Traffic in both directions on Interstate 5 in Chehalis will be detoured overnight Monday for construction.
Traffic will be detoured via the Chamber Way off- and on-ramps from 11 p.m. Monday to 5 a.m. Tuesday.
The overpass at Chamber Way also will be closed from 9 p.m. to 5 a.m. Drivers should follow signs for the detour.
The construction is part of ongoing work to replace the Chamber Way overpass, which was damaged when a semitrailer hauling a pair of excavators hit the overpass in July 2016. The project is expected to be completed in fall 2018.
