39th Avenue Greenway & Open Channel

With this project, Denver Public Works will create a new 12-acre recreational greenway with a multi-use trail between Franklin and Steele streets while reducing flood risk to nearby homes and businesses.

The historic Montclair basin is the largest in Denver with no natural drainage. Instead of floodwater flowing through the historic Montclair creek, which was built over in the early 1900s, water runs through neighborhood streets. This project will replace the city's aging infrastructure with green infrastructure that can better control stormwater and improve public safety and water quality. In addition to protecting neighborhoods from damaging floodwaters when storms hit, the greenway will provide other neighborhood benefits that will be enjoyed year-round. The greenway will stay mostly dry, and convey water only in storm events.

As of mid-September, the project is approximately 60% complete.

  • Approximately 140,000 cubic yards of earth have been removed from the greenway channel for pipe excavation 
  •  70,000 cubic yards of earth was placed on the northeast side of the project connecting 40th Avenue to Monroe Street. 
  • About 6,500 linear feet of box culverts and pipes have been installed for flood water management.
  • Roughly 2,260 cubic yards of concrete was poured and 647,856 pounds of reinforced steel (rebar) was placed on various structures throughout the project, including the York Street bridge, which is now 85% complete. 
  • The project also reopened 40th Avenue between Madison and Monroe Street. This work included the removal of the existing bridge, placement of approximately 20,000 cubic yards of earth, and installation of 60” concrete storm sewer pipe that was installed 30’ deep and cast-in-place retaining wall. Finally, roadway features such as curb and gutter, sidewalk, asphalt paving, and striping were installed.

Throughout the next three months, the project will advance down the channel with final construction of the Franklin Outfall and will complete excavation of the greenway, which makes way for the installation of multiple walls along the channel.

In addition, 40th Avenue from Columbine to Clayton will reopen and construction will begin on the Williams Street vehicular bridge, the High and Gilpin Street pedestrian bridges, and residential fencing along properties that line the greenway will commence.

On Thursday, August 15, 2019, 40th Avenue from Madison to Monroe was reopened to traffic, including motorists and pedestrians.

Since the closure in April 2019, the following work was completed:

  • New stormwater pipe installed
  • Bridge removed
  • 90,000 cubic yards of new dirt added to level the ditch
  • Built in a new road in place of the bridge 

Construction on the 39th Avenue Greenway project continues to progress as scheduled. As of mid-April, the project is 30% complete. Milestones reached include:

  • Started construction of the Franklin Outfall
  • Began construction on the new vehicular bridge over York and 39th Ave.
  • Began construction of the pedestrian bridges along 39th Avenue at High Street and Gilpin Street.
