Plan extra time along CO 105

Construction begins Monday, Oct. 31 on safety improvements

Posted on October 24, 2022 2022Breaking NewsTransportation


Give yourself an extra 15 minutes if you travel CO 105 (Perry Park Road), starting Monday, Oct. 31. Construction will begin on safety improvements as part of the Perry Park Road Traffic Safety Improvements Project.

The Colorado Department of Transportation and Douglas County are partnering on this project, which stretches 18 miles of CO 105 between the Douglas/El Paso County Line and Wolfensberger Road in Castle Rock.

Starting Monday, Oct. 31, crews will install rumble stripes along the middle and sides of the road to alert drivers when they are tracking outside of the travel lane. A future phase of this project will include paved shoulder widening and guardrail installation at the curves near Red Rock Drive.

Based on feedback from the bicycle community, new signs will be installed that remind drivers of the “three-foot” law, requiring motorists to give bicyclists at least three feet of space between the widest part of their vehicle and the widest part of the bicyclist. These signs are expected to be installed this year.

What to expect during construction:

Construction is expected to wrap up by the end of the year.

The $2.1 million project is being funded by a Federal Highway Safety Improvement Program grant, with a 10% funding match from Douglas County.

A safe and accessible multimodal transportation network is one of the Board of County Commissioner’s six core priorities. Read more about the County’s transportation initiatives online.
