Work continues on both ends of Whidbey Island’s main highways as the $15 million state project continues repaving nearly 30 miles of road. Although it looks to be nearing completion, finishing work could go on through the summer.

Since April, crews have improved intersections, sidewalks and gutted, grated and replaced large swaths of road, starting at Highway 525 at Bob Galbreath Road in Clinton to Holbrook Road on Highway 20 north of Coupeville.

“Crews are working long hours to get this project done as quickly as possible,” Andrea Petrich, spokeswoman with the Washington State Department of Transportation, said. “Work has been going smoothly and right now we’re on schedule to finish the project this fall, as expected.”

Crews will continue to do overnight work on Sunday through Friday morning, 7 p.m. to 7 a.m., she said. Traffic could be delayed up to 30 minutes in sections north of Coupeville and around Clinton.

For ferry commuters, allowing an extra 30 minutes for travel time is recommended.
