We are excited to share important updates regarding the Monarch Boulevard reconstruction project. The project is progressing ahead of schedule and under budget. To minimize disruptions next year, additional work, originally set to start in Spring 2025, will now begin September 13, 2024.
What to expect:
- Phase 2 (Stonedale Drive/Briar Cliff Drive to Glen Oaks Avenue) will be completed by Friday, September 13. At that time, local traffic will be able to access Monarch Boulevard from Castle Pines Parkway to Glen Oaks Avenue.
- Phase 3 of the Monarch Boulevard reconstruction will then begin on Friday, September 13. To allow for the efficient completion of this phase, Monarch Boulevard will be closed to through traffic from Glen Oaks Avenue to Briar Dale Drive/Burggarten Drive.
- Phase 3 is anticipated to be complete by early November 2024.
- Communities located along Briar Dale Drive and Burggarten Drive will remain accessible during construction. Two-way travel in and out of these neighborhoods will be maintained. Access will be for local traffic and emergency services only.
- Phase 4 (Briar Dale Drive/Burggarten Drive to Berganot Trail) will begin in early November and be completed by early December.
- Completing additional work for Phases 3 and 4 this year will significantly reduce Monarch Boulevard's construction time in 2025. In 2025, construction will include work from Berganot Trail to Winter Berry Place.
Why are we completing additional work now?
- Completing work now will reduce traffic closures and impacts in 2025. With crews and detour routes already in place, we can quickly mobilize and efficiently complete additional work, greatly reducing closure times for Monarch Boulevard in 2025.
- We have locked in 2024 construction and material prices. Completing work with today's prices and material costs will save tax dollars.
Phase 3 detour information:
- Through traffic on Monarch Boulevard will continue to use the Buffalo Trail detour.
- Communities located along Briar Dale Drive and Burggarten Drive will remain accessible during construction. Two-way travel in and out of these neighborhoods will be maintained. Access will be for local traffic and emergency services only.
Project highlights:
- Complete roadway tear out and asphalt replacement
- Safety enhancements
- Stormwater infrastructure improvements
- Six-foot bike lanes
- Installation of new water line
We recognize the impact of construction on your daily routines and are committed to completing this project as swiftly as possible. For detailed information, including detour routes and project updates, please visit our project webpage.
