Structurally deficient Snohomish County bridges

With last week’s collapse of the I-5 bridge over the Skagit River, all eyes turned to the various lists and ratings of bridges nationwide.

The federal government keeps a list, which designated the Skagit River bridge as “fuctionally obsolete” (its design is outdated) but structurally safe.

Snohomish County keeps a list, which has 14 of 200 county-road bridges cited as “structurally deficient.”

And the state of Washington keeps a list, last updated in 2011, which has seven state highway bridges in Snohomish County categorized as structurally deficient. Structurally deficient doesn’t mean unsafe. It means it’s time for repair or replacement. Two of those state-managed bridges have since been repaired or replaced.

Four of the seven bridges serve the short but busy stretch of Highway 529 between Everett and Marysville. One of those, across Ebey Slough, has recently been replaced.
