WSDOT crews measure how steep the existing pedestrian ramp is at the corner of Griffin Ave. (SR 164) and Pioneer Street.

Concrete sections of the old highway peek out from beneath cracked asphalt on SR 164. 




Here's the intersection of Watson Street and SR 410 (Roosevelt Avenue), looking south. WSDOT will install a traffic signal in this location.












Status

July 2014

  
  • Closures of eastbound SR 164 may occur daily from 7 a.m. to 5 p.m. Eastbound drivers will follow a short detour around the closure.
  • Pedestrians may find some crosswalk locations are closed around-the-clock while the pedestrian ramps are rebuilt.
  • Check the King County construction update report for all closures related to this project.
  • Sign up to receive email updates about this project and other South King County topics.

Decades of use, combined with abandoned railroad tracks and a section of buried 100-year-old broken concrete, have caused the pavement along 1.5 miles of State Route 164 (Griffin Avenue) in Enumclaw to crack and separate. This summer, crews will repair the state route and repave the roadway for drivers. 

In addition to paving, WSDOT also will upgrade most of the pedestrian sidewalk ramps on the route, and install a new traffic signal at the intersection of SR 410 and Watson Street North.


Why is WSDOT repaving SR 164 through Enumclaw, upgrading the pedestrian ramps and installing a new traffic signal?


Repaving

  • This section of roadway was last paved in 1998. The pavement is broken and cracked in many areas.
  • Cracked and rutted pavement can cause vehicle damage if not repaired or replaced. 
  • Over the years, WSDOT maintenance crews have sealed the large cracks and patched potholes to help hold the roadway together. Now it is time for a longer-lasting fix.

Pedestrian ramps

  • The current pedestrian ramps were last upgraded in the late 1980s and 90s. Since then, guidelines set by the American Disabilities Act (ADA) require a more gradual, less steep ramp from the sidewalk to the street.
New traffic signal at SR 410 and Watson Street interchange
  • Traffic studies show a steady increase in vehicle and pedestrian traffic in this area since 2009.
  • The intersection has now reached the point where a traffic signal with dedicated turn arrows onto SR 410 is needed to preserve safety.

The End Result
To extend the life of the highway and smooth the roadway for drivers, we will:

  • Grind out all of the existing asphalt.
  • Remove buried concrete panels and abandoned railroad tracks.
  • Rebuild the subgrade where needed.
  • Repave both directions between High Point Street and SR 410.
In addition to repaving the roadway, WSDOT will:
  • Upgrade 90 pedestrian ramps to comply with 2014 ADA standards.
  • Install crosswalks and a traffic signal at the junction of SR 410 and Watson Street.

Project Benefits

  • A smoother driving surface
  • Reduced maintenance costs
  • Improved pedestrian and driver safety
