Needs & benefits

Overview

Contractor crews will remove old asphalt and repave 7.58 miles of State Route 99/Aurora Avenue North between Roy Street and North 145th Street in Seattle. In addition, dozens of pedestrian ramps will be rebuilt or added to provide better sidewalk connections for people of all abilities.

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

Why is WSDOT paving SR 99 between Roy Street and North 145th Street?
The pavement on this stretch of SR 99 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.

What should drivers expect?
While most of the work can be completed through nighttime lane and cross street closures, some daytime lane closures are needed for pedestrian ramp work.

The End Result

This project will provide drivers with a smoother, safer ride on SR 99. New pavement will preserve the life of the roadway and reduce maintenance needs. Reconstructed and new sidewalk ramps will create better sidewalk connections for people of all abilities.

Project 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 sidewalk ramps create better sidewalk connections.
  • Economic: Paving reduces the need for emergency pavement repairs, which are costly to taxpayers and can cause additional congestion during peak commute hours.
