Travelers on Interstate 5 between Lewis and Cowlitz counties should expect lane closures and delays, a news release from the Washington State Department of Transportation (WSDOT) stated.
Starting Sunday, Sept. 21, the WSDOT crews will install RPM’s, or raised pavement markers, along the southbound lanes of I-5 between Winlock in Lewis County and Castle Rock in Cowlitz County.
Raised pavement markers are small reflective dots on roads. They help drivers see lanes at night or in bad weather and alert drivers if they start to drift between lanes, according to the release.
A single lane of southbound I-5 between Avery Road and the Toutle River Bridge (mileposts 68-52) will close each night from 8 p.m. to 4 a.m.
