The document details various engineering projects undertaken by Skanska, emphasizing their significance, structural innovations, and recycling efforts. Key highlights include the reconstruction of bridges to accommodate modern traffic and the incorporation of sustainable practices, such as recycling substantial amounts of concrete and steel. Notable projects mentioned are the Bayonne Bridge elevation, the Williamsburg Bridge rehabilitation, and the Chesapeake Bay Bridge-Tunnel construction.

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.
5

6. 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.
6

7. 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.
7

8. 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.

9. 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.
9

10. 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.
