Atkinson Relocates Puyallup Bridge Span

PUYALLUP, Wash. – Last month, Atkinson successfully relocated the SR 167 Puyallup River bridge to make way for a new wider northbound bridge that meets today's design standards. To accomplish this, Atkinson constructed new temporary piers and approach roadways and rolled the Warren Truss to the east for use as a temporary northbound detour. 

 

Using powerful jacks, Atkinson lifted the 1.5 million-pound bridge several feet, then slid it over three feet at time, repeating the lift and slide movement until the bridge was relocated 60 feet into its new position.

 

Crews will construct a three-span, 557-foot-long steel girder bridge within the existing northbound Warren Truss bridge footprint. The steel bridge benefits include eliminating the in-water pier and fish window constraints on the schedule, providing flexibility for future master plan construction, and accommodating the future levee widening.

 

Construction of the new Puyallup River Bridge is scheduled for completion in late 2015. Once the project is complete, Atkinson will remove the historic Warren Truss bridge intact and store it northwest of the project site for WSDOT's future use.
