American engineering and construction company Fluor-led joint venture Tappan Zee Constructors has completed the final span of the Governor Mario M Cuomo Bridge in New York, which will replace the old Tappan Zee Bridge.
After the opening of the bridge, all four lanes of eastbound traffic will shift to the new second span. Construction began in late 2013. The first span of the bridge opened to Rockland-bound traffic in August 2017.
The bridge was scheduled for inauguration on 8 September 2018, but was postponed due to some technical problems.
The eastbound span comprises four general purpose traffic lanes, two emergency shoulders, a dedicated bus lane and an advanced traffic monitoring system.
The westbound bridge will continue to be in a temporary configuration during the completion of the bridge’s shared-use path connecting Westchester (New York) and Rockland (New York) counties for pedestrians and cyclists.
The New York State Thruway Authority, in partnership with the Fluor-led joint venture of Tappan Zee Constructors, comprising American Bridge Company, Granite Construction Northeast and Taylor Bros, has replaced the old bridge with the 3.1-mile, twin-span, cable-stayed bridge on the Hudson River between Westchester and Rockland counties.
Design firms HDR, Buckland & Taylor, URS and GZA were also involved in the project.
Eight 419ft towers support the cable-stayed main span. The towers stand at five-degree angles and feature a sleek, chamfered design. These towers support 192 stay cables, made up of 4,900 miles of steel strands.
Fluor’s infrastructure business line president Terence Easton said: “Fluor is honored to have been the lead design-builder for this project. We are proud of the team that delivered the Governor Mario M Cuomo Bridge to New York. This is a landmark project that provides a vital link to the region and improves daily commerce.”
The Governor Mario M Cuomo Bridge is one of the largest single design-build contracts for a transportation project in the US and is the largest bridge project in New York state history.
