MARYSVILLE — Drivers who use southbound State Route 529 to travel from Marysville to Everett should plan for nightly closures of the highway this week.
The southbound lanes of the SR 529 Snohomish River Bridge will be closed as contractor crews working for the Washington State Department of Transportation continue replacing the heavy pieces of machinery that operate the southbound drawspan.
The bridge will be closed nightly from 8 p.m. to 4 a.m. the evening of Monday, Sept. 23, through the morning of Friday, Sept. 27. Southbound drivers will be detoured to I-5 in Marysville.
Crews are replacing four steel axles, wheels and dozens of counterweight cables on the southbound lift span. The lift mechanisms are showing signs of wear and fatigue after years of raising and lowering 250 tons of counterweight with each drawspan opening.
More information about the bridge repair work is available at www.wsdot.wa.gov/projects/sr529/snohomishbridgerepair. Video of the bridge opening and closing is available on the WSDOT YouTube channel. Photos are also available on Flickr.
