Alternatives Analysis And Environmental Evaluation

The 16th Street Mall, which includes the transit-way and adjacent pedestrian areas, was constructed in 1982. It provides a link between Denver Union Station and Civic Center Station and provides a travel option to those who work and live in the Denver downtown area, as well as the many visitors that come to Denver each year. Today, the Mall, which was designed by I.M. Pei, serves 45,000 passengers on an average weekday.


Since its construction nearly 30 years ago, the Mall’s aging infrastructure has reached its design life span and updates and/or maintenance are needed to ensure the Mall’s continued success. Ongoing concerns with both pedestrian and mall vehicle safety, along with the significant cost of maintenance, have led to the consideration of replacing the transit-way (travel lanes) with an alternative surface.

To consider alternatives, RTD is initiating an Alternatives Analysis and a cultural resources evaluation pursuant to Section 106 of the National Historic Preservation Act of 1966 (NHPA).

2018 Update

On Tuesday, January 23, RTD staff presented to the Board of Directors a plan for the 16th Street Mall that would realign transit lanes to provide more sidewalk space. The plan was developed through a collaboration with the City and County of Denver. View the presentation.
