CHEHALIS – Replacement of a damaged girder on the Chamber Way bridge will close northbound Interstate 5 and Chamber Way two nights next week. The closures come a week sooner than anticipated, thanks to early delivery of the replacement girder.

Northbound I-5 and the Chamber Way bridge will be fully closed the nights of Monday, Sept. 16, and Thursday, Sept. 19.

Drivers on northbound I-5 will use the Chamber Way ramps to detour around the closures. I-5 drivers will still be able to turn right off the ramp onto eastbound Chamber Way, but through traffic will not be able to cross I-5 using Chamber.

Damaged girder removal Sept. 16
Washington State Department of Transportation contractor crews will close northbound I-5 and Chamber Way from 11 p.m. Monday, Sept. 16, until 5 a.m. Tuesday, Sept. 17, for removal of a girder damaged by multiple hits from too-tall semi-truck loads.

Once the girder is out, crews will get the bridge ready for placement of the new pre-fabricated girder, which is traveling to the construction site from Tacoma.

Crews will replace supports in preparation for the new girder, inspect the structure and make repairs if needed.

New girder setting Sept. 19
Crews will again close northbound I-5 and Chamber Way from 11 p.m. Thursday, Sept. 19, until 5 a.m. Friday, Sept. 20, while they place the new girder.

The new girder will be lowered into place using a crane parked on the Chamber Way bridge. Once the new girder is secured, crews will reconstruct the section of bridge deck above it, splicing rebar and pouring new concrete to close up the gap in the deck.

The new concrete needs at least two weeks to dry and harden before crews can reopen the full width of the bridge to traffic.

Work on this $682,000 project is on schedule for completion in October.
