Purpose and Need

Project Improvements


  • Replace the West Alameda Avenue bridge over the South Platte River.
  • Reconstruct South Lipan Street from West Alameda Avenue to the north where it ties into South Platte River Drive. The reconstruction will consist of one lane in each direction with a dedicated southbound left turn lane.
  • Close South Platte River Drive north of West Alameda Avenue to West Cedar Avenue and remove the signal on Alameda Avenue.
  • Re-construct a portion of the South Platte River Greenway Trail.
  • Construct a cycle track on the north side of Alameda Avenue between South Kalamath Street and South Lipan Street.
  • Improve the intersection of West Alameda Avenue and South Kalamath Street.
  • Construct a water quality pond to the northeast of West Alameda Avenue and South Lipan Street intersection.
  • Add a new outfall in the South Platte River, from the proposed new water quality pond.
  • Modify the existing water quality pond to its ultimate capacity located to the south of West Alameda Avenue and west of I-25.

When construction is complete, pedestrian and bicycle access on both sides of this heavily used corridor will be restored. This means all barriers preventing pedestrians and bicycles from using the south side of Alameda Avenue to cross between South Lipan Street and South Kalamath Street will be removed. 

NOT included in this project currently, due to lack of funds and other potential options, is the West Alameda Avenue to northbound I-25 ramp.
