DESCRIPTION

Bridges are some of our most eye-catching projects. We build and rehabilitate bridges of all types, from landmarks like the Bridge of Lions in St. Augustine, Fla., to interstate thoroughfares like Interstate Highway 10 over Florida’s Escambia Bay. We’ve overseen the seismic retrofitting of the Richmond-San Rafael Bridge in California, construction of the Cooper River Bridge (also known as Arthur J. Ravenel Bridge) in South Carolina, as well as worked on the iconic East River bridges in New York: the Brooklyn Bridge, Williamsburg Bridge, Manhattan Bridge and Robert F. Kennedy Bridge (formerly the Triborough Bridge).

155 miles per hour: The speed of Hurricane Ivan’s winds that ruined sections of the

Interstate Highway 10 twin bridges between Florida’s Escambia and Santa Rosa counties in

2004. Skanska designed and constructed two replacement bridges to stand 25 feet above

water, more than twice the height of the original bridges.

215 feet: The height of the Bayonne Bridge after a Skanska joint venture raises the roadway

by 64 feet. The bridge’s current 151-foot clearance cannot accommodate the next generation

of new Panamax container ships, which will begin service from Asia by about 2015, following

the widening of the Panama Canal.

1883: Year the Brooklyn Bridge, one of the oldest suspension bridges in the United States, was

completed. We’re currently reconstructing the approaches and ramps in both Manhattan and Brooklyn.

35,000 tons: The amount of waste concrete and asphalt, together with 5,400 tons of recovered steel,

that the Skanska team recycled at our 11th Street bridge replacement project in Washington D.C. Our

design-build team performed 70 percent of construction without affecting existing traffic flows.

78,000 vehicles: The number of cars, trucks and motorcycles that cross the Manhattan Bridge each

day. The 5,800-foot-long bridge, which spans the East River between the boroughs of Brooklyn and

Manhattan, was built in 1909. Years of use caused rapid deterioration to this historical and

architectural monument, forcing the New York City Department of Transportation to initiate a massive

reconstruction program. Skanska rehabilitated the bridge’s north spans.

2.5 miles: The length of the Cooper River Bridge. Skanska completed this design-build project in

Charleston one year ahead of schedule. The 1,546-foot main span, which is 186 feet above the river, is

one of the longest cable-stayed spans in North America.

17.6 miles of bridge/tunnel: The length of over-and-under water Chesapeake Bay Bridge Tunnel, one of the

Seven Engineering Wonders of the Modern World. We built the bridge-tunnel over three-and-a-half years through a

joint venture with four other contractors.

25 feet: The height of Los Angeles’ Gold Line Bridge’s basket-like concrete columns that pay tribute to the

indigenous people of the San Gabriel Valley and the oversize iconic roadside traditions of nearby Route 66.

Skanska completed the 600-foot-long bridge in 2013.

3.3 Million lbs: The weight of the steel Skanska used to strengthen the 350-foot tall main towers of the

Williamsburg Bridge, during its rehabilitation and seismic retrofitting. Intermediate towers were strengthened

with 1.8 million pounds of steel.

31 million lbs: The weight of extensive structural steel retrofit added to the Richmond-San Rafael Seismic Retrofit

Project in California, which included the strengthening of the four-mile long bridge’s truss components and tower

legs, the installation of special moment resisting pier frames, installation of seismic isolation bearings, viscous

dampers, and seismic restrainers.
