Construction on the Tappan Zee Bridge started in 1952, at the height of the Korean War. Because of a materials shortage during the war, the bridge was constructed cheaply and designed to last only 50 years. The Hudson River crossing has now been standing for 60, and the New York State Thruway Authority is considering designs for a replacement.

The above image is a rendering the likeliest candidate for the bridge’s redesign, which was recommended from a field of three candidates by a Cuomo-approved selection committee. It will likely cost somewhere between $3 and $4.5 billion, though the plan for financing it has not yet been released. The thruway committee will consider the proposals December 17, with hopes to finish construction by 2017.
