Needs & benefits

The State Route 162 Spiketon Creek Bridge in Buckley closed Aug. 16, 2018 after crews surveying the bridge in preparation for a month-long deck repair project discovered up to four inches of pier settlement. WSDOT’s goal with the originally scheduled deck repairs was to keep the bridge operational until 2026, when it was scheduled to be permanently replaced. Unfortunately, the recent discovery changed that timeline.  Out of concern for public safety, crews closed the bridge and a detour for the 5,600 daily motorists who had been crossing the bridge was implemented immediately using Mundy Loss Road, SR 410 and SR 165.

After working extensively with the community and elected officials, WSDOT made the decision to restore the crossing with a temporary span bridge and keep the current permanent bridge replacement schedule. Current scheduling shows the temporary bridge will open to traffic in December 2019. A permanent bridge replacement project is scheduled to occur sometime during 2026. More details about that project will be announced closer to the advertisement date. 

The temporary bridge will be a modular, steel bridge that will sit just above the existing structure. The temporary crossing will be a two-lane bridge, with one lane in each direction with no load restrictions. Users of the Foothills Trail will encounter short, intermittent closures during construction. WSDOT will announce any closures as they are scheduled.

WSDOT published a blog post that addressed much of the community’s concerns with repair vs. replacement, timeline and funding.
