39th Avenue Greenway

Denver, Colorado

The 39th Avenue Greenway and Park Hill Detention Design/Build project will create a mile of vibrant recreational space in east Denver that integrates into the urban context of the neighborhoods. In addition to providing flood protection, the design for this $78 million project will enhance multi-modal connectivity and improve water quality from an ecological perspective.  Our team is heavily engaged with the community in an inclusive process to improve the aesthetic and visual character of the corridor while respecting its historic industrial context. Through the creation of native natural, active, formal and play zones, the design team is creating a diverse cadence along the trail. Designed for year-round use, amenities include; bridges, low-flow crossings, natural play areas, shade structures, wayfinding, access roads, and specialty areas for events and gatherings.

As the first shared street in Denver that integrates pedestrians, cyclists and vehicles in the same corridor, plazas and urban design features will encourage activation of the greenway as a true multi-use trail. The overall character has a park-like feel, increasing multi-modal access and connecting communities across this stretch of the urban fabric. Clusters of active uses are placed at key nodes and intersections and dispersed along the greenway to provide interest and places to rest, with considerations for visibility, safety and connection. 

The images shown above are initial conceptual models of the project.  Stay tuned for updates as the project continues to evolve.
