Black Mountain Boulevard Construction Project

​​Black Mountain Boulevard (BMB) is a planned major arterial roadway in the City of Phoenix General Plan extending south approximately five miles from the Sonoran Boulevard/Cave Creek Road intersection to the ramp connections at SR 51 and Loop 101. This roadway will significantly improve access within the Desert View Village area of north Phoenix. Since 1994, the BMB ramp connections to SR 51 were planned as part of the Outer Loop Freeway system. Preliminary Engineering and an Environmental Assessment started in late 2011.

Based on the results of the Study’s Alternatives Evaluation Process, the build Alternative 1A (south of Deer Valley Road) and 1-N (north of Deer Valley Road), along with the no build Alternative 4 (no connection to SR51) were carried forward through detailed analyses in the Environmental Assessment. The Draft Environmental Assessment was presented at a Public Hearing where further public comments were recorded.

The following items were provided as back-up material at the hearing:

After more than a year of planning and coordination with the public, local homeowner’s associations and government agencies, the City of Phoenix and Arizona Department of Transportation received the approved Final Environmental Assessment from the Federal Highway Administration in October 2013. This enabled the regional federal funding to be released for the final design and construction of the portion of Black Mountain Boulevard from Loop 101 to Pinnacle Peak Road.
