As an integral conduit within the New York Metropolitan Area, it connects South Nyack in Rockland County with Tarrytown in Westchester County in the Lower Hudson Valley. Federal and state authorities are currently constructing a replacement bridge, the New Tappan Zee Bridge, that will cost at least $4 billion. The bridge is part of the New York State Thruway mainline and carries the highway concurrency of Interstate 87 and Interstate 287. The span carries seven lanes of motor traffic. The center lane can be switched between eastbound and westbound traffic depending on the prevalent commuter direction ; on weekdays the center lane is eastbound in the morning and westbound in the evening. The switch is accomplished via a movable center barrier which is moved by a pair of barrier transfer machines. Even with the switchable lane, traffic is frequently very slow. The bridge is one of the primary crossings of the Hudson River north of New York City ; it carries much of the traffic between southern New England and points west of the Hudson. It is the longest bridge in the State of New York. The total length of the bridge 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, the skyline of which can be seen from the bridge on a clear day. As of April 2016, each eastbound passenger vehicle that drives under a gantry is charged a toll of $4.75 via E-ZPass, $5.00 by mail, or $3.00 if on the Commuter Plan ( which charges a minimum of $60 a month, requiring a minimum of 13 crossings to attain an average cost below the normal E-Z pass rate ). Westbound crossings are toll - free. As of January 2017, the E-ZPass discount only applies to New York issued E-ZPasses. Customers using E-ZPass accounts issued by other states are charged the full cash rate of $5.

The proposal was overridden by New York State Governor Thomas E. Dewey, who wanted to construct a bridge to connect the New York State Thruway across Westchester to the New England Thruway. The Port Authority promised its bondholders that it would not allow any other entity to construct a river crossing within its jurisdiction, which reached to a point one mile ( 1.6 km ) south of Nyack on the western shore of the Hudson River and across to Tarrytown on the eastern shore. The bridge was built on a very tight budget of $81 million ( 1950 dollars ), or $796 million in 2014 dollars. A May 10, 1950 editorial in The New York Times suggested that a site in southern Dobbs Ferry or northern Hastings - on - Hudson, where the Hudson narrowed considerably from its three - mile ( 5 km ) width at Tappan Zee, would be a more appropriate site, and suggested that Governor Dewey work with his counterpart, Governor of New Jersey Alfred E. Driscoll, to craft a compromise that would offer Thruway customers a discounted bridge fare at a more southerly crossing. Two days later, Governor Dewey announced that the Port Authority had dropped its plans to construct a bridge of its own, and that the bridge 's location would be close to the Tarrytown - Nyack line, just outside the Port Authority 's jurisdiction. Dewey stated that World War II military technology would be used in the bridge 's construction. The site of the bridge, at the Hudson River 's second - widest point, added to construction costs. The site was chosen to be as close as possible to New York City, while staying out of the 25 - mile ( 40 km ) range of the Port Authority 's influence, thus ensuring that revenue from collected tolls would go to the newly created New York State Thruway Authority, and not the Port Authority. A unique aspect of the design of the bridge is that the main span is supported by eight hollow concrete caissons. Their buoyancy supports some of the loads and helps reduce costs. The bridge was designed by Emil Praeger of the Madigan - Hyland engineering firm. Captain Praeger helped develop floating caissons during World War II when the Allied forces needed to create and protect portable harbors for the 1944 invasion of Normandy. Construction started in March 1952 and the bridge opened to traffic on December 15, 1955, along with a 27 - mile ( 43 km ) long section of the New York State Thruway from Suffern to Yonkers. New York State Governor W. Averell Harriman signed a bill on February 28, 1956, to officially name the structure the Tappan Zee Bridge. In 1994, the name of Malcolm Wilson was added to the bridge 's name upon the 20th anniversary of his leaving the governor 's office in December 1974, though it is almost never used when the bridge is spoken about colloquially. The bridge is expected to be decommissioned in October 2017. Replacement bridge Main article : New Tappan Zee Bridge The superstructure, which was constructed during a period of material shortages during the Korean War Construction of the new Tappan Zee Bridge. The new Tappan Zee Bridge being constructed next to the original The deteriorating current structure bears an average of 138,000 vehicles per day, substantially more traffic than its designed capacity. Unlike other major bridges in metropolitan New York, the Tappan Zee was designed to last only 50 years due to material shortages during the Korean War at the time of its construction. The new bridge is intended to last at least 100 years. The collapse of Minnesota 's I - 35W Mississippi River bridge in 2007 raised worries about the Tappan Zee 's structural integrity. These concerns, together with traffic overcapacity and increased maintenance costs, escalated the serious discussions already ongoing about replacing the Tappan Zee with a tunnel or a new bridge. Six options were identified and submitted for project study and environmental review. In 2009, the Tappan Zee Bridge was featured on The History Channel `` The Crumbling of America '' showing the infrastructure crisis in the United States. Many factors contribute to the precarious infrastructure of the bridge, which has been called `` one of the most decrepit and potentially dangerous bridges '' in the U.S. Engineering assessments have determined that `` everything from steel corrosion to earthquakes to maritime accidents could cause major, perhaps catastrophic, damage to the span, '' prompting one of the top aides in the New York state governor 's office to refer to the Tappan Zee as the `` hold - your - breath bridge. '' A 2009 state report noted that the bridge was not built with a plan that was `` conducive to long - term durability '' and that the Tappan Zee 's engineers designed it to be `` nonredundant, '' meaning that one `` critical fracture could make the bridge fail completely because its supports could n't transfer the structure 's load to other supports. '' The Metropolitan Transportation Authority ( MTA ) studied the feasibility of either including a rail line across the new bridge or building the new bridge so a new rail line can be installed at a future date. Commuter rail service west of the bridge in Rockland County is limited, and the MTA studied expansion possibilities in Rockland County that would use the new bridge to connect with Metro - North 's Hudson Line on the east side of the bridge along the Hudson River for direct service into Manhattan. On September 26, 2008, New York state officials announced their plan to replace the Tappan Zee Bridge with a new bridge that included commuter - train tracks and lanes for high - speed buses. The bridge was estimated to cost $6.4 billion, while adding bus lanes from Suffern to Port Chester was estimated to cost an additional $2.9 billion. Adding a rail line from the Suffern Metro - North station and across the bridge, connecting with Metro - North 's Hudson Line south of Tarrytown, would have added another $6.7 billion. The plan was reviewed for its environmental impacts. In 2013, the New York State Thruway Authority began building the new Tappan Zee Bridge to the north of the old bridge, which will be a double - span bridge ( four lanes per span in opposite directions ) with designated bus lanes. Construction began as scheduled during 2013, with completion targeted for 2017. The northbound / westbound span opened on August 25, 2017. Southbound / eastbound traffic will remain on the old span until fall 2017, when it will be shifted to its respective span. After some delays, the project is currently expected to be completed by June 15, 2018 at a cost of $3.98 billion. Suicide prevention The Tappan Zee Bridge as seen from a train on the eastern shore of the Hudson River From 1998 to 2008, more than 25 people committed suicide on the Tappan Zee Bridge, according to the New York State Thruway Authority. On August 31, 2007, NYSTA officials added four phones -- two each on the Rockland and Westchester sides -- that connect callers via the National Suicide Prevention Lifeline crisis hotline to counselors at LifeNet or Covenant House. Signs reading `` Life is Worth Living '' and `` When it seems like there is no hope, there is help '' have been placed on the bridge. Suicide fencing and traffic cameras have also been installed along the bridge, and bridge staff have been trained in suicide prevention. On October 14, 2012, Newsday reported that the Tappan Zee Bridge was called the Golden Gate Bridge of the East, and `` The new Tappan Zee, which is in the works, will include fencing designed to thwart jumpers. '' The most famous and notorious suicides on the Tappan Zee Bridge are those of Scott Douglas on January 1, 1994, after murdering his wife, Anne Scripps ; and on September 24, 2009, of his stepdaughter Annie Morrell Petrillo, who jumped from that same bridge to her death. A US military employee jumped from the bridge to her death in 2010.
