Work begins later this week on a major rehabilitation project on Interstate 5 through King County.
Over the next three years, state contractors will replace expansion joints and broken concrete panels and do some repaving on 22 miles of northbound roadway from Kent to Northeast Seattle.
Most of the work will be done at night, but officials at the Washington State Department of Transportation warn that there will be some weekend lane closures, when two or more lanes are closed.
The first phase of construction starts this spring between South 200th Street in Kent and the Duwamish River bridge in Tukwila.
WSDOT says the dates of those northbound lane closures have not yet been chosen.
The second phase starts this summer in Seattle, between Martin Luther King, Junior Way and Ravenna Boulevard.
