Post Street Bridge Replacement

The goal of this project is to retain the historic look of the bridge. When complete, the bridge will have one northbound lane for vehicle traffic as well as pedestrian and bicycle routes. It will also support the Centennial Trail. The bridge also will continue to support a major wastewater interceptor line.

Upcoming Construction in 2022

Summer 2022:

  • Construction of the architectural earth retaining wall on the north side of the bridge will be completed this spring. Huntington Park will provide a great view of this.
  • Sewer flow from the existing sewer pipe will be switched over to the newly installed sewer pipe. This work is ongoing from late winter.
  • The existing sewer pipe on the upstream side of the bridge will be dismantled, along with all associated supporting structures.
  • New superstructure column construction will be completed by the beginning of summer.
  • Bridge deck girder set will take place this summer.

Bike/Pedestrian Detour Routes

The bridge is currently closed to pedestrian and bicycle traffic. To reach downtown from the north bank of the river, pedestrians and bicyclists will need to travel across the Monroe Street Bridge or the Howard Street Promenade in Riverfront Park. Parking in Riverfront Park lots on Post Street and at the northwest corner of Summit Boulevard and Lincoln Street also will be impacted by the bridge construction and additional construction in Riverfront.

The below map shows the construction areas in Riverfront and for the Post Street Bridge and provides information on pedestrian and bicycle routes through the area.

The 333-foot-long Post Street Bridge was built in 1917, spanning the Spokane River between its two sets of magnificent falls. The bridge is a reinforced concrete open spandrel deck arch bridge. After more than 100 years of use, the bridge is in need of replacement.

In May 2019, the Post Street Bridge was closed to all vehicular traffic, following a structural analysis that determined the bridge could not safely continue to carry those loads. Since that time, the bridge has been used exclusively by bicyclists and pedestrians.
