Various long and short-term infrastructure projects will soon be implemented and require detours along the South Platte River Trail in the coming months and years:
DOTI 8th Ave Bridge
Sept. 27, 2021 – May 2022
Denver’s Department of Transportation and Infrastructure is replacing the 8th Avenue bridge over the South Platte River. This project will close the main trail under the bridge until spring 2022. A detour will be put in place that allows trail users to continue on the trail by using the ramps to cross 8th Ave at street level. The roadway will be closed for construction and there will be no vehicle traffic in the area. It may be beneficial to avoid this area if possible—find resources on planning alternate routes.

Over the next two years, several additional projects will be implemented along the South Platte River Trail that will provide an improved experience for all trail users, with wider concrete surfaces and adjacent crusher-fine trails:
Johnson Habitat Park to W Mississippi Ave:
The failing retaining wall at Mississippi Ave. will be replaced, along with upgrades made to the trail in this area. Anticipated construction timeframe is April-December 2022.
Virginia Ave. to W. Bayaud Ave:
In partnership with CDOT, Denver Parks and Recreation is designing trail improvements as part of a bridge replacement project. The concrete trail will be widened to 12-feet with a 4-foot-wide crusher fines trail alongside it. Construction is anticipated to start in 2023. More details will be provided as they become available.
Alameda Ave. Bridge:
CDOT will be replacing the Alameda Avenue bridge over the South Platte River and Trail. This project will rebuild the trail under the bridge to meet the new regional trail standard of a 12-foot wide concrete trail with an adjacent 4-foot crusher fines trail. Learn more about this project.
River Mile Development:
This long term, mixed-use development plan includes improvements to both the river and trail. The initial phase is anticipated to begin in early 2022 and will reconstruct the existing trail on the east bank of the South Platte River, bringing it to the new 12’ wide standard for regional trails. The general project area is W. Colfax Ave to Speer Blvd. More details on impacts and detours will be provided closer to construction beginning.
DHA Sun Valley Redevelopment:
This Denver Housing Authority redevelopment project along the South Platte River between 9th and 11th Avenue will include a reconstruction of the trail. The exact construction schedule is not yet finalized but is anticipated to begin summer 2022. More information will be provided as it becomes available.
Thank you for your patience as these important infrastructure projects are implemented. Please use extra caution when following detours.
