Update: Please note, the work to reopen the Koontz Road bridge, over I-5, is complete and the overpass reopened to traffic at 1 p.m., Tuesday, May 30.

Nighttime detours planned through spring

Napavine – Over the last 14 months, the closure of Koontz Road over Interstate 5 near Napavine has forced drivers to take the long way home. But those long commutes will soon end.

Next week, contractor crews working for the Washington State Department of Transportation will begin work to repair the bridge support structure that was damaged by an unpermitted oversized load on Dec. 8, 2015.

“Each bridge repair project is unique, requiring careful coordination and design to get it right,” said WSDOT Project Engineer Dewayne Matlock. “Having a good detour in place gave us time to plan this project to minimize construction closures on I-5.”

To replace the two damaged concrete girders, and a portion of the bridge deck that spans over I-5, WSDOT’s construction contractor, Steller J Corporation, will need to detour nighttime interstate traffic. Drivers will follow a signed detour using State Route 508, Jackson Highway, US 12 back to I-5.

Upcoming work schedule

  • Beginning Tuesday, May 30:  Both directions of the Koontz Road bridge over I-5, near Napavine, are open to traffic.

The insurance companies for the responsible parties are funding the $2.9 million project that will also repair the damaged 93rd Avenue Southwest overpass in Tumwater. The work on Koontz Road will be complete in late spring 2017.
