Project Update

Update: Both Temporary Road Closures (listed below) will re-open on Thursday, May 26, 2022.


  • 90-Day Temporary Road Closure March 1 to May 26 Moore Road between Waterton Road and Denver RV access for construction of a portion of the Waterton Rd Extension. Click on the image below to view a map of the closure and detours.
  • Additional Temporary Road Closure May 17 to May 26, at the intersection of Waterton Road and Moore Road that serves Plum Valley Heights subdivision and those who live south of the Public Works Operations blue metal building (at 8500 Moore Road). Traffic will be detoured from Moore Road to Waterton Road via the EVOC Driveway. Asphalt will be removed and replaced at this intersection to create the new Waterton Road tie-in.

The need for the extension of Waterton Road to give those in Roxborough Village, Chatfield Farms, Roxborough Downs, River Canyon and Sterling Ranch an alternative to Titan Road as they travel to and from US Highway 85 is identified in the County’s 2040 Transportation Master Plan.

Waterton Road – Phase 1 & 2 and Turn Lanes on Airport Road – Rendering

Phase 2 – current phase

Phase 2 of the project was approved by the Board of County Commissioners, in partnership with Sterling Ranch Community Authority Board (CAB) and the Sterling Ranch Development Company. The completion of this roadway project will provide much-needed secondary access into the Chatfield Basin along with additional roadway capacity and a more reliable transportation network. Phase 2 anticipated construction costs are fully funded by Sterling Ranch CAB and Sterling Ranch Development Company for a total of $16,130,082. The County will be responsible for the construction management of the project. Phase 2 of the project is expected to be completed in the fall of 2022.

Phase 1 of the project was completed and open to the public Aug. 7,  2020, and included the construction of a 2.8-mile minor arterial two-lane roadway between Airport Road and Moore Road, four bridges, drainage facilities, and fencing. There are four bridges on the Project that were designed for elk crossing since the roadway crosses the County’s major wildlife corridor between the Pike National Forest and the Highland Ranch OSCA. There are two, single-span bridges and two, three-span bridges. The Indian Creek Bridge on the east end of the project has a total bridge length of 410 feet. The completed roadway will have two 12-foot lanes with paved shoulders.
