Atkinson Construction Relocates Puyallup Bridge Span

August 25, 2014

PUYALLUP, Wash. – Last month, Atkinson Construction successfully relocated the Highway 167 Puyallup River Bridge span to make way for a new, structurally sound replacement.

Given the 89-year-old bridge's structural inadequacy, the span is in need of modernization. However, the old span is being put to good use while Atkinson constructs a new bridge to take its place. To stabilize the existing bridge, Atkinson installed steel plates along the underside of the existing bridge’s steel truss to reinforce the structure so legal-weight trucks can continue to use it while the replacement bridge is completed.

Using powerful jacks, Atkinson lifted the 1.5 million-pound a couple of feet, then slide it over three feet at time, repeating the lift and slide move until the bridge was relocated 60 feet to its new position.

Although the new bridge will have the same number of lanes as the existing bridge, it is designed and being constructed to accommodate additional lanes should funding become available in the future.

The Highway 167 Puyallup River Bridge project marks Atkinson's sixth design-build endeavor with the Washington State Department of Transportation (WSDOT). Additional projects include the I-405/NE 8th Street to SR 520 Braided Ramps-Interchange Improvements, I-90 Snoqualmie Pass, and the SR 530 Reconstruction project.

Atkinson's scope of work also includes resurfacing the concrete along the southbound bridge deck. Construction of the new Puyallup River Bridge is scheduled for completion in late 2015.
