Road work will trigger single-lane closures on southbound Interstate 5 between Northeast 179th and 134th today through Thursday.
The lane closures are scheduled daily from 8 a.m. to 3 p.m. for maintenance work by the Washington State Department of Transportation.
Travelers who use southbound I-5 in Clark County should plan ahead for daytime delays.
Work crews will also close the onramp at Northeast 179th Street.
Travelers are reminded to slow down as they approach the work zone, follow directional signs and expect delays, WSDOT said.
