Emergency pavement repair work will limit Interstate 5 southbound to just one lane of travel between Northeast 199th Street and the Interstate 5 and 205 split starting Friday night, and work will continue into Saturday morning.
The Washington State Department of Transportation advised drivers to find an alternate route or plan for long delays.
Work is set to start at 10 p.m., and crews will reopen all lanes of the highway at 7 a.m. Saturday, according to WSDOT.
