Interstate 287 encircles the greater New York City area along a 67.54-mile route in New Jersey and 31.18-mile alignment through New York state. The freeway shares 19.20 miles with its parent along the New York Thruway, joining the north end of the Garden State portion with the Cross West Chester Expressway east of the Tappen Zee Bridge.

Beginning at the transition of New Jersey 440 south over the New Jersey Turnpike (I-95) at Edison Township, I-287 leads west to Metuchen, South Plainfield and Piscataway Township. A portion of this stretch was originally slated as Interstate 95, meant to link the route between the NJ Turnpike mainline and the proposed Somerset Freeway alignment southwest to Trenton. I-95 was formally dropped from this alignment in 1982 when the Somerset Freeway was cancelled.1

Beginning its northern turn, Interstate 287 winds around Bound Brook to Somerville, commingling with both U.S. 202 and 206 north to Pluckemin and Bedminster Township. A dual roadway configuration on this stretch separates through traffic from movements with Interstate 78. I-287 was completed north from Edison to U.S. 202 & 206 (Exit 22) in 1964.1

Climbing onto Second Watchung Mountain at Far Hills, Interstate 287 starts the eastern movement toward New York. I-287 winds through Bernards Township to Morristown, Hanover Township and Parsippany, where it meets Interstate 80. From 1973 to November 1993,1 the freeway ended just north of I-80 in Boonton (Exit 44 / U.S. 202).

The final stretch takes I-287 through Montville Township along Waughaw Mountain to Riverdale, Wanaque and another climb through the southern Ramapo Mountains. There the route turns more eastward again, straddling the hillside of Campgraw Mountain through Franklin Lakes to Mahwah Township and an exit of the state at Houvenkopf Mountain. Completion of I-287 took place in August 1994, when the interchange with the New York Thruway (I-87) was upgraded to incorporate high-speed ramps.1
