The collapse of Minnesota's I-35W Mississippi River bridge in 2007 raised worries about the Tappan Zee Bridge's structural integrity. The deteriorating structure bore an average of 140,000 vehicles per day, substantially more traffic than its designed capacity. During its first decade, the bridge carried fewer than 40,000 vehicles per day.īy the 2000s, the old Tappan Zee Bridge was "decaying" and "overburdened". Built immediately after the Korean War, the bridge had a low construction budget of only $81 million and a designed life-span of only 50 years. It was the longest bridge in New York State, at a length of 16,013 قدم (4,881 م) including approaches. The bridge was 3 ميلs (4.8 kم) long and spanned the Hudson at its second-widest point. The original Tappan Zee Bridge was a cantilever bridge built from 1952 to 1955. The Tappan Zee Bridge is the only crossing of the Hudson between Westchester and Rockland counties. The Tappan Zee river crossing was named by 17th century Dutch settlers. A petition and several pieces of proposed legislation have sought to restore the bridge's name to that of its predecessor. The bridge's official name, commemorating former New York Governor Mario Cuomo, has been controversial since its announcement. An opening ceremony for the south span was held on September 7, 2018, and traffic started using the new span three days later. Tappan Zee Constructors then began demolishing the old bridge. The north span officially opened to westbound traffic on August 26, 2017, and eastbound traffic temporarily began using the north span on October 6, 2017. The Left Coast Lifter (one of the world's biggest cranes) was instrumental in the construction of the bridge.
The process to replace the original bridge kicked off in 2012, and Tappan Zee Constructors began construction on the new spans in 2013.
The south span carries southbound and eastbound automobile traffic. The new bridge's north span carries the northbound and westbound automobile traffic of the New York State Thruway, Interstate 87 (I-87) and I-287 it also carries a shared use path for bicycles and pedestrians. It was built to replace the original Tappan Zee Bridge, which was located just to the south. Cuomo Bridge, is a twin cable-stayed bridge spanning the Hudson River between Tarrytown and Nyack in the U.S. Larger vehicles pay variable toll based on vehicle class and time of day ( cashless toll)
