Hamilton Street Corridor

Safety Improvement Project from Desmet to North Foothills

Construction on the project to improve safety along the Hamilton Street Corridor from Desmet to North Foothills is underway.

The project is designed to make long-desired safety and traffic flow improvements at six intersections, including the addition of dedicated left turn signals.

Here's what's happening:

  • The Hamilton intersections at Mission, Indiana, and North Foothills will get protected left-turn signals (arrows) for all four directions at the intersection.
  • The Hamilton intersections at Sharp and Illinois will get protected left-turn signals for traffic traveling north and south on Hamilton. Traffic turning left onto Hamilton from these streets will yield to through traffic.
  • The Hamilton and Desmet intersection, which currently has a pedestrian-activated rapid flashing beacon, will be upgraded to include a full traffic signal. Protected left-turn signals will be added for traffic traveling north and south on Hamilton. Traffic turning left onto Hamilton will yield to through traffic.

Access to the businesses on the Hamilton Corridor will be maintained. But, the work will impact traffic on this busy north-south corridor, and commuters may want to choose other routes during construction.

Trent Avenue Bridge Replacement

Traffic in this area also will be impacted by a Washington State Department of Transportation Project (WSDOT) to replace the East Trent Avenue Bridge over the Spokane River just to the east of Hamilton. Information on that project is available on the WSDOT web site.

Lane closures for that project will begin in early March, with a full closure expected later to replace the 1910 span. MLK Way will serve as the detour around the bridge replacement project.
