CHEHALIS - Work on the new Chamber Way overpass above Interstate 5 in Chehalis will reach another major milestone next week.

Beginning Wednesday, May 23, contractor crews working for the Washington State Department of Transportation will close the Chamber Way overpass. Crews will set up nighttime detours for both directions of I-5 before setting eight 127-foot-long bridge girders over the highway. Paving and barrier work will also take place in the median of I-5 during the interstate detour.

“Each bridge girder weighs approximately 120,000 pounds and is critical for supporting the deck of the new structure,” said WSDOT project engineer Frank Green. “Our contractor is making great progress and we appreciate the community’s understanding when we detour traffic for this work.”

Detour and lane closure information
WSDOT’s contractor, Quigg Bros. Inc., will need to detour nighttime interstate traffic while they install the bridge girders. All users of the highway will follow a signed detour using the off- and on-ramps at Chamber Way to continue back onto I-5.

  • Wednesday, May 23 to the morning of Thursday, May 24: A single lane on both directions of I-5 will close from 9 p.m. to 5 a.m., with all lanes of I-5 detouring to the Chamber Way off- and on-ramps, from 11 p.m. to 5 a.m.
  • Thursday, May 24 to the morning of Friday, May 25: A single lane on both directions of I-5 will close from 9 p.m. to 5 a.m., with all lanes of I-5 detouring to the Chamber Way off- and on-ramps, from 11 p.m. to 5 a.m.
  • Note: During the I-5 detour, Chamber Way will close between Louisiana Avenue and State Avenue from 8 p.m. to 7 a.m., to allow a free flow of interstate traffic through the intersections. Cyclists and pedestrians will follow Northwest State and Northwest Louisiana Avenues, crossing the highway at Northwest West Street.

Next steps
Construction will continue throughout the summer and is scheduled for completion this fall.
