The Colorado Department of Transportation (CDOT) has scheduled a public open house to discuss recommended alternatives for the I-25 Speer and 23rd Bridge and Interchange Project. The event will take place on Monday, Aug. 25, from 4 to 7 p.m. at CDOT Headquarters, located at 2829 W. Howard Place in Denver.
The proposed alternatives aim to improve safety, traffic flow, and bike and pedestrian facilities in one of Denver’s busiest areas. CDOT is seeking feedback from the public and community members as part of the project study.
The open house will use a display format where attendees can review project boards and other information. Project team members will be present to explain details and answer questions. Spanish translated materials will be provided.
Free parking is available in Lots M1 and M2, located north and east of the CDOT building. Public transit users can access the site via Decatur-Federal Station, and bike racks are near the main entrance.
Those needing special accommodations such as Spanish or ASL interpretation services or ADA support are asked to contact the project team at [email protected].
An online public comment period will also be available through the I-25 Speer and 23rd Bridge & Interchange Project website from Friday, Aug. 22 to Friday, Sept. 5.
CDOT is currently studying options for replacing aging bridges at Speer Boulevard and 23rd Avenue over I-25 in Denver. In addition to bridge replacement, possible improvements to the interchange system are being evaluated for benefits to all travelers and nearby communities.
During the meeting, CDOT plans to present its combined Proposed Action: implementing both the 23rd Avenue Braid design and a Speer Boulevard Diverging Diamond Interchange. These proposals will undergo evaluation under the National Environmental Policy Act (NEPA) process alongside a “No Action” alternative that would leave current infrastructure unchanged. Public involvement is expected throughout this process.
According to CDOT, “The 23rd Avenue Braid alternative balances the needs to improve safety for all users and maintains access to businesses, community resources and neighborhoods.” The design features a braided ramp layout intended to address multiple transportation requirements.
