SR 410 closed in both directions at White River Bridge for several days | Damage found during inspection

Recent damage from over-height load discovered during routine inspection. Closing expected to last several days.

The Washington State Department of Transportation  temporarily closed the state Route 410 White River Bridge after crews discovered damage to the bridge’s overhead support structure during a routine inspection early Saturday morning.

The closing is expected to last for several days. The damage from an over-height vehicle may have happened within the last week to two weeks.

The SR 410 White River Bridge has an arched steel overhead support structure, which is signed for 15 feet. The bridge strike occurred in the westbound lanes of the bridge. Low clearance warning signs are posted along the shoulder approaching the bridge.

“WSDOT bridge inspection teams believe this bridge was damaged by an over-height load,” said Assistant Regional Administrator Dave McCormick. “To keep drivers safe, we’ve closed the bridge until emergency repairs have been completed.”

WSDOT has selected contractor PCL Civil Constructors, Inc. to do the repair work, which is estimated to cost $200,000 or more.

“WSDOT engineers are working to analyze data to determine the extent of the damage,” said McCormick. “The bridge could be closed for several days while contractor crews make repairs.”

Detour information

WSDOT has closed SR 410 to all but local traffic at 244th Avenue Southeast in Enumclaw and Park Avenue in Buckley. Drivers traveling between Enumclaw and Buckley can detour via SR 164, SR 18, SR 167 and SR 410. Local residents can call (253) 372-3933 for a recorded message about the bridge status.

The SR 410 White River Bridge is a steel truss bridge built in 1949. It was last inspected in April 20, 2013. Approximately 20,000 vehicles use this stretch of SR 410 daily.

WSDOT publishes minimum and maximum bridge heights for each direction of travel on the WSDOT Commercial Vehicle Services website and the state route bridge vertical clearance trip planner. The minimum and maximum measurements may fall inside or outside the traveling lanes, including shoulders. If an operator has an oversized load between the minimum and maximum measurements they are responsible for checking the vertical clearance prior to travel.
