Summer long nighttime lane reductions on southbound I-5 at the Whatcom-Skagit county line begin May 1

BELLINGHAM – A summer-long project to repair and rehabilitate a 12-mile stretch of southbound Interstate 5 near the Whatcom-Skagit county line is scheduled to begin Monday, May 1.

During the project, contractor crews working on behalf of the Washington State Department of Transportation will make repairs along southbound I-5 from just north of Nulle Road near milepost 243 to the State Route 11/Chuckanut Drive interchange at milepost 231 where the pavement is worn and there are cracks, ruts and potholes.

This project will improve the structural integrity of this vital highway by filling cracks and potholes and smoothing ruts. It also will repair and replace several concrete panels and make upgrades to the weigh station at Bow. This work will extend the life of the highway and provide a smoother ride for travelers.

To minimize traffic congestion during construction, most of this work will be completed during nighttime single-lane and ramp closures.
