Motorists should allow extra travel time this weekend as another round of lane closures on Seattle’s northbound Interstate 5 for repaving is expected to cause major delays.

Crews working for the Washington State Department of Transportation will reduce northbound I-5 to two lanes between the Swift Avenue/Albro Place offramp and Highway 520, from 8 p.m. Friday to 5 a.m. Monday.

Traffic will move onto the I-5 collector distributor.
