The pavement on this stretch of State Route 99/Aurora Avenue North is showing its age with ruts and cracks, which can lead to potholes. Asphalt is generally only intended to last 15 years. This area was last paved in 1999. Sections of asphalt have been repaired, but the surface continues to deteriorate. Up to 40,000 vehicles use this major route through north Seattle daily.

During this two-year project, WSDOT contractor crews removed old asphalt and repaved 7.6 miles in both directions of SR 99 between Roy Street and North 145th Street. Dozens of curb ramps were rebuilt or added to provide better sidewalk connections for people of all abilities.

The George Washington Memorial (Aurora) Bridge was also resurfaced as part of a separate bridge painting project.

Needs & benefits

  • Safety: Improving the highway surface eliminates and helps prevent future potholes, cracks and wheel ruts where water can collect. This gives drivers a safer, smoother ride. Reconstructed and new curb ramps create better sidewalk connections for people of all abilities.
  • Economic/Preservation: Repaving this section of SR 99 preserves the highway structure and reduces the need for costly emergency repairs.


  • March 2018: Project was advertised for competitive bidding.
  • May 2018: Project was awarded to Icon Materials.
  • July 2018: Construction began.
  • Winter 2020: Construction is scheduled to be complete.
