Federal funding totaling $10.7 million will allow Snohomish County to replace four bridges deemed structurally deficient.
The funds, which can only be used for bridge repairs, will cover as much as 80 percent of the total cost of building four new bridges. Snohomish County will add $2.7 million in road fund dollars.
Bridge design and permitting will begin in 2011 with construction on the first bridge likely in 2013, with the last of the four bridges completed by 2015.
“Since 2008, we’ve replaced five other bridges and made repairs to another 80, keeping our roads safe and passable,” said County Executive Aaron Reardon. “We’ll continue locating funds for future road work that keeps traffic moving and people safe.”
With an estimated cost of $2.4 million, Swamp Creek Bridge #504 in Bothell will likely be the first under construction. Built in 1958, Swamp Creek Bridge on Locust Way is a heavily traveled north-south route between Snohomish and King counties.
Pilchuck River Bridge #581, southwest of Granite Falls off of State Route 92, was built in 1960 and will be replaced for $4.5 million. Howard Creek Bridge #496, built in 1976 and located on Index-Galena Road, is about 7.5 miles east of Index. The 61-foot-long bridge will cost close to $2.4 million to replace.
Finally, Bridge #540, spanning the South Fork of the Sauk River, is about 33 miles east of Granite Falls. Built in 1986, it is 203 feet in length. Replacement will cost about $4.1 million.
The three bridges over the South Fork of the Sauk River, the Pilchuck River and Howard Creek are primarily made of timber. Two of these bridges also provide sole access to neighboring homes.
The county inspects bridges annually to maintain safety.
