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

Project news

The contract was awarded to Northeast Electric LLC on January 16. Construction began May 12.

During construction, each ramp will temporarily close for a period of three days up to one week. Only one ramp will be closed at a time for the construction of the ramp meter.

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 will be constructed 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.


Constrction began May 12 and will last into the fall.
