I-90 Spokane Ramp Meters - Complete June 2023

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.

On April 9, 2019, the first ramp meter was activated at the ramp from northbound US 195 to eastbound I-90.

Since its activation, five more ramp meters have been activated throughout Spokane in 2021. Locations include:

• Walnut/Maple Street to eastbound I-90
• Monroe Street to eastbound I-90
• Browne/Division Street to eastbound I-90
• Browne/Division Street to westbound I-90
• Hamilton Street to eastbound I-90

Several more ramp meters are expected to be activated in 2023 including from eastbound US 2 to eastbound I-90 and from the Geiger/Grove interchange to eastbound I-90.
