Project overview

The Northwest Region Emergency Pavement Repair project covered 88 locations among 23 communities in King, Snohomish, Skagit and Whatcom counties. The repairs spanned three interstates, 12 state highways and about 20 miles of pavement repair, including four bridge decks.

Completed in summer 2023, travelers can now enjoy a smoother ride that will be preserved for years to come.

What to expect

There were a variety of day and overnight lane closures so crews could make repairs and finish permanent striping. Work was suspended over the winter season but resumed in spring 2023 and wrapped by early summer.

History and background

The winter of 2021 brought a significant amount of snowfall to the northwest region and as a result, the potholes created are widespread and need immediate attention. Governor Jay Inslee signed an Emergency Proclamation Jan. 8, 2022 to fund these repairs.

Potholes can start in cold temperatures when groundwater freezes and expands. Once the ground thaws, it returns to a normal level, but the pavement pushed up during the ground freeze remains raised. This causes a gap between the pavement and the ground. Vehicles traveling over these gaps cause the road surface to crack and fall into that hollow space.
