A hole formed in the driving surface of the North Fork Lewis River Bridge on Interstate 5 north of La Center on Tuesday, closing the right lane from 5 p.m. till midnight as crews repair the road.
The concrete pavement crumbled away in the right lane of the bridge just south of Mile Post 20 and formed a hole, said Abbi Russell, spokeswoman for the Washington State Department of Transportation. The metal structure of crossbeams and girders supporting the concrete is still intact.
“This structure has that issue from time to time,” Russell said.
The aging bridge, built in 1968, gets heavy traffic from passenger vehicles and big rigs. An underbridge inspection truck will work to patch the hole with concrete.
Drivers can expect some congestion from the road work and are encouraged to take alternate routes.
