About the Project

Commerce City is proposing the Rosemary St. Widening Project between East 86th Avenue and East 81st Place. The city is evaluating the environmental and right-of-way impacts for the improvements and will develop preliminary and final design along this 0.6 mile stretch. This project compliments widening and improvements to the E. 88th Avenue and Rosemary St. intersection being completed as part of the City’s E. 88th Avenue Improvements Project.

The Rosemary Street project was identified as a priority improvement in the city’s recently-adopted Irondale Neighborhood and Infrastructure Plan, with partial funding already identified in the city’s five-year Capital Improvements and Preservation Plan.
