The Tappan Zee Bridge, officially named the Governor Mario M. Cuomo Bridge, is a twin cable-stayed bridge spanning the Hudson River between Tarrytown and Nyack in the U.S. state of New York. It was built to replace the original Tappan Zee Bridge, which was located just to the south. 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. The south span carries southbound and eastbound automobile traffic.
The process to replace the original bridge kicked off in 2012, and Tappan Zee Constructors began construction on the new spans in 2013. The Left Coast Lifter (one of the world's biggest cranes) was instrumental in the construction of the 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. Tappan Zee Constructors then began demolishing the old bridge. An opening ceremony for the south span was held on September 7, 2018, and traffic started using the new span three days later.
The bridge's official name, commemorating former New York Governor Mario Cuomo, has been controversial since its announcement. A petition and several pieces of proposed legislation have sought to restore the bridge's name to that of its predecessor.
The Tappan Zee river crossing was named by 17th century Dutch settlers. The Tappan Zee Bridge is the only crossing of the Hudson between Westchester and Rockland counties. The original Tappan Zee Bridge was a cantilever bridge built from 1952 to 1955. The bridge was 3 miles (4.8 km) long and spanned the Hudson at its second-widest point. It was the longest bridge in New York State, at a length of 16,013 feet (4,881 m) including approaches. 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. During its first decade, the bridge carried fewer than 40,000 vehicles per day.
By the 2000s, the old Tappan Zee Bridge was "decaying" and "overburdened". The deteriorating structure bore an average of 140,000 vehicles per day, substantially more traffic than its designed capacity. The collapse of Minnesota's I-35W Mississippi River bridge in 2007 raised worries about the Tappan Zee Bridge'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.
The Federal Highway Administration issued a report in October 2011 designating the Tappan Zee's replacement to be a dual-span twin bridge. The new bridge was to be built a few yards to the north of the existing bridge, connecting to the existing highway approaches of the New York State Thruway (I-87/I-287) on both river banks. The New York State Thruway Authority requested design proposals from four companies in 2012 and eventually received three project proposals. The authority awarded a $3.142 billion contract to Tappan Zee Constructors (TZC), whose proposal was not only the least expensive but also promised the shortest construction timeline and included plans to minimize environmental impact.
Originally, some motorists thought that bridge tolls could more than double (to $12-$15 for automobiles, eastbound only), rising to those of New York City's Hudson River crossings. However, the state passed legislation freezing the toll on the bridge at $5 through 2020 in its 2016 legislative session.
The new Tappan Zee Bridge was proposed to include four vehicle lanes on each span, for a total of eight lanes, as well as a shared-use bicycle and pedestrian path. Like its predecessor, the new Tappan Zee Bridge is to be administered by the New York State Thruway Authority. The authority is the project co-sponsor, along with the state Department of Transportation.
The New York Metropolitan Transportation Council added the Tappan Zee Bridge to its list of projects eligible for federal funds in August 2012. The United States Department of Transportation approved the plan on September 25, 2012. The approval process took fewer than 10 months as opposed to the traditional multi-year process as a result of being placed on a "fast track" for approval by the Obama Administration. On December 17, 2012, New York state officials dropped their proposal for a 45 percent increase on the state Thruway toll for trucks, while advancing a $3.14 billion project to replace the bridge. The project was funded through a public-private partnership.
Construction began as scheduled in October 2013, with completion targeted for 2017. TZC, the contractor, was composed of several design, engineering, and construction firms including Fluor Corporation, American Bridge Company, Granite Construction Northeast and Traylor Bros. The Left Coast Lifter was used to install groups of pre-assembled girders one full span at a time. The contractors were obliged to finish the bridge by 2018, after which the state would fine the contractors around $100,000 per day.
By the end of 2013, General Electric had completed four seasons of dredging to remove contaminants from the river bottom. Approximately 70 percent of the sediments targeted for dredging were removed (totaling more than 1,900,000 cubic yards (1,500,000 m3) of sediment).
On July 19, 2016, a crane used for the construction of the bridge collapsed onto the existing older bridge. Five people were injured, including three drivers and two bridge workers; no one was killed or critically injured.
The project timeline originally indicated that the old bridge would be closed in 2016 and that the demolition of the old bridge would begin in February 2017. The new northbound/westbound span opened on August 26, 2017. Southbound/eastbound traffic remained on the existing span until October 6, 2017, when it was shifted to the new northbound/westbound span to allow for the completion of the new southbound/eastbound span. The northbound/westbound span of the new Tappan Zee Bridge temporarily carried four lanes in both directions until the new southbound/eastbound span was completed.
After some delays, the project was later expected to be completed by June 15, 2018, at a cost of $3.98 billion. However, the scheduled opening was later pushed back to mid-September. The new southbound/eastbound span was supposed to open to traffic on September 8, 2018. An opening ceremony was held on that date, but the traffic shift itself was delayed when a piece of the old bridge came loose on September 7 while being demolished. The opening of the eastbound span, which was 160 feet (49 m) away from the old bridge, was delayed until the old bridge could be stabilized. After the old bridge was stabilized, all lanes were opened on September 11, 2018.
The demolition of the old bridge started in November 2017 with the removal of the first steel section from the Rockland County approach. The work continued to April 2018 including the removal of the truss sections. In May 2018, the 10-million-pound main span was removed, leaving only the east and west approaches. The original plan was to complete the remaining demolition by taking down spans piece by piece in order to minimize the environmental impacts. However, when the instability of the eastern span was discovered in September 2018, it was decided to destroy it outright. The explosive demolition of the eastern approach took place on January 15, 2019, while the western approach was lowered onto a barge on May 12, 2019 and hauled away.
In December 2018, the media reported that structural problems with the bridge had been covered up. Dozens of bolts holding the steel girders together had failed, and some bolts broke more than a year after they had been tightened into the plates that hold the girders together. A presentation by the whistleblower alleged that the bolts had broken due to hydrogen embrittlement, which weakened the metal. The number of failed bolts was abnormally high for a project the size of the new Tappan Zee Bridge. Engineering experts warned that the structural problems could compound, causing the girders to fall and the bridge to collapse.
The issue was known as early as February 2016, when New York state officials had begun testing some bolts for breaks. The Attorney General of New York began investigating whether structural problems with the bridge had been covered up in 2017. According to a report by the Times Union, the attorney general's office relied on other investigations of the bridge instead of conducting its own investigations, and the office did not treat the allegations as serious. Third-party consultant Alta Vista conducted its own study, concluding in late 2017 that hydrogen embrittlement was not the cause of the broken bolts.
In March 2021, some records relating to the case were unsealed. Following this, U.S. Representative Mondaire Jones, whose district encompasses the bridge, and all Republican members of the New York State Assembly requested that the United States Department of Transportation investigate the allegations of structural deficiencies. In response, the Federal Highway Administration issued a statement claiming it had "no safety concerns" with either of the Tappan Zee Bridge's spans. In a lawsuit filed that month, a whistleblower claimed that TZC had knowingly delivered many defective high-strength bolts and taken measures to hide evidence of the defects.
The new Tappan Zee Bridge is composed of two cable-stayed decks and has a total length of 16,368 ft (4,989.0 m; 3.1 mi; 5.0 km). The main span of both decks is 1,200 ft (370 m) and is approached on either side by 515-foot-long (157 m) side spans. Each deck carries four lanes of traffic in one direction, plus inner and outer shoulders. The clearance below is 139 ft (42 m). Upon completion, the new Tappan Zee Bridge became one of the widest cable-stayed bridges in the world, having a combined width across both decks of 183 feet (56 m). The new spans equal the width of the relatively short-span, cable-stayed Leonard Zakim Bridge in Boston. Turkey's 3rd Bosphorus bridge, completed in 2016, has a single deck about 192 feet (59 m) wide. The new Tappan Zee Bridge is intended to last at least 100 years.
Each span contains four cable-stayed towers (two on each side of the Tappan Zee), with eight total across the length of the bridge. The towers are 491 feet (150 m) tall and lean five degrees outward from the vertical axis. The towers are constructed of open-box beams, with cross beams linking the towers below each deck. The towers support a total of 192 cable stays, which consist of 4,900 miles (7,900 km) of steel strands. The decks of each span are composed of precast concrete panels, connected underneath by "edge girders" running parallel to the edges of each deck, as well as floor beams running perpendicularly to the deck. The cable stays are anchored to the outer faces of the edge girders underneath each span. The bridge is supported by 1,250 girders, each measuring up to 120 feet (37 m) long and 12 feet (3.7 m) high. They are secured to splice plates by about 500 bolts.
The north span has a bicycle and pedestrian path, which opened on June 15, 2020. This path connects the towns of Tarrytown and South Nyack and measures 3.6 miles (5.8 km) in length. It has visitor centers at each end, named after the counties of Rockland and Westchester. Both of these contain restrooms, brochures, and interactive displays. The Westchester visitor center also has vendors that operate daily. The path is split into two lanes with bikes on the east and pedestrians on the west. The path has six scenic overlooks known as "belvederes." Each belvedere is named after a local point of interest and provides Wi-Fi, a seating area, bike racks (on most), informational kiosks, and trash cans. The path also contains LED displays for warning messages.
The bridge is equipped with LED lights for the roadways and structures. The lights can be changed to a variety of colors for decorative purposes on major holidays such as Memorial Day and Christmas, traditional dates such as Mother's Day, Father's Day and St. Patrick's Day, and special commemorations throughout the year. The lighting system reputedly has the ability to be synced to music, although it has yet to be demonstrated.
The Tappan Zee Bridge charges tolls in the Westchester southbound/eastbound direction only. On weekdays, tolls are variable based on the New York State Thruway's vehicle classification system and the time of day, and are collected using a cashless toll system. On weekends, each vehicle class pays a flat rate. E-ZPass users pay the lowest rate possible, the rate normally charged from 12:00 midnight to 6:14 a.m., while other users are charged using the highest rate possible, the rate normally charged from 7:00 a.m. to 8:59 a.m. Class 2L vehicles, which have a height of less than 7.5 feet (2.3 m) and contain two axles, pay a flat rate of $6.83 at all times, $5.25 with a New York-issued E-ZPass, or $6.04 with an out-of-state E-ZPass. 
The Hudson Link BRT runs the HO3, HO5, HO7, and HO7X across the bridge. In the summer months Hudson Link also runs free shuttle buses on the route of the HO7 bus. Responding to widespread concerns about the lack of new public transit services, bridge planners agreed only to build one "dedicated express bus lane" in each direction for use during rush hour. Construction on the new bridge's bus lanes finished in 2020, leaving one bus lane in each direction. The bridge was also structurally built for expansion with commuter rail at a later date. The existing Tarrytown station of the Metro-North Railroad's Hudson Line is located about 2,000 feet (610 m) from the new bridge's eastern landing.
Governor Andrew Cuomo was successful in passing legislation to name the bridge after his late father, former Governor Mario Cuomo, on June 29, 2017. This has been met with significant opposition from residents of nearby localities. Many, including the daughter of former New York Governor Malcolm Wilson (whose name was on the original Tappan Zee Bridge), were vocal in their opposition to the name. A Reclaim New York Initiative poll of Rockland and Westchester county residents found only 14.7% of respondents supported the new name. As of November 29, 2017, over 100,000 people had signed a Change.org petition called "Return the Cuomo Bridge its original name: The Tappan Zee. That bridge is our history." Despite the official name, "Tappan Zee Bridge" remains a common name for the structure.
On December 6, 2017, State Assemblyman Kevin Byrne, a Republican from Mahopac in Putnam County, announced that he would introduce legislation to change the name of the bridge to the "Malcolm Wilson Tappan Zee Bridge". The old Tappan Zee Bridge had been named for Wilson from 1994 to June 2017. A compromise bill to rename the bridge the "Governor Mario M. Cuomo Tappan Zee Bridge" was later introduced and sponsored by both Senate Deputy Majority Leader John DeFrancisco, Republican of Upstate New York, as well as Assemblyman Byrne. On June 20, 2018, the State Senate voted 40–20 in favor of renaming the bridge. However, the effort failed after the Assembly's legislative session ended without the bill being put to a vote. After Cuomo's resignation in August 2021, a bill to change the official name to "Tappan Zee Bridge" was again proposed in the New York state legislature.

Why Replace the Tappan Zee Bridge? The Governor Malcolm Wilson Tappan Zee Bridge opened to traffic in 1955 and, until its retirement on October 6, 2017, was a vital artery for residents, commuters, travelers and commercial traffic. Bridge traffic grew to about 140,000 vehicles per day in 2016, far more than the Tappan Zee was designed to support. Heavy traffic, narrow lanes and the lack of emergency shoulders had the potential to create unsafe driving conditions. As a result, the bridge had twice the average accident rate per mile as the rest of the 570-mile Thruway system. Hundreds of millions of dollars were spent to maintain the structure in recent years, and the cost of maintaining it for the foreseeable future rivaled the cost of the new bridge, with no improvements to current traffic conditions. The New York State Thruway Authority retired the bridge on Oct. 6, 2017, after nearly 62 years of service.
