URS Corporation has been selected by the City of Seattle’s Department of Transportation to provide construction management services for Phase 2 of the South Spokane Street viaduct rehabilitation and reconstruction of the surface roadway. URS is providing construction management and contract administration services for the $60 million project, which will widen the existing viaduct. The project will nearly double the width of the existing viaduct and will expand traffic flow from two 10-foot wide lanes with no shoulders to three 11-foot lanes with shoulders in each directions. The work is expected to be completed in summer 2012.
A new ramp to and from 1st Avenue South will be constructed as part of the project, and an existing ramp at 4th Avenue South will be demolished. The project extends nearly three quarters of a mile, contains 158 drilled shafts up to 120 feet long, and includes three different types of bridge deck construction – pre-cast concrete girders, structural steel, and cast-in-place box girders. The work involves demolition and removal of access ramps and other portions of the existing system, retrofit of the viaduct structure, relocation of drainage and other utilities, and a closed circuit television system.
