The bridge replaces the original Tappan Zee Bridge, which was built in 1955 and demolished in 2017-2019. The northern carriageway (northern span) of the new bridge leads traffic to the north and west of the New York State Thruway Authority, and the southern carriageway (southern span) leads to the south and east. There is also a shared path for bicycles and pedestrians.

Preparations for replacing the original bridge began by the “Tappan Zee Constructors” consortium in 2012, and construction began in 2013. The Left Coast Lifter, one of the largest cranes in the world, played a key role in the construction of the bridge. The northern range was officially opened to traffic to the west on August 26, 2017; traffic to the east began temporarily on October 6, 2017 with the use of the northern range. Tappan Zee Constructors then began demolishing the old bridge. The opening ceremony for the southern span took place on September 8, 2018, and opened to traffic three days later.

The bridge's official name has been controversial since its announcement. A petition and legislative proposals have spoken out against putting Mario Cuomo's name on the bridge.

history

planning

The Federal Highway Administration published a document in October 2011 that identified the new Tappan Zee Bridge as a double bridge with two spans. The new bridge is to be built a few meters north of the existing bridge and connect to the existing freeway slip roads of the New York State Thruway (I-87 / I-287) on both banks of the river. The New York State Thruway Authority awarded the “Tappan Zee Constructors” (TZC) consortium the construction contract worth over US $ 3.142 billion from three project proposals. Construction work began on schedule in October 2013 with completion for 2017.[5]

Originally, many motorists feared that the tolls for the bridge could more than double (12 to 15 US dollars, only in an easterly direction), but the state passed a law in its 2016 legislative period that would reduce the toll on the bridge until 2020 was lowered to $ 5. The new Tappan-Zee Bridge was to have four vehicle lanes per route with a total of eight lanes as well as a shared bicycle and pedestrian path. Like its predecessor, the new Tappan Zee Bridge will be administered by the New York State Thruway Authority. The agency is the co-sponsor of the project along with the State Department of Transportation.

construction

The New York Metropolitan Transportation Council added the Tappan Zee Bridge to its list of eligible projects for federal funding in August 2012. The US Department of Transportation approved the plan on September 25, 2012. The project was funded through a public-private partnership. The new Tappan Zee Bridge was designed and built by Tappan Zee Constructors, LLC (TZC) - a consortium of design, engineering and construction companies including Fluor Corporation, American Bridge Company, Granite Construction Northeast and Traylor Bros. Groups of pre-assembled units were used for assembly Full span girders used. The General Electric company removed 1,500,000 m³ of contaminated sediment while dredging the river floor. On July 19, 2016, a crane used to build the bridge crashed onto the existing older bridge. Five people, three drivers and two bridge workers, were slightly injured.

completion

The project's original schedule was that the old bridge would close in 2016 and demolition of the old bridge would begin in February 2017. With a one-year delay, the new bridge to the north and west was finally opened to traffic on August 26, 2017 and the bridge in the opposite direction on September 11, 2018.[6][7]

When completed, the new Tappan Zee Bridge became one of the widest cable-stayed bridges in the world with a combined width across both decks of 56 m (183 feet). The new spans correspond to the width of the relatively short-span Leonard Zakim cable-stayed bridge in Boston. The new bridge should last at least 100 years. Demolition of the old bridge began in November 2017 with the removal of the first section on the Rockland County side. Work continued through April 2018, including the removal of the truss sections. In May 2018, the outriggers were removed so that only the east and west entrances remained. Originally, the remaining parts of the bridge were to be dismantled piece by piece to minimize environmental damage. However, when the instability of the eastern parts of the bridge was discovered in September 2018, it was decided to demolish this part by blasting it on January 15, 2019. The remaining western parts of the bridge were loaded onto a barge and removed on May 12, 2019.

Tolls

The Tappan Zee Bridge only charges tolls in the south / east. On weekdays, tolls are variable based on the New York State Thruway vehicle classification system and the time of day and are collected using a cashless toll system. Each vehicle class pays a flat rate at the weekend. E-ZPass users pay the lowest possible rate, which is usually charged from midnight to 6:14 am, while other users pay the rate which is normally charged from 7:00 am to 8:59 am. Class 2L vehicles that are less than 7.5 feet (2.3 m) in height and contain two axles pay a flat fee of $ 5.00 or $ 4.75 at all times with a New York-issued E-ZPass .[8]

Bicycle pedestrian path

On June 15, 2020, the cycle-pedestrian path on the northern span of the bridge was opened. The trail has six viewpoints known as “Belvederes”. Each Belvedere is named after a local attraction and offers WiFi and a seating area.[9]

lighting

The bridge is equipped with LED lights for the roads and bridge elements. The lighting can be changed to different colors for decorative purposes on major holidays such as Memorial Day and Christmas, traditional days such as Mother's Day, Father's Day and St. Patrick’s Day, and special commemorations throughout the year.
