Bridges on Dayton Street in Kennewick and Filbert Road in Franklin County are among 47 in the state that will receive federal money for replacement or repairs.
The Washington State Department of Transportation announced the $80.6 million list of projects on Thursday.
The money comes from the federal Highway Bridge Program and is intended to replace or repair aging, obsolete and structurally deficient bridges.
"Some of these bridges are beyond the point of repair and need to be replaced in order to protect the traveling public," said Kathleen Davis, director of the state's Highways & Local Programs Division.
Never miss a local story.
The list includes $454,400 to replace the Dayton Street bridge that crosses a Columbia Irrigation District canal, and $375,000 to replace the Filbert Street bridge.
