Status

Project Complete - July 2009

Construction started May 11 and was complete July 31, 2009.

The NCR Seal 2009 project was consolidated with this project to improve efficiencies and to reduce traffic impacts during construction.


This Collision Prevention, Safety Improvement project installed guardrail where needed and removed roadside hazards along SR 20 between Mazama and the Aeneas Valley, east of Tonasket in Okanogan County. 

Why is WSDOT installing guardrail and removing roadside hazards on SR 20?
This section of SR 20 had been identified as having a high number of injury-producing collisions involving vehicles leaving the roadway.

The End Result
This project improves safety by providing more protection from roadside hazards and steep shoulders.

Project Benefits
This project improves safety and reduce the severity of off-road accidents by:

  • Providing a higher level of protection for errant drivers with new guardrail.
  • Reducing collisions by removing roadside hazards.
