Most Dangerous Corridor
US 34 and the Spaghetti Junction interchange
US Route 34 is Greeley's primary east-west expressway, and its intersection with US Route 85 near Garden City is known locally as Spaghetti Junction, a complex multi-highway interchange with a documented crash history significant enough that CDOT launched a $4 million safety improvement project there. The US 34 corridor also has high-risk intersections at 35th Avenue (a multi-vehicle crash history prompted a roundabout project) and near Weld County Road 17, where high-speed through-traffic mixes with commercial driveways and turning conflicts. Cyclists on or crossing US 34 face some of the highest-exposure conditions in Weld County.
