High-Crash Corridors
High-crash corridors: I-70, the Business Loop, North Avenue, and Horizon Drive
Grand Junction is the largest city on Colorado's Western Slope, and its busiest corridors carry serious injury risk when a driver is not paying attention. Interstate 70 is the main east-west corridor through the city, connecting to Denver via Glenwood Canyon. The I-70 Business Loop runs through downtown on Pitkin Avenue eastbound and Ute Avenue westbound, with US 6 and US 50 running concurrent before US 50 turns south across the Colorado River at 5th Street. State Highway 340 (Broadway) connects Grand Junction to Fruita and the east entrance of Colorado National Monument. Data compiled for the Mesa County Safety Action Plan recorded 19 injury crashes at North 12th Street and Patterson and 18 injury crashes at North Avenue and 7th Street during 2024 and 2025 alone. Horizon Drive has been documented as the site of multiple serious and fatal crashes. A driver who can manage inattention on a quiet road cannot at these speeds and intersection volumes.
