May 18 open house will provide details, take public feedback

The public is invited to review and comment on several recommendations to reduce congestion on Interstate 90 through Spokane during an open house Thursday, May 18

I-90 in the Spokane area through the Idaho border is experiencing increased, regular congestion, primarily during peak commute hours. Congestion outside of peak periods is also on the rise. This congestion increases the possibility of collisions on the freeway. 

The open house will share the results of the Interstate 90/Four Lakes to Idaho Operational Study and take public comment about options identified to address congestion and improve safety. Washington State Department of Transportation staff will be available to answer questions.

Open house details

When:  4–7 p.m., Thursday, May 18

Where: East Central Community Center Gym, 500 S. Stone St., Spokane

Details: There will be no formal presentation, people can stop by anytime during the open house.

WSDOT hired engineering firm DKS Associates to study improving safety and operations of the existing freeway without high-cost lane or roadway expansions. The study emphasized low-cost strategies to efficiently move traffic on the existing system while improving safety and addressing transportation deficiencies. DKS used collision history and operational performance to develop several recommended strategies:

  • Active traffic management (using overhead signs to provide advance notice of congestion as well as reduce speed limits when needed)
  • Ramp metering
  • Time-of-day or permanent ramp closures
  • Wrong-way driver notification
  • Traffic incident management strategies
  • Work zone management.
