The Colorado Department of Transportation (CDOT) will host a public open house on Monday, Aug. 25, to present recommended alternatives for the I-25 Speer and 23rd Bridge and Interchange Project in Denver. The event is scheduled from 4 to 7 p.m. at CDOT Headquarters, located at 2829 W. Howard Place, Denver, CO 80204, in the ground floor auditorium. Free parking will be available in Lots M1 and M2, and public transit access is provided via the Decatur-Federal Station. Bike racks are also available near the main entrance.
The open house will feature project display boards and information for public review. Members of the project team will be present to explain details and answer questions. Spanish translated materials will be offered. Those needing special accommodations such as Spanish or ASL interpretation services or ADA accommodations are encouraged to contact the project team.
According to CDOT, “The recommended alternatives are proposed improvements to safety, traffic flow and bike and pedestrian facilities in this highly congested area of Denver. CDOT is seeking public and community input on these alternatives as part of the project study.”
An online public comment period will run from Friday, Aug. 22 to Friday, Sept. 5 through the I-25 Speer and 23rd Bridge & Interchange Project website.
CDOT is currently studying options to replace aging bridges at Speer Boulevard and 23rd Avenue over I-25 in Denver. In addition to replacing these structures, CDOT is evaluating further enhancements to improve interchange operations for all travelers and nearby communities.
During the open house, CDOT will present a combined Proposed Action that includes two key elements: the 23rd Avenue Braid and the Speer Boulevard Diverging Diamond Interchange. This proposal will undergo evaluation during the National Environmental Policy Act (NEPA) process alongside a No Action alternative.
As stated by CDOT: “During the public meeting, CDOT will present the recommended combined Proposed Action for improvements: the 23rd Avenue Braid and the Speer Boulevard Diverging Diamond Interchange. This Proposed Action will be evaluated during the National Environmental Policy Act (NEPA) process and will be compared to the No Action which is doing nothing. Public involvement continues through the NEPA process.”
The proposed braided ramp design for 23rd Avenue aims to improve safety while maintaining access for businesses, community resources, and neighborhoods.
