Yale Roadway Improvements at Holly

Project Status: Planning, Design and Pre-Construction - Construction is anticipated to begin in 2025.

E. Yale Avenue is a critical east-west arterial in southeast Denver, crossing through and serving City and County of Denver (CCD) and Arapahoe County residents. Yale Avenue near the E. Yale Avenue/S. Holly Street intersection experiences significant congestion and the traffic signal infrastructure is dated. The High Line Canal Trail is a major regional trail facility used for both recreation and commuting that crosses Yale Avenue just west of the E. Yale Avenue/S. Holly Street intersection without a safe connection. Improvements are needed to provide safe and convenient travel for all types of travelers.

The City and County of Denver’s Department of Transportation & Infrastructure has completed the majority of the High Line Canal Trail Underpass Project at Parker Road and Mississippi Avenue.  This new connection offers users a safer alternative to the previous trail which had pedestrians crossing at the busy intersection of Mississippi Avenue and Parker Road.
