What to Expect

• Starting March 17, 2024, Monarch Boulevard will be closed to through traffic to allow for the efficient completion of this project. This closure will ensure the safety of both our workers and the traveling public, and we have established clear detour routes to minimize inconvenience.
• The project will be done in four phases. Phase One and Phase Two are scheduled to be completed by September 13, 2024.
• Starting September 13, 2024, Monarch Boulevard will be closed to through traffic from Glen Oaks Avenue north to Briar Dale Drive to allow for the efficient completion of Phase Three, anticipated to be completed in early November 2024. This closure will ensure the safety of both our workers and the traveling public, and we have established clear detour routes to minimize inconvenience.
• The installation of a new water line during the road construction will allow an upgrade to the Castle Pines North Metropolitan District water infrastructure. It will also decrease costs by completing both projects simultaneously. It will reduce the overall project duration and traffic impacts compared to two separate projects.
• Homes within the road closure area will remain accessible. This access will be exclusively for local traffic and emergency services only.

Current Traffic Closures Detours 

• Beginning September 13, Monarch Boulevard will be open to local traffic from Stonedale Drive/Briar Cliff Drive to Glen Oaks Avenue. This will mark the completion of Phase Two of the Monarch Boulevard reconstruction project.
• Homes within the road closure area will remain accessible during construction with two-way travel maintained at the intersection of Burggarten Drive and Briar Dale Drive. This access will be for local traffic and emergency services only.
• Phase Three Detour Information
  • Through traffic on Monarch Boulevard will continue to use the Buffalo Trail detour.
  • Neighborhoods with access from Briar Dale Drive/Burggarten Drive: During the closure, access will be available via two-way traffic north of the intersection of Briar Dale Drive and Burggarten Drive.
