Interstate 690

Interstate 690 (I-690) is an auxiliary Interstate Highway that extends for 14.19 miles (22.84 km) through the vicinity of Syracuse, New York, in the United States. It is a spur of I-90 (here part of the New York State Thruway) that travels southeast from Thruway exit 39 in Van Buren to I-481 in DeWitt. In between, I-690 passes through the western suburbs of Syracuse before heading east through the city itself, where it meets I-81 in downtown Syracuse. The expressway continues northwest of the Thruway as New York State Route 690 (NY 690).

Route description

I-690 begins at a double trumpet interchange with the New York State Thruway (I-90) in the town of Van Buren. The six-lane, fully shouldered limited-access highway continues north toward Baldwinsville as NY 690 while I-690 travels east from the junction. Even though I-690 continues north of the Thruway as NY 690, the numbering system on I-690 does not continue with the route. The interchange with the Thruway is labeled as exit 1, leaving exits on NY 690 without numbers. Additionally, NY 690 is signed north–south while I-690 is signed east–west. Before physically crossing I-90, it features a partial interchange with John Glenn Boulevard, and turns southeast.
