One down, one to go for the Governor Mario M. Cuomo Bridge - formerly the Tappan Zee Bridge

The first span of the 5km twin-span Governor Mario M. Cuomo Bridge - formerly the Tappan Zee Bridge - in New York opened August 25.

Tappan Zee Constructors, joint venture led by Fluor and including American Bridge, Granite and Taylor Bros., shift all four lanes of westbound traffic from the existing bridge to the new span overnight.

The four eastbound lanes will be shifted onto the new span in the autumn. Demolition of the old bridge can then get underway, allowing more room for construction of the adjacent second new span, said Hans Dekker, president of Fluor’s infrastructure business.

“We are proud of the Fluor-led joint venture team for advancing this landmark megaproject and look forward to building on this milestone to complete the second span next year,” said Dekker.  

The client, New York State Thruway Authority, started building the cable-stayed bridge across the Hudson River between Westchester and Rockland counties in late 2013. When finished next year, it will be the largest bridge in New York State history.

The cable-stayed main span is supported by eight 128m towers, which stand at 5° angles and feature a sleek, chamfered design. The iconic towers support 192 stay cables, which are made up of nearly 7,900km of steel strands.

In final configuration, the Governor Mario M. Cuomo Bridge will carry eight general traffic lanes - four each on the westbound and eastbound spans - breakdown/emergency lanes, space for future bus rapid transit and commuter rail and an advanced traffic monitoring system.

I Lift NY crane places first girder on New York’s Tappan Zee Bridge

One of the world’s largest cranes has placed the first steel girder assembly for the approach span of the new NY Bridge, often called the Tappen Zee Bridge in New York. The barge-mounted I Lift NY super crane with its nearly 100m boom slowly picked up the 125m unit from its delivery barge and gently lowered it onto concrete pedestals in the Hudson River, near the Rockland County side of the bridge. The super crane will install even larger sections of the new bridge, some of which weigh around 907tonne

Tappan Zee takedown into the Hudson River

A controlled explosion demolished the eastern span of the old cantilever Tappan Zee Bridge across the Hudson River near New York City. The bridge, nearly 5km long, was opened in 1955 to carry traffic between the southern New England area and other regions west of the Hudson. Around 140,000 vehicles used the bridge daily. But the old bridge had deteriorated substantially and would have been too expensive to maintain or keep open for lighter traffic use. It became redundant after the new bridge of the
