Why is WSDOT repairing the pavement on northbound and southbound I-5 in Snohomish and Skagit counties?        
The concrete in this section of I-5 is nearly 60 years old in some locations. It is showing signs of deterioration with cracks and wheel ruts from the 85,000 vehicles that use the road each day.

Contractor crews are repairing select concrete panels, replacing seriously damaged panels and grinding the others to get rid of wheel ruts, which can collect water and reduce traction.

Crews will also repave the shoulder and the following freeway on- and off-ramps with new asphalt:

  • 236th Street Northeast
  • SR 532
  • Freeborn Road
  • Starbird Road

Why is WSDOT upgrading sidewalk ramps?
Seven sidewalk ramps in the area need to be upgraded to provide better sidewalk connections for people of all abilities. Crews will reconstruct the sidewalk ramps to provide a more gradual slope which will make it easier to safely cross the street.

What can drivers expect?
During the two-year project, drivers should expect overnight double lane closures, generally between the hours of 10 p.m. and 5 a.m., and single lane closures during the day for concrete repair work.

Expect sidewalk and shoulder closures during daytime hours for pedestrian ramp work.

The End Result

  • Once the concrete panels are repaired, replaced and ground, drivers will have a smoother drive.
  • People of all abilities will have a safer and easier time crossing the street with the new sidewalk ramps.

Project Benefits

  • Safety: This work will provide a smoother drive, free of wheel ruts which can collect water and reduce traction.
  • Preservation: This work will preserve the infrastructure for years to come. It will also reduce the need for costly emergency repairs.
