I-90 - US 2 Garden Springs to Broadway Ave - Ramp Meters

Project news

Traffic may soon move a little more smoothly around Spokane with the help of a new ramp meter that will manage the flow of vehicles merging onto I-90. Currently, one ramp meter is installed as drivers head north on US 195 and merge onto eastbound I-90. Five new ramp meters are set to go to ad fall 2019. Construction is expected in 2020. Locations for eastbound I-90 ramp meters include:

  • Walnut St.
  • Monroe St.
  • Division St.
  • Hamilton St.
  • US 195 - constructed and will be operational spring 2019

Westbound I-90 on ramps include Division (Browne) St. only.

The Washington State Department of Transportation (WSDOT) will activate a new ramp meter at several interchanges where traffic routinely slows to a crawl during the morning and afternoon commutes and is prone to collisions and “close calls”.  WSDOT plans to activate the new ramp meters in 2020.

“Ramp meters are a proven, cost-effective approach to reducing freeway congestion and collisions, and provide drivers a better, more reliable trip,” said WSDOT Assistant Secretary of Regions & Mega Projects Kevin Dayton.

Needs & benefits

Ramp meters are traffic signals that operate according to real-time conditions on both the freeway and the ramps. They help reduce congestion by providing timed intervals between vehicles, rather than allowing multiple vehicles to enter the freeway at once. Studies show that ramp meters reduce collisions by up to 30 percent.
