High-Crash Corridors
High-crash corridors: I-25, US 287, SH-7, and SH-52
Erie's rapid growth has brought construction traffic, new arterial roads, and crowded intersections, and distraction turns each of its main corridors dangerous. Interstate 25 cuts through Erie with an interchange at Erie Parkway, part of the 1,280-acre I-25 Erie Gateway development. US Highway 287 is a major north-south arterial through town; CDOT identified significant safety deficiencies at the US 287 and CO 52 intersection significant enough to fund a full improvement project, including new turn lanes, bicycle lanes, pedestrian ramps, and signal replacement. Colorado State Highway 7 (Baseline Road) is Erie's primary east-west arterial, connecting the town to Boulder, Lafayette, Louisville, and Brighton, with shoulder widening completed near Erie Airport Drive in January 2026. SH-52 ties into the US 287 corridor. Where in Erie the crash happened determines which county's court and which road authority are responsible, but it does not change how dangerous a distracted driver is on any of these roads.
