Project Overview Closures & Restrictions

As a part of the Regional Transportation Plan (RTP), the Arizona Department of Transportation (ADOT) is constructing one new High Occupancy Vehicle (HOV) lane in each direction on State Route 51 (Piestewa Freeway) between Shea Blvd. up and on to the Loop 101 to Tatum Blvd.  Additionally, as a part of this construction project, ADOT will add new HOV ramp connections to the SR 51 and Loop 101 Interchange identified in the RTP.

Throughout project construction, traffic restrictions and closures will be communicated to stakeholders through regular email notifications, flyer distribution, and media releases to ensure that construction updates and project milestones are appropriately and effectively communicated. Check the Meetings & Notices page for more information.

Public Safety during construction is a priority.  ADOT and its contractors have initiated a unique conveyor system to supply concrete during construction of the HOV lane project.  View the video.
