High-Injury Corridors
C-470, US-85, I-25, and the Lucent Boulevard interchange
The crashes that produce spinal cord injuries in Highlands Ranch most often happen on the community's three primary freeway corridors. C-470 (State Highway 470) runs along the northern edge, connecting US-85 to I-25 in Lone Tree, with the Lucent Boulevard interchange serving as the high-volume gateway to Highlands Ranch Town Center. US-85 (Santa Fe Drive) runs along the western edge, and the South Broadway and C-470 interchange has been identified by the Douglas County Sheriff as the number-one most dangerous intersection in Douglas County. I-25 runs just east of Highlands Ranch through Lone Tree, where the Lincoln Avenue and RidgeGate Parkway interchange is a documented high-accident location with significant truck traffic. Residential collector roads like Wildcat Reserve Parkway and Highlands Ranch Parkway feed directly into these high-speed corridors, and that mix of freeway merges and local traffic is where catastrophic spinal cord crashes happen.
