University District Pedestrian/Bicycle Bridge
University District Pedestrian/Bicycle BridgeSpokane, WA
Date Completed: Summer of 2018
The University District Pedestrian/Bicycle Bridge is the first Infrastructure project within the (UDSC) University District-Sprague Corridor and will likely serve as the beginning of the redevelopment envisioned for the area. The project has several funding sources which will be managed by the City of Spokane. Construction began in March of 2017 and be completed for use in the summer of 2018.
The Innovative design performed by KPFF Consulting Engineers, Seattle, WA, provides a 460’ long bridge. The Structure is highlighted by the 120’ tall center Arch Pylon and cable stayed spans of 240’ and 170’ providing access over the Burlington Northern Santa Fe Railway and Martin Luther King Jr. Way. Each landing provides pedestrians with optional stair or 15’ wide Concrete paved pedestrian ramp access to sidewalks and streets.
The structure offers several challenges including construction of the 120’ tall Arch Pylon. The Arch is positioned between BNSF and MLK Way within a narrow strip of land. The limited space provides crews with access challenges and will require Railroad flagging throughout the construction of the Arch. While Arch construction will be a major focus early on in the project, the remaining substructure will be constructed in anticipation of the Steel girders to be set in 4 segments with the curved span at the North landing being constructed piece by piece.
Once the Steel Girder Segments have been set and the Pylon construction complete the structure will begin to take shape with the steel cable stays stretching across the two major spans. The structure is finished with a concrete Deck with Curb and decorative fencing. Each landing provides pedestrians with decorative retaining walls and landscaping along the pathway.
