WSDOT slows southbound Steamboat Slough Bridge traffic after structural concerns

MARYSVILLE — Concerns with aging bridge connectors has led the state Department of Transportation to slow traffic to 25 miles per hour Thursday on 96-year-old southbound Steamboat Slough Bridge.

The speed change, from 55 mph, on Highway 529 takes effect immediately.

The southbound bridge is 96 years old and was rebuilt in 1993.

“The bridge remains safe for travel, but regular inspections discovered 12 of the original gusset plates – which connect steel beams on the bridge – need to be replaced,” a press release from the state transportation department reads. “The lower speed limit reduces vibrations on the bridge, which lessens stress on the entire bridge structure.”
