Construction Info & Detours

Construction Info:

To expedite construction, scheduled to begin Tuesday, May 26, the Lone Mountain and Vistancia Boulevard intersection will be closed to traffic. Detour signage will be in place to direct travelers around the closure.

Crews will work seven days a week, with work beginning as early as 5 a.m. weekdays, and 7 a.m. on weekends, during this closure.

Construction is expected to be complete by the end of July, with the roundabout fully operational and interim street lighting in place. Scheduled for Sept.-Oct., final installation of street lighting will take place with lane closures to accommodate that work. Thank you for your patience during this work.​​​​​

Alternate (Detour) Routes:

We recognize the closure of the Lone Mountain and Vistancia intersection can be an inconvenience.

For most residents, El Mirage and Westland roads are good alternate routes to or from your destination during the closure. The following neighborhoods have unique access:

  • Residents of Cassia (north of Lone Mountain, west side of Vistancia) will be permitted to travel north on Vistancia with a stop sign in place.

  • Residents of Entrada (southwest corner of Lone Mountain & Vistancia) may use Vistancia to head south or will be permitted to travel west on Lone Mountain with a stop sign in place.

  • Residents of Alicante (southeast corner of Lone Mountain & Vistancia) will be permitted to travel south on Vistancia with a stop sign in place.​​​​​​​​
