State Route 167 Puyallup River Bridge replacement
General contractor: Guy F. Atkinson Construction
Owner/developer: Washington State Department of Transportation
Primary designer: Jacobs Engineering Group
This design-build project replaced an existing historic landmark a 1925 Warren truss bridge with a new, wider northbound bridge.
Atkinson’s design differed from the Washington State Department of Transportation’s plan to build a new four-span concrete bridge to the west of the existing bridge. Instead, Atkinson built a three-span, 557-foot-long steel girder bridge within the existing northbound Warren truss bridge footprint. That change eliminated a proposed southbound widening, retaining wall, utility relocation, ground improvement and signalized intersection work.
Atkinson built new temporary piers and approach roadways, then rolled the Warren truss to the east for use as a temporary northbound detour, allowing crews to maintain northbound traffic during construction.
The steel bridge benefits included eliminating the in-water pier and fish window constraints, providing flexibility for future master plan construction, and accommodating the future levee widening. Once completed, Atkinson moved the historic Warren truss bridge intact to a location northwest of the project site for WSDOT’s future use.
