On Tuesday, WSDOT bridge maintenance crews will close southbound I-5 at Exit 22 for Dike Access Road just north of Woodland, to check the condition of the bridge using a chain drag test

WOODLAND – Travelers on southbound Interstate 5 in Cowlitz County should plan for a full closure of the highway.

On Tuesday, May 6, Washington State Department of Transportation bridge maintenance crews will close southbound I-5 at Exit 22 for Dike Access Road just north of Woodland, to check the condition of the bridge using a chain drag test.

During testing, crews will pull a chain across the concrete surface and listen for changes in sound. A dull or hollow sound can mean the concrete is coming apart underneath. A clear, ringing sound means it’s strong and in good condition. These inspections help make sure the bridge is safe and structurally sound.

To reduce delays, travelers will follow a short detour using the off- and on-ramps at Exit 22.

What to expect

• Tuesday, May 6: All southbound lanes of I-5 will close between mileposts 24-22 at Dike Access Road, between 11 p.m. and 4 a.m.
• Note: A second closure of southbound I-5 may be needed to give crews more time to inspect the entire bridge deck.

For everyone’s safety, travelers should slow down through the work zone, stay alert, and follow directions from the maintenance crew.
