Traffic heading both directions on Interstate 5, from the junction with Interstate 205 to the North Fork Lewis River Bridge, will see up to two lanes closed in either direction this week through Saturday morning.
The Washington State Department of Transportation said the closures will run nightly, from 7 p.m. to 6 a.m., until Saturday morning. Work will depend on the weather cooperating, but crews will be replacing concrete panels, according to WSDOT.
