Denver is launching a new series of traffic safety measures on South Colorado Boulevard to reduce vehicle speeds and prevent accidents. These changes arrive as the city works to address 94 traffic deaths recorded in 2025.
Why it matters
The city is accelerating safety efforts on high-crash corridors to advance its Vision Zero goal of eliminating all traffic-related fatalities by 2030. These adjustments aim to lower the frequency of collisions on stretches of road that have seen high annual crash rates.
The intersection of Colorado Boulevard and Mississippi Avenue recorded 67 crashes between 2020 and 2024. Officials are currently executing engineering modifications to address these figures, with further camera-based enforcement pending in 2027.

DOTI is currently installing electronic speed feedback signs, modifying traffic signal cycles, and replacing flashing yellow arrows with protected green arrows. These infrastructure updates are designed to streamline traffic flow and reduce speeds along the corridor between Mississippi and Iliff Avenue.
Timeline

Legal Context
These improvements are aligned with the Vision Zero initiative, a global movement adopted by Denver to eliminate traffic deaths and serious injuries by 2030. The city is shifting from reactive management to proactive infrastructure redesign to meet this legislative target.
Drivers on South Colorado Boulevard should expect altered traffic signal patterns and new speed warning signs effective immediately. These changes are intended to prioritize safety, but commuters may experience different traffic flow timings as the corridor is synchronized.
The takeaway
The city is prioritizing infrastructure updates to curb high crash rates on major arterials before introducing automated enforcement. Residents should stay alert for new signage and signal configurations along the Colorado Boulevard corridor.
What happens next
The city expects to begin the installation of speed enforcement cameras in the first quarter of 2027.
