Peter Western Bridge.

The City of Burien announced this week that Hamilton Construction Company has been awarded – through a competitive bid process – the contract to construct the new Peter Western Bridge.

“Hamilton Construction has been in business for more than 80 years, constructing bridges and other transportation facilities throughout the Pacific Northwest,” the city said.

The contract award was for $4.59 million, which does not include design, permits, and other associated costs.

Design is completed, and construction is scheduled to begin the end of August and be completed by the end of 2020.

Previously, the city announced that construction would begin in early 2019.

The bridge, located in the 2200 block of S. 116th Street in Burien (map below) – was demolished after winter storm damage in 2017 significantly weakened the pilings.

As we previously reported, in February, 2017, the ravine below the 67-year old structure experienced severe erosion caused by a strong winter storm, significantly damaging the bridge’s support columns. The erosion undermined the structural integrity of the bridge, and the City closed it. The creek running through the ravine also moved, causing further erosion.

A few facts about the bridge:

  • It was built in 1950.
  • It underwent a seismic retrofit in 1996.
  • It was inspected in June 2016 by King County. The report states that there were no issues with scouring of the hillside.
  • There is an apartment complex as well as a few private residences near the bridge.
