The Tappan Zee Bridge is 3.1 miles long.
The existing Governor Malcolm Wilson Tappan Zee toll bridge, usually referred to as Tappan Zee Bridge opened to traffic in 1955 and is an integral component of the regional roadway network that connects South Nyack in Rockland County with Tarrytown in Westchester County in the Lower Hudson Valley.
The total length of the bridge and approaches is 16,013 feet (4,881 m). The cantilever span is 1,212 feet (369 m) providing a maximum clearance of 138 feet (42 m) over the water. The bridge is about 25 miles (40 km) north of midtown Manhattan.
It was designed to carry 100,000 vehicles on a peak day but traffic volumes have grown to approximately 138,000 vehicles per day with a high percentage being intrastate and interstate trucking.
In latest buzz, a large crane being used to construct the new Tappan Zee Bridge collapsed Tuesday, blocking all lanes for hours on the span it is replacing, closing the traffic artery for hours and injuring four people.
Most lanes were open for the Wednesday morning commute, but transportation officials were warning drivers to plan for extra delays after the boom of the crane toppled over into traffic Tuesday. Read more at NBC New York.
