Adams County CoVid-19 Response and Recovery

120th Avenue Corridor Study

Menu

Thank you to those who were able to join us for the second public meeting. The materials from that meeting can be found via the links below. Please share these with neighbors and friends. 

What is being shown in the alternative images? 

  • These alternatives show how the roadway could be reconstructed to improve safety and access for all travel modes.
  • They show a single location on 120th Avenue but the same or similar improvements would be made to the roadway east and west of the location shown.
  • The viewpoints at Chambers show how the roadway could be changed between Tower Road & Sable Road.
  • The viewpoints at Southgate show how the roadway could be changed between Sable Road & Highway 85.
  • Using your input and other data, the project team will develop a draft concept design. We will share this with the community for review and input in the next 3-4 months.
  • Thanks for sharing your opinions! If you’ve not done so, please sign up for project notifications.

Description, Goals, and Outcomes

120th Avenue is a key corridor for Adams County, City of Brighton, City of Commerce City, and the region. It is critical for many different users, including:

  • Students and parents accessing the schools
  • Residents with limited ways of entering or exiting their community
  • Heavy trucks delivering freight
  • Bicyclists and pedestrians that are forced to share the road with heavy trucks
  • Those interested in accessing community resources
  • Commuters traveling to local and regional destinations

Developing a cohesive vision for the corridor is the first step to improve safety, function, capacity, and reliability for years to come. That vision must accommodate existing and future development, and balance traffic demand while not compromising safety. The vision will inform design recommendations and strategies for implementation.

The study area includes Adams County, City of Brighton, and City of Commerce City, as shown in the map.

Commerce City Project

The City of Commerce City is currently in the process of soliciting contractor bids for roadway improvements between Buckley Road and Chambers Road. This project, estimated to start in 2025, will include construction of widened roadway and related improvements including a median, a sidewalk, and an improved shoulder. The concept design completed for the 120th Avenue Corridor Study will account for these improvements.

In the longer term, the improvements between Buckley and Chambers will not preclude future design and construction of the preferred alternative identified through the 120th Avenue corridor study process.

Survey Outcomes

The community engagement survey was open for 44 days and had 309 participants, over 9,000 data points were collected along with more than 530 comments along the 120th Avenue corridor between US-85 and Tower Road. Community members provided their thoughts and concerns related to safety and mobility along the 120th Avenue corridor. A summary will be shared along with design alternatives at the upcoming public meeting.
