Other Projects

In addition to the general-purpose lane widening project, ADOT has other upcoming projects in the area of Loop 101 (Pima Freeway).

Black Mountain Boulevard

Black Mountain Boulevard (BMB) CMAR project is located in Maricopa County, within the city of Phoenix, at the traffic interchanges of State Route 51 and Loop 101. The proposed Phase II work consists of constructing two new roadway ramps connecting SR 51 to Black Mountain Boulevard and a pedestrian bridge and roundabout, south of Pinnacle High School.

Project Schedule

Phase II of construction began early June and is expected to be completed in spring 2016.

Phase I was completed in February 2015 and added a new segment of Black Mountain Boulevard (BMB) between Pinnacle Peak Road and Rough Rider Road and also made roadway improvements at Pinnacle High School.
