Tappan Zee Bridge

The Tappan Zee Bridge is a cantilever bridge in New York over the Hudson River at its widest point, the Tappan Zee. It connects Nyack in Rockland County with Tarrytown in Westchester County. Construction started in 1952 and it was opened for traffic in 1955. The total length of the bridge and approaches is 16013 feet (just over 3 miles, about 4.9 km). The cantilever span is 2416 feet (736 meters) providing a 138 foot (42 meter) clearance over the water.

The bridge is part of the New York Thruway highway system, designated as Interstate 87 and Interstate 287. The span carries seven lanes of automotive traffic, with the center lane being switchable between eastbound and westbound traffic depending on the prevalent commuter direction. This is accomplished via a movable center barrier.

Eastbound traffic is subject to a toll of $3.
