Frequently Asked Questions

Why did the Tappan Zee Bridge need to be replaced?

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. The bridge, which was designed to carry up to 100,000 vehicles per day, handled an average of 140,000 vehicles daily, and traffic congestion and delays were regular occurrences. Heavy traffic, narrow lanes and the lack of emergency shoulders often contributed to congestion and frustration for motorists. As a result, the bridge had twice the average accident rate per mile as compared to the rest of the 570-mile Thruway system. In recent years, hundreds of millions of dollars were spent to maintain and repair the bridge. Had the bridge not been replaced, the Thruway Authority would have needed to spend an additional $3 billion to $4 billion over the next 20 years to ensure its structural integrity.

How will the project reduce traffic congestion?

The Tappan Zee Bridge had only seven lanes, some of which were narrower than the current standard lane width of 12 feet. The new bridge will have eight, 12-foot-wide lanes and wider shoulders. The shoulders of the new crossing will greatly reduce the traffic impact of disabled vehicles and accidents, which caused massive tie-ups on the old bridge. The incline approaching the main span will not be as steep, allowing large trucks to maintain consistent speed and reduce engine and braking noise. The ability of trucks to maintain highway speed will also reduce speed differential with passenger vehicles which lessens lane changes and potential for accidents. There will also be gently banked curves to further smooth traffic flow and reduce accidents. In addition, the new bridge is being built with space to accommodate dedicated bus lanes that have been shown to reduce travel times for all vehicles. In April 2016, cashless tolling went into effect, eliminating the need for eastbound drivers to slow down or stop and idle at a toll plaza.

How long will it take to build the bridge?

The completed twin-span bridge is scheduled to be fully opened in 2018.

How long will the new bridge last?

The new bridge is being built to last 100 years before any major structural maintenance is required.

Who is building the new bridge?

The bridge was designed and is being built by Tappan Zee Constructors (TZC), a consortium of some of the world’s best-known and most highly regarded design, engineering, and construction firms, including Fluor, American Bridge, Granite Construction and Traylor Bros., along with key design firms HDR, Buckland & Taylor, URS, and GZA. TZC is working closely with a team of employees from the Governor’s office, the New York State Thruway Authority and the state Department of Transportation.

How much will the new bridge cost?

The project cost is $3.98 billion.

How is the new bridge being paid for?

The Thruway Authority closed on a $1.6 billion, long-term, low-interest loan through the U.S. Department of Transportation’s Transportation Infrastructure Financing and Innovation Act (TIFIA) program in December 2013, the largest loan in the history of the program at the time. During the past two years, $2 billion in bank settlement funds have been committed to support Thruway capital improvements and help pay for the New NY Bridge project. This funding will also freeze tolls on the entire Thruway system until at least 2020. While the state continues to seek innovative funding options, the remainder of the cost of the new bridge will be financed with Thruway Authority bonds.

Have tolls for the new bridge been determined?

No. Governor Cuomo has frozen tolls at current levels until at least 2020 and has called on the Thruway Authority to establish a resident discount program for drivers living in Rockland and Westchester counties.

How many lanes will the new bridge have?

The new twin-span bridge will have eight general traffic lanes—four in each direction. Space will also be provided for disabled vehicles, emergency responders and bus rapid transit. There will also be a shared-use path for bicycles and pedestrians.

When will traffic from the first span of the new bridge be transferred to its second span?

At 96-feet-wide, the westbound span of the Governor Mario M. Cuomo Bridge is temporarily accommodating eight lanes of traffic, four in each direction. The lanes are similar in width to those on the Tappan Zee Bridge. The landings of the old bridge are being taken down so the landings of the second, or eastbound, span can be constructed. Following completion of the second span, eastbound traffic will then be permanently shifted off the westbound span onto the eastbound span. Upon full completion, each span will have four general traffic lanes (all 12-feet-wide), breakdown/emergency access lanes, and space to accommodate dedicated bus lanes. The westbound span will include a bike/pedestrian path and six scenic overlooks.

What will happen to the Tappan Zee Bridge?

The Tappan Zee Bridge is being carefully dismantled using the I Lift NY super crane and other equipment. Many concrete and steel elements are being repurposed or recycled.

Will there be pedestrian and bicycle access?

Yes. Bicyclists and pedestrians will enjoy a 12-foot-wide shared-use path on the northern side of the new westbound span. The path will also have six scenic overlooks.

Who oversees the project for the Thruway Authority?

Jamey Barbas, P.E., is the Project Director. Ms. Barbas has more than 30 years of experience in bridge design, construction and inspection with a special emphasis on complex and long-span bridges. She is an expert in leading major infrastructure projects and in alternative delivery methods such as design-build.

What does "design-build" mean?

Design-build is an alternative to the traditional construction method of “design-bid-build.” Under a design-build contract, the contractor that builds the structure is also responsible for the development of the design. Design-build shifts much of the financial risk to the contractor. Design changes under the design-bid-build system often lead to project delays and cost overruns that are borne by taxpayers and toll payers.

Will the new bridge have mass transit?

The new bridge will have space for dedicated express bus lanes for bus rapid transit from the time it opens in its final twin-span configuration. The new bridge is also being built with the structural capacity to handle rail in the future. A Mass Transit Task Force studied short, medium and long-term options, as well as potential funding sources. The task force proposed its recommendations in early 2014.

What is bus rapid transit?

Bus rapid transit (BRT) is a state-of-the-art bus system recommended in the short term by the Mass Transit Task Force. The BRT system—known as the Lower Hudson Transit Link—will provide frequent, direct service and feature enhancements designed to get more drivers out of their cars including, faster travel times, on board wi-fi, real-time bus arrival information and simplified payment systems. The state Department of Transportation is overseeing its implementation.

What is cashless tolling?

Implemented for the Tappan Zee Bridge in April 2016, cashless tolling allows motorists to pay their toll while maintaining highway speeds. The system, which now serves the Governor Mario M. Cuomo Bridge, collects tolls via E-ZPass and Tolls by Mail, detecting classes of vehicles and applying the correct charge. If you have E-ZPass, your toll is collected using the same process that you are already familiar with. If you do not have E-ZPass, cameras photograph your vehicle’s license plate as it passes under the overhead equipment. A bill is then automatically sent to the registered owner by U.S. Mail.

What measures will be used on the new bridge to deter suicide attempts?

The Governor Mario M. Cuomo Bridge will include several measures to deter suicides. In addition to increasing the existing number of crisis hotline phones, both spans will feature climb-deterrent fencing on all bridge edges. A new high-tech video surveillance system will also be installed and monitored 24 hours a day, seven days a week.

Why build a new bridge and not a tunnel?

The most recent estimates for a tunnel under the Hudson River put the cost at $8 billion and included a construction period that would exceed that for a new bridge. Because of the topography in the region, a tunnel would have to be seven to eight miles long (compared with the 3.1-mile new bridge), and a substantial amount of private property would have to be taken in both Rockland and Westchester counties. Unlike the new bridge—which will utilize the same basic landing areas on both sides of the Hudson River as the Tappan Zee Bridge—a tunnel would require new connections to be built where it meets the Thruway (I-87/I-287) in Rockland and Westchester. The objective to facilitate potential future rail would have additional complexities for a tunnel solution.

What is the Community Benefits Program? How can I apply for funding?

The Community Benefits Program is a $20 million fund made up of equal contributions from the Thruway Authority and Tappan Zee Constructors, LLC. Projects eligible for consideration are those that maintain and enhance natural assets, local infrastructure, safety, recreational opportunities, and quality of life for communities in Rockland and Westchester counties. The program will be available through 2017. For more information on how to apply, please visit the Community Benefits Program page.

How is construction noise being mitigated?

The loudest construction activities, such as pile-driving, are limited to daytime hours (7 a.m. to 7 p.m.), are not allowed before noon on Saturdays, and are prohibited entirely on Sundays. Additionally, construction activities cannot produce noise levels of 70 decibels or above between the hours of 10 p.m. and 6 a.m.
Twenty-four-hour noise and vibration monitors post information to the project website, and a 24-hour hotline (1-855-TZ-BRIDGE) is available to report excessive noise. The builder, Tappan Zee Constructors, LLC, has one hour to mitigate the noise-causing activity above allowed levels. If the activity continues after that time, the Thruway Authority project manager can shut down the operation.

What about dust and air pollution?

Twenty-four-hour air quality monitors are located throughout the construction area with real-time results posted on our website. The contractor is required to use the most stringent (EPA ‘Tier 3’) dust and diesel particulate filters on its construction equipment.

What is being done to safeguard river life?

In construction as well as design, the New NY Bridge team has worked diligently to reduce the environmental impacts associated with the project. Examples include relocation of thousands of live adult oysters to preserve the shellfish population, tagging of Atlantic sturgeons to track and monitor as they pass through the construction zone, and falcon nest boxes on the old and new bridge. To learn more about our commitment to environmental stewardship, visit the FEIS page on the New NY Bridge website.

How can I learn about job opportunities on the project?

The Thruway Authority and Tappan Zee Constructors, LLC have established a partnership with the New York State Department of Labor to get as many local workers hired on the project as possible. To find out about employment opportunities, visit the New York State Department of Labor website.

How can my company apply for subcontracting work on the project?
