High-Crash Corridors
High-crash corridors: US 287, SH 7, and SH 42
Three state-designated routes carry the bulk of Lafayette traffic, and distraction turns each of them dangerous. U.S. Highway 287 is the main north-south arterial through the city, and CDOT and Boulder County initiated safety improvements on the corridor in 2019 because of the frequency of collisions there. State Highway 7 runs as Arapahoe Road west of US 287 and Baseline Road east of US 287, passing directly in front of Centaurus High School. State Highway 42 runs as 95th Street along the city's eastern edge. A driver who can manage inattention on a quiet road cannot at these speeds, this close to a school zone.
