ConDig (07-Dec-17).  Heavy civil construction contractor Kiewit Infrastructure has bagged a $192 million design-build deal to revamp the crumbling Arlington Memorial Bridge, in Washington DC.

The Omaha, Nebraska-based company was selected by the Federal Highway Administration (FHWA) ahead of Skanska USA and Wagman Heavy Civil, which were named on the shortlist in May.

Under the contract, Kiewit will build an independent shoring system to support the existing bascule span superstructure and its counterweights instead of the existing trunnion posts; repair of the concrete arches and stone facades on the 10 approach spans and reconstruction of the bridge deck and sidewalks and the resurfacing of all travel lanes.

The 2,162 feet long and 94 feet wide bridge, originally designed by McKim, Mead & White, opened to traffic in 1932 but has recently started to deteriorate.

It consists of ten reinforced concrete arch approach spans and a double leaf bascule span at the bridge’s center. Eight of the 10 approach spans convey the Potomac River under the bridge.

Two smaller concrete arches span the George Washington Memorial Parkway (GWMP) and Ohio Drive SW, at each end of the bridge.

Kiewit has a history of bridge rehabilitation projects and recently retrofitted several bridges in the San Francisco Bay Area, Interstate H-3 project in Hawaii, and also built the world’s largest geodesic dome at Henry Doorly Zoo in Omaha.
