Interstate 787 New York


Interstate 787 runs north along the Hudson River from I-87 (New York Thruway) and U.S. 9W (Southern Boulevard) through Albany, Menands and Watervliet. Turning east along side NY 7 at Green Island, I-787 spans the Hudson River on the Collar City Bridge into Troy. NY 787 spurs northward from the cloverleaf interchange with I-787 and NY 7 to the city of Cohoes.


Interstate 787 was planned as The Riverfront Route along the Hudson River in Albany during the early 1950s.1
