W. 8th Avenue Over South Platte River Bridge Replacement

Small location map for W. 8th Avenue Over the South Platte Bridge Replacement Project

The City and County of Denver plans to remove and replace the existing 8th Avenue Bridge over the South Platte River. The 92-year-old bridge has exceeded its design life and needs to be replaced to ensure traveler safety and multimodal mobility. In addition, the existing bridge only accommodates vehicles despite the growing need to accommodate pedestrians and bicyclists.

The $10.8 M project is being funded through the Elevate Denver bond program (approved by voters in 2017). This critical project will enhance and modernize the transportation infrastructure in the area by adding a bridge with wider travel lanes, an additional eastbound through travel lane, and multi-use sidewalks on both sides of the bridge. Connections to the South Platte River Trail will be enhanced to provide an important regional link for recreation and commuting.


Improvements Include

  • Replacement of the 8th Avenue bridge over S. Platte River
  • Widening the bridge to add a second eastbound through lane
  • Adding 10-foot wide sidewalks on both sides of the bridge
  • Adding pedestrian lighting on the bridge
  • Upgrading and improving curb ramps at pedestrian crossings
  • Widening the S. Platte River Trail under the bridge and replacing trail ramps leading up to the bridge
  • Adding trail connection through Frog Hollow Park to 8th Avenue
  • Upgrading/replacing the traffic signal at 8th Avenue and Zuni
  • Improving aesthetics and safety with new retaining walls

Project Benefits

  • Increases comfort and safety for pedestrians and bicyclists
  • Improves access to S. Platte River Trail for recreating and commuting
  • Eliminates need for abrupt lane changes to reduce crashes
  • Enhances driver comfort through wider lanes across the bridge
