Who maintains traffic signals in Douglas County?
It depends. Refer to the Signalized Intersection List [Approx. 43KB PDF], or see below. Traffic signals located along state highways (US-85 (Santa Fe Drive), SH-83 (Parker Road) and at most on- and off-ramps to I-25 and SH-470 (C-470), are maintained by the Colorado Department of Transportation (CDOT). The current exceptions are the on- and off-ramps at Quebec/C-470 and Lucent/C-470, which are maintained by Douglas County, and Yosemite/C-470 and Lincoln/I-25, which are maintained by Lone Tree. Traffic signals located within incorporated cities or towns (Castle Rock, Lone Tree, Castle Pines North and Parker) are maintained and timed by the respective local jurisdiction. On unincorporated county roads (including roads within Highlands Ranch and Roxborough communities), Douglas County Traffic maintains the traffic signals. Douglas County Traffic signal maintenance staff is augmented at times with on-call contractors.
