Hamilton Bridge and onto the Cross Bronx Expressway. In the Bronx, I-95 leaves the Cross Bronx at the Bruckner Interchange, joining the Bruckner Expressway to its end. North of the interchange with Pelham Parkway, it then continues northeast via the New England Thruway (which is part of the New York State Thruway system) out of New York City into Westchester County and to the Connecticut state line, where I-95 continues on the Connecticut Turnpike.

The Trans-Manhattan Expressway also carries US Route 1. Approximately 280,000 vehicles traverse the expressway on a daily average basis. Completed in 1960, the expressway is located below ground level, in an open cut; however, the George Washington Bridge Bus Station and the highrise Bridge Apartments are built over the expressway, creating intermittent tunnels. It is maintained by the Port Authority of New York and New Jersey (PANYNJ). Although the highway geographically runs east–west, it carries the north–south routings of I-95 and US 1. The westbound lanes carry the southbound designations of both routes, while the eastbound lanes carry the northbound designations.
