Safety Message
This is an active construction zone. Please drive posted speeds, watch for crews and equipment, and avoid distractions behind the wheel.
Winter is here! Make sure your car is winter-ready, give yourself plenty of time to get to your destination, allow for extra space between you and the car in front of you and keep a safety kit in your car for emergencies.

We appreciate your patience and cooperation as we continue improving County Line Road. Before heading out, check your navigation app for real-time conditions and allow extra time to reach your destination.
Construction hours are Monday through Friday, 7:00 a.m. to 7:00 p.m. Saturday work is possible if approved by the Douglas County Engineer.
Beginning in early January of 2026, motorists should anticipate a full closure of County Line Road from Clarkson Street to the U-Haul business access area. The closure will last approximately 100 days, giving crews time to import dirt for construction at Lee Gulch. Business access will be maintained via County Line Road. Residential access to Clarkson Street will be maintained via Dry Creek Road. More information regarding this closure will be available later this year – stay tuned to our communications.
Total Project Duration: About 24 months.
