We are pleased to announce theĀ opening of limited lanes in the roundabout at Happy Canyon Road and Lagae Road beginning Monday, June 3. Access to and from the roundabout will be open from Lagae Road to the north and Happy Canyon Road to the south. The west travel lane from I-25 will also be open.

During this phase of the project, the portion of the roundabout heading east to Happy Canyon Bridge/I-25 will be closed as the team completes a few final project steps, including updates to the deer guard. Click on the detour map to the right to view more information about the closure. This closure is expected to last approximately one week and is essential to safely and efficiently complete the final construction stages. To access I-25 from Happy Canyon Road, an alternate route will be available by traveling north on Lagae Road to Castle Pines Parkway.

The entire roundabout is expected to open in the next few weeks, ahead of schedule. We appreciate your patience and cooperation as we enhance the city's infrastructure.
