Schedule

• Project start: March 17, 2024
• Anticipated completion: fall 2024

What to Expect

• Starting March 17, 2024, Monarch Boulevard will be closed to through traffic to allow for the efficient completion of this project, anticipated by fall 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 project will be done in two phases. Phase One will begin on March 17, and Phase Two will begin on July 15.
• 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 also reduce the overall project duration and traffic impacts compared to two separate projects.
• A full closure of Monarch Boulevard will be in place to expedite the project and maintain safety for residents and construction crews.
• 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 Monday, July 15, local traffic access will open on Monarch Boulevard from Castle Pines Parkway to the intersection of Stonedale Drive/Briar Cliff Drive. This will mark the completion of Phase One of the Monarch Boulevard reconstruction project. Through traffic will continue to use the Buffalo Trail detour.
• Work will also begin on Phase Two of the project on Monday, July 15. This phase extends from Stondale Drive/Briar Cliff Drive to Glen Oaks Avenue. During Phase Two, Monarch Boulevard will be closed from Stonedale Drive/Briar Cliff Drive to Glen Oaks Avenue. The project remains on schedule and is expected to be completed this fall.
