Who built the tappan zee bridge?

Answer 1

In the 1950's, because of the high demand of traffic traveling to upstate New York and causing major headaches and strain on the Hudson River Crossings such as the Holland Tunnel, Lincoln Tunnel, and George Washington Bridge, the Port Authority of New York and New Jersey created a plan for a bridge to cross the Hudson River further up the river but not so far that drivers could not reach New Jersey from its' connection. At the spot where it is now, north of Dobb's Ferry, New York, the PANYNJ however dropped the plan to create the bridge, but was picked up by New York governor Thomas Dewey and New Jersey governor Alfred Driscoll. The bridge was created with World War II military technology and by people who were in the military and/or had experience in working with such technological skills.

The original bridge still stands today, but because of the continued traffic that rides over the bridge daily, plenty of strain has been put on the aging bridge, making the New York State Department of Transportation create a proposal to create a new bridge which can hold more traffic than the original bridge has already held and stay up for longer than the "unsafe" original structure. Construction is set to begin in 2013 and targeted to end by 2017.
