Riverside Bridge Replacement

The City of Fort Collins will be replacing the structurally-deficient Riverside Avenue bridge over Spring Creek in the fall/winter of 2018/19.  The work includes removal of the existing structure, raising the roadway, installing new storm sewer systems, and installing the new bridge and roadway system. 

During bridge construction, a 6-week full closure of Riverside will be required to remove and replace the bridge.  During this time, EPIC parking access will be detoured to Stuart Street. 

Once the bridge work is completed, the City will focus on Spring Creek stream restoration and realignment work that will take place in the Spring Creek corridor.  Limits of the stream rehabilitation work will be from the railroad underpass on the east to the existing Edora detention ponds at the west.  The Spring Creek restoration and realignment work will begin in January and will continue through the end of the Spring 2019.  For more information about the Spring Creek stream restoration project visit: fcgov.com/utilities/spring-creek-at-edora-stream-restoration/.


Overall Project Goals

Primary goals of the project include:

  • Replace the Spring Creek bridge which is currently rated as structurally deficient
  • Raise the Spring Creek Trail so that it floods less frequently
  • Raise Riverside roadway and bridge above the existing Spring Creek floodplain
  • Restore the Spring Creek stream corridor to a natural condition
  • Improve the Spring Creek floodway corridor
  • Improve the aesthetics of the Riverside Bridge
  • Add sidewalk on the east side of Riverside to EPIC
  • Improve Riverside Ave. drainage

Construction Update

The City of Fort Collins Engineering Department and their contractor, Lobos Structures, LLC will begin preliminary construction activities for the Riverside bridge construction during the week of September 10.  The bridge construction project is anticipated to be completed in December2018. 

During September and early October, there will be minor detours to the Spring Creek Trail that will require trail users to use the existing high-water “at-grade” trail crossing of Riverside.  There will also be some traffic flagging operations on Riverside for construction equipment traffic.  During this time Riverside will remain open to traffic at all times.

The full closure of Riverside for the bridge removal and reconstruction is anticipated for mid-October through the end of November.  Exact closure dates have not been determined yet.  The City will release additional information as the construction schedule becomes more defined.
