ADOT opens new SR 51 ramps at Black Mountain Boulevard

The Arizona Department of Transportation has opened elevated ramps that connect State Route 51 at the Loop 101 Pima Freeway with Black Mountain Boulevard. The new ramps provide drivers new options in the Desert Ridge area.

A pedestrian bridge was added over Black Mountain Boulevard near Pinnacle High School, and a roundabout was installed to slow traffic to and from the freeway.

The pedestrian bridge is part of the Reach 11 trail within a 1,500-acre recreation area that’s quite popular with local hikers and for outdoor activities.

Costing ADOT and the city of Phoenix $17.8 million, the project began in June 2015. A separate project done by ADOT included improvements to Black Mountain Boulevard north to Pinnacle Peak Road.

“Our goal has been to deliver a project that helps the city with its transportation plans for the Desert Ridge area and beyond,” ADOT Assistant Director Steve Boschen said. “The ramps provide local drivers with direct access to State Route 51.”

Drivers are notified of the reduced speed as they approach the roundabout with signs indicating drivers to slow to 20 miles per hour.

“As the city continues to develop in the north, better transportation options are needed to meet the needs of a growing city,” Phoenix Councilwoman Thelda Williams said. “The new ramps will provide options for a rapidly growing area.”

Building and expanding the road system in the Desert Ridge area has been part of the city of Phoenix’s plan for several years. This project was funded as part of the Maricopa Association of Governments’ Regional Transportation Plan, which was approved in 2004.
