High-Crash Corridors
High-crash corridors: US 36, SH 42, and McCaslin Boulevard
Louisville sits at the intersection of US 36 and the Front Range foothills, and distraction turns its main corridors dangerous. US 36, the Denver-Boulder Turnpike, forms the southwestern border of Louisville and carries heavy daily commuter traffic between Denver and Boulder; CDOT records document a 39-vehicle pileup on this stretch and weather-related fatal crashes, with mountain wave downslope winds reaching gusts up to 100 miles per hour that have directly contributed to crashes here. Colorado State Highway 42 runs south from SH 7 through Louisville east to US 287. McCaslin Boulevard at the US 36 interchange, home to a diverging diamond interchange that opened October 19, 2015, is a documented bottleneck and crash concentration point. A driver who can manage inattention on a quiet road cannot at this interchange, in these wind conditions.
