The $3.98 billion project to construct the 3.1-mile bridge — the first cable-stayed bridge across the Hudson River — and its ancillary facilities is one of the largest in the United States and the biggest in the history of the New York State Thruway Authority.

Operations to shift four lanes of Westchester-bound traffic to the new span will begin at approximately 8 o'clock tonight, weather permitting, with the first cars crossing early Saturday.

The Governor Mario M. Cuomo Bridge project replaces the retired 62-year-old Tappan Zee Bridge with two new state-of-the-art cable-stayed spans - one Rockland-bound and one Westchester-bound.

The first, Rockland-bound span opened last year in a temporary traffic configuration comprised of four traffic lanes in each direction to allow design-builder Tappan Zee Constructors to complete construction of the second span in the footprint of the old bridge at its landings. The new bridge will serve more than 140,000 motorists each day.

Eastbound motorists will have access to four general traffic lanes and emergency shoulders, and a dedicated bus lane will open next month for eastbound traffic. The fully completed project will also include a bicycle and walking path.

Rockland-bound motorists will continue to use their current four lanes on the westbound span. In the coming weeks, the four lanes of westbound traffic will be shifted to the opposite side of the span—where the eastbound traffic was previously—to allow for on-bridge construction of the bicycle/pedestrian path and its six overlooks.

The Governor Mario M. Cuomo Bridge is the first cable-stayed bridge across the Hudson River. Featuring eight 419-foot towers standing at a five-degree angle, the twin-span bridge has a total of 192 stay cables that would stretch 14 miles if laid end-to-end. A cable-stayed bridge uses steel cables placed at an angle to connect the bridge deck to vertical towers that extend high above the roadway.

More than 220 million pounds of all-American steel was used to build the bridge. Approximately 7,000 workers have contributed to date and nearly 11.5 million work hours have been dedicated to the project.

Designed to last 100 years without needing major maintenance, the Governor Mario M. Cuomo Bridge is one of the biggest active bridge projects in the nation and the largest in the history of the New York State Thruway Authority. The project has been recognized across the nation, including by former President Barack Obama, who put it at the top of his list of critical infrastructure priority projects.
