Summer 2021 Project Status

Pre-Construction Update, June 2021

PCL Construction is currently doing pre-construction surveying and utility work for the 16th Street Mall Reconstruction project between Blake Street and Broadway. As part of the pre-construction activities, PCL is performing geotechnical boring work, which will require short-term closures to sidewalks and transitway at some locations along the 16th Street Mall.

  • Partial sidewalk closures will be in place for no longer than half a day. 
  • Business and sidewalk access will be maintained.

To date, PCL has completed approximately 100 out of nearly 900 potholes and has completed potholing activities at three intersections (Blake, Lawrence, and Champa streets) and along three Mall blocks (Blake to Market; Lawrence to Arapahoe; and Champa to Stout). As a reminder, completing this early work will lessen the chance of encountering utilities during construction and is another integral step in the design of this project. 

Work Hours: Monday–Saturday, 8 a.m. to 5 p.m.


  • One lane of traffic in each direction will remain open during these activities. There will be minor delays to RTD's Free MallRide in various active work zones. 
  • Work is estimated to impact two blocks at a time along the Mall. 
  • All work is weather dependent and subject to change.

February 2020 Open House

May 2019 Environmental Assessment Public Meeting

Members of the public were invited to attend public meetings to provide input on the project and EA conclusions. The same information was presented at two meetings on May 1, 2019.

FTA and the project partners reviewed and considered all comments. All comments received during the comment period will be part of the project record. Responses to all substantive comments (those that raise specific issues or concerns regarding the project or EA process, suggest new alternatives, or question or raise concerns over new impacts not addressed in the EA) will be included in the final decision document.

March 2018 Open House

On March 8, 2018, the city and RTD hosted open houses where the public could learn more, ask questions and give input on future refinement of the design. Review the open house materials:

Environmental Assessment

December 2019: Denver Receives Federal Approval to Advance Reconstruction of 16th Street Mall

Denver’s plan to reconstruct the 16th Street Mall took a major step forward with the completion of the project’s environmental phase. The City and County of Denver and project partners the Federal Transit Administration (FTA), Regional Transportation District (RTD), Denver Urban Renewal Authority (DURA), and Downtown Denver Partnership (DDP) will next initiate the process to select a design/build contractor to reconstruct the 16th Street Mall including gathering feedback from the community on key components of the reconstruction process. Read the full release »

Project Background

The ultimate goal of the The Mall Experience study is to have people enjoy the 16th Street Mall more: come more often, stay longer. To achieve that, we’re studying mall activity and conducting public outreach to identify ways to help the mall reach its full potential as a welcoming place for everyone, and the heart of a vibrant downtown.

The Mall Experience study builds on years of community input and planning: the 2007 Downtown Area Plan (PDF) and the 2010 16th Street Mall Urban Design Plan (PDF) established a strategic vision for the corridor. Now, we're ready to ask more of the 16th Street Mall.

UPDATED 2017: View the Gehl Report, Small Steps Toward Big Change (PDF) and the 2016 appendix (PDF); and RTD 16th Street Mall survey (PDF).

 Environmental Clearance and Funding

Because the Mall was built in 1982 with federal funds, any potential modifications must undergo a National Environmental Policy Act (NEPA) review and a cultural resources evaluation pursuant to Section 106 of the National Historic Preservation Act of 1966 (NHPA). Initial project funding for the Alternatives Analysis and Environmental Clearance came from Tax Increment Financing (TIF) via Denver Urban Renewal Authority (DURA) and the Federal Transit Administration (FTA). TIF requires that a design project be identified by 2020 and spent by 2022. As approved by voters, 2017 General Obligation Bonds might also be applied. 

Purpose and Need

The purpose of the project is to develop and implement a flexible and sustainable plan for the 16th Street Mall to address deteriorating infrastructure, increase its use as a gathering place, and improve pedestrian and vehicle safety, while continuing reliable two-way transit shuttle service within the Mall and honoring the Mall’s past and future. Improvements are needed to:

  • Increase opportunities for public use of the Mall as a destination for leisure, commerce and tourism
  • Address deteriorating infrastructure to allow reasonable maintenance frequency and costs 
  • Improve safety for pedestrians and vehicles 
  • Maintain mobility for desired transit operations and for all users
