Simpson Avenue Bridge Closed Till Further Notice in Hoquiam

“We recognize that closing the bridge creates a hardship for the community, and we will work with city officials and legislators to find a solution as quickly as possible,” Dayton said.

WSDOT hired divers on Tuesday to examine the bridge piers 35 feet underwater after WSDOT crews in recent weeks noticed unusual movement on the bridge. After removing a portion of the cofferdam that construction workers sank into place in the mid-1920s, divers were able to see scouring, marine boars and worm infestation, which led to the degradation of the piles – all of which factored into the engineer’s decision to close the bridge. 

In-water pier inspections are conducted on a five-year cycle. The last underwater inspection on the Simpson Avenue Bridge took place in January 2008.
