The paving project from Frostad Road to Sharpes corner began Monday and will include five nights of full closures for Deception Pass and Canoe Pass bridges in mid-July or August.
The project is expected create substantial traffic delays as contractor crews repave four sections along the highway for the state Department of Transportation.
Workers will begin at Frostad Road 8 p.m. June 8, and work their way north.
Contract crews are expected to complete all of the work between 8 p.m. and 6 a.m. with single lane closures to reduce impact on traffic, according to Tom Pearce, spokesperson for state Transportation.
During the entire project, work won’t be done on Friday or Saturday nights, Pearce said.
Starting at Frostad, crews will work their way north, completing the paving work on the roadway sections before tackling the two bridges. Crews will grind off pavement and lay down two inches of new asphalt.
Each section is expected to take one to two weeks to complete, Pearce said, but all work is weather dependent.
Work crews will also place new pavement markings on the bridges, replace joint seals, repair bridge decks and complete erosion control work.
The 10-hour closures will occur 7:30 p.m. to 5:30 a.m., Sunday through Friday. Precise dates of the overnight closures at Deception Pass Bridge won’t be set until 10 days before the bridge paving begins, which will be the final leg of the project.
The bridges will be open for all traffic 5:30 a.m. to 7:30 p.m. on those days.
