These projects have been completed.
Douglas County’s 2025 neighborhood street paving program in Highlands Ranch includes East Dutch Creek Street, East Millstone Street, East Millstone Place, and South Millstone Court.
There are two other larger construction projects in the Highlands Ranch neighborhood that have different start dates, and you can access information for them here:
Cresthill Lane Resurfacing Project
Venneford Ranch Resurfacing Project
On each street, work will be completed in phases – the first phase consists of sidewalk repairs and curb ramp upgrades, which will be performed by the County’s sidewalk repair contractor. Sidewalk repairs usually take between two and four weeks per neighborhood to be completed; work on a single block will generally take three to four days.
The second phase will occur later in the summer and consists of rotomilling to remove some of the top layer of asphalt, which generally takes two to four hours or less per block to complete and will be performed by the County’s asphalt overlay contractor. The final phase follows rotomilling by one to two weeks and includes placing the new overlay; this last phase may take 4 – 8 hours per block to complete.
