In New Jersey, the proposed I-287 had originally been designated as FAI Corridor 104 and incorporated what was planned as the Middlesex Freeway. The New York State Thruway portion of I-287, which included a crossing of the Hudson River, opened in 1955. The Cross-Westchester Expressway, which was originally designated as Interstate 187 ( I-187), opened in 1960 as Interstate 487 ( I-487) before later becoming part of I-287. Within New Jersey, I-287 is maintained by the New Jersey Department of Transportation (NJDOT), and, within New York, it is maintained by the New York State Thruway Authority (NYSTA).Ī bypass around New York City had been planned since the 1950s and would become a part of the Interstate Highway System and receive the I-287 designation. After crossing the Hudson River on the Tappan Zee Bridge, I-287 splits from I-87 near Tarrytown and continues east through Westchester County on the Cross-Westchester Expressway until it reaches the New England Thruway. After crossing into New York at Suffern, I-287 turns east on the New York State Thruway ( I-87) and runs through Rockland County. The northernmost part of I-287 in New Jersey passes through mountainous surroundings. In Bridgewater Township, the freeway takes a more northeasterly course, paralleled by US Route 202 (US 202). Through New Jersey, I-287 runs west from its southern terminus in Edison through suburban areas.

I-287, which is signed north–south in New Jersey and east–west in New York, follows a roughly horseshoe-shaped route from the New Jersey Turnpike ( I-95) in Edison, New Jersey, clockwise to the New England Thruway ( I-95) in Rye, New York, for 98.72 miles (158.87 km). It is a partial beltway around New York City, serving the northern half of New Jersey and the counties of Rockland and Westchester in New York. Interstate 287 ( I-287) is an auxiliary Interstate Highway in the US states of New Jersey and New York. NJ: Middlesex, Somerset, Morris, Passaic, Bergen
