Trail Projects

Significant gaps exist in our Centennial Trail which inhibit the cohesiveness of Trail travel for its 2.4 million users each year.  Our goal is gap completion — and we have lobbied to get these projects into City and State budgets.  

The Trail Builder’s Fund was created to leverage community donations for projects related to the completion and enhancement of our Spokane Centennial Trail.   Your tax-deductible donations help complete the following projects (listed from east to west):
Centennial Trail gaps will be completed when funding is secured project-by-project.  Help close our Trail gaps with your secure gift today!

Mile 0 – Gateway Park/Appleway Bridge

At the Trail’s Washington/Idaho border, Spokane County has realigned the Centennial Trail; moving the Trail under a new bridge on East Appleway Lane and closer to the river to rejoin the current Trail alignment just past the current visitor center. Project Update:  Gap completed!  The Trail is paved and open for use!  Directional signs have been donated by our Trail Builders Fund.  State line realignment

Mile 9 – Sullivan Road West Bridge Replacement

The west bridge is slated to be rebuilt between spring, 2014-fall, 2015.  Project Update: The Centennial Trail will remain open during most of the project construction period, except for these brief times:

  • When the temporary trail protection structure is being constructed near the beginning of the project and removed later as the project wraps up;
  • When the portion of the West (southbound) Bridge is being demolished directly above the Trail, and;
  • When the precast concrete girders for the new West Bridge are being placed above the Trail.  These girders weigh in excess of 100,000 pounds each. 

When the Trail is closed for construction, Trail users will be routed onto a street level detour.   Orange and black signs will mark the route.  The detour route will have Trail users cross Sullivan Road at the Indiana Avenue traffic signal.  The east terminus of the Trail detour is at the Old Mission Road trailhead.

Mile 13.5-15 – Argonne/Maringo Gap

Following the Trail east from Boulder Beach, the Trail moves onto the shoulder of Upriver Drive for approximately five blocks. Here, the Trail would be re-routed to head north along Maringo Drive for approximately 3/4 mile. At the Argonne Bridge, the Trail would go underneath the new Argonne Bridge; space was provided for this routing during the bridge rebuild. The Trail would move back up to Maringo Drive, and continue east to the Maringo Trailhead. This rerouting would eliminate approximately 2 miles of the Trail route away from busy arterial streets. Project Update:  Spokane County plans include a grade separation from the Centennial Trail.  They are also working with Inland Empire Paper regarding their decision on an easement on the east side of Argonne, which would allow this project to move forward.

Mile 20.5 – Mission Avenue Gap

Crossing Mission Avenue and continuing east on Upriver Drive has been recognized as a safety challenge requiring special design attention.  Mission Avenue is a major east/west four-lane arterial over the Spokane River.  From Mission Park, Centennial Trail users are faced with BNSF railroad track crossing, a challenging pedestrian crossing and a tight right turn to deteriorating sidewalks next to congested west-bound traffic to reach Upriver Drive.
In spring, 2012, the City of Spokane hired David Evans and Associates, Inc., to study the Mission Gap project and present conceptual designs — focusing on a safe, feasible solution for pedestrians to cross the BNSF railroad tracks, Mission Avenue and Upriver Drive as they enjoy the Centennial Trail. The final study has been divided into three phases and endorsed by the City of Spokane Park Board : Phase 1 – Surface Improvements (separating the trail from the parking lot through Mission Park, separating the trail from the roadway along Mission Avenue adjacent to the Avista campus and improving visibility and functionality of the pedestrian refuge island within the Mission Avenue crossing at Perry Street). Phase 2 – Trail bridge over Mission Avenue Phase 3 – Trail tunnel under the BNSF tracks in Mission Park. Project Update:  The Spokane Regional Transportation Council has funded $443,250 for Phase 1 “Centennial Trail, Mission Avenue Gap – Surface Improvements,” with Friends of the Centennial Trail committing $18,500 in matching funds.  The project will be completed in 2017.  Timelines and details will be posted here as they become available.  We thank the City of Spokane and the Spokane Regional Transportation Council for their support! Concept images and overviews are posted here on the City of Spokane Engineering Services webpage.  Learn more:  Getting There: Bridge best choice for Centennial Trail crossing at Mission

Mile 22 – Spokane Convention Center Expansion

Project Completed!  From the Division Street Bridge west to the King Cole Bridge at the Spokane Convention Center, the Centennial Trail has reopened!  Like the newly discovered Spokane River Gorge views from the Trail at Kendall Yards, the “new” Convention Center views show case Riverfront Park, the north bank of the river and Gonzaga University like never before. Extensive work to restore and landscape the Spokane River shoreline is beautiful.  The addition of over 75 trees and hundreds of native plants make this area flourish.  We extend our thanks to Land Expressions, Garco Construction and the Spokane Public Facilities District for their work to improve our Spokane River, Centennial Trail and community!

Mile 23 – Veteran’s Park Gap

To better connect the Centennial Trail from downtown Spokane with the West Central neighborhood to Riverside State Park, the Trail has been re-routed through Riverfront Park and across the the Post Street Bridge.  The Trail turns left at Bridge Street, continues through Veteran’s Park and extends west under the Monroe Street Bridge to Kendall Yards. Project Update:  Gap completed! Veteran's ParkReconstruction of the Veteran’s Park Trail, in concert with the Kendall Yards Centennial Trail project, opened September 27, 2013!  The work was done in partnership with the West Quadrant Tax Increment Finance District (WQTIF), Greenstone Corporation in conjunction with Kendall Yards and the City of Spokane.   

Mile 24 – Kendall Yards Gap

The Centennial Trail at Kendall Yards is a vital “northwest connector” route into downtown Spokane for both recreational and get-to-work commuting. The Centennial Trail provides the framework for an interconnected network of pedestrian-friendly Grand Openingstreetscapes, publicly accessible plazas and open space at Kendall Yards, connecting homes and businesses and providing connections to the adjacent neighborhoods and downtown.  Here, the Centennial Trail features numerous panoramas and incredible viewpoints. Kendall Yards revives the vision of the Olmstead Brothers with the completion of the Great Gorge Park, including the long-awaited extension of the Centennial Trail from Monroe to the Sandifur Bridge and Summit Boulevard to the northwest. Project Update:  Gap completed!  This grand addition of our Centennial Trail is simply breathtaking!  Thank you Greenstone and the City of Spokane for making this dream a reality!  Enjoy!  Read The Spokesman-Review editorial here:  Centennial Trail’s newest section offers river view not seen before.

Mile 25 – Bridge Avenue to Boone/Summit Blvd Gap

From the westernmost border of Kendall Yards at Bridge Avenue, the Centennial Trail descends approximately 50 feet to an abandoned railroad bed paralleling Summit Boulevard. From the end of the rail line, the Trail turns due north, traversingBoone to summit_completededited gently up the hillside toward the intersection of Summit Boulevard and Boone Avenue. Project Update:  Gap completed!  Mile marker 25 is in place where the Trail curves north toward Boone Avenue. The view is fantastic!  Thank you to the City of Spokane for this beautiful new section of Centennial Trail! 

Mile 26 – N. Summit Blvd. to T.J. Meenach Bridge Gap

Following N. Summit Blvd. to Pettet Drive, then turning north onto Pettet Drive (Doomsday Hill) to TJ Meenach Bridge, is the opportunity to improve this existing Centennial Trail route, creating a better, safer bike and pedestrian experience with signage, striping and traffic-calming elements. 

Mile 37 – Carlson Road Gap

Safety calls for moving pedestrians and bicycles away from a sloping, narrow roadway from the Carlson trailhead moving north to Charles Road and Nine Mile Bridge.  Approximately 0.5 miles of Centennial Trail would be realigned away from the main roadway, providing safe separation from motorized traffic on a new 10’ wide section of Trail. Estimated project cost:  $320,000.

Miles 37.5-39 – Nine Mile to Long Lake (Lake Spokane) Trail Extension

This project will be a 1.7 mile extension to the Trail, beginning just north of Sontag Park and running through a beautiful wooded area, ending at the Nine Mile Recreation Area.

Sontag Park Trailhead

Sontag Park Trailhead

Project Update:  Great news!  The 2013 Washington legislature passed the capital budget with $65 million for the Washington Wildlife and Recreation Program.  Included in this funding is $582,000  for the 1.7 mile, 10 foot-wide Centennial Trail extension!  Funding includes a sponsor match of $120,000 (15%) from private funding sources, including Avista and our own FCT Trail Builders Fund; we have $20,000 earmarked for this project.  This extension will be completed by August, 2015.  Thank you to WWRP, Washington State Parks and Recreation, Avista and all community members who rallied support for this important project!
