Past Public Outreach

Watch the virtual public meeting to learn more about future High-Performance Transit on the I-90/Valley Corridor.

The March 2022 survey has closed and the results will be available soon. Read the full press release here.

A second open house occurred on June 14, 2022. View the recording of that meeting here.

STA’s guiding objectives for this project are:

  • Support economic vitality and growth by improving mobility on the busiest urban corridor in the Spokane/Coeur d’Alene Region
  • Advance transportation equity by improving access to jobs, education, health care, recreation, healthy food, childcare, and other facilities
  • Promote integrated solutions that support safe and healthy transportation options for all ages and abilities
  • Engage our local agencies, businesses, and diverse community members to envision, enhance, craft, validate, and support service and facility improvements
  • Serve as a model of cooperation for the community benefits of a regional and interstate partnership
  • Advance service and supporting infrastructure improvements that are safe, cost-conscious, high-performing, resilient, and reflect and enhance community identity and environment     

Regional employment trends present a viable and strategic opportunity for HPT on the I-90/Valley Corridor

Census data has found the pace of growth in employees commuting cross-border (between Kootenai and Spokane Counties) for work is significantly higher than the pace of growth in total jobs during 2009-2018. 

Project Background

This project is one of six High Performance Transit corridors slated for improvements in STA Moving Forward.

Our study will explore possible implementations such as:
  • New transit centers
  • Expanded commuter parking east of Sullivan Road
  • Direct, non-stop peak hour service between Liberty Lake and Spokane
  • Night and weekend service
  • Extend service to Post Falls and Coeur d’Alene on a two-year pilot basis through a cross-state partnership*

*Pilot Program: Introduce service to Post Falls and Coeur d’Alene dependent on collaboration with partners in Kootenai County

Improvements will include design, engineering, right-of-way acquisition, and construction of transit facilities and infrastructure.

Other I-90/Valley Corridor elements:
  • HPT stations/enhanced stops at other locations in the corridor
  • I-90/Valley service architecture
  • Argonne Road flyer station and park and ride
  • Network redesign informed by new facilities
