Douglas County began seeking feedback in July on the final gravel stretch of Grigs Road between Highlands Ranch and Castle Pines. Its July 14 update said initial planning was complete and the project was moving into detailed design.
The one-mile phase calls for a 24-foot asphalt roadway, curb and gutter, drainage improvements and a shared-use trail. Plans also include work near curves and slopes, plus a roundabout at the future entrance to Wildcat Regional Park.
The county said road-and-bridge property tax funds would pay for the improvements. Construction was anticipated to start in 2027, while the public comment period ended July 30. The July notice therefore describes a design-stage project, rather than a newly paved route. The trail is intended to connect with the East-West Regional Trailhead and the first phase of Grigs Road work.
