Loop 101 (Pima Freeway) begins at Interstate 17 in Phoenix and transitions to the Loop 101 (Price Freeway) at the Loop 202 (Red Mountain Freeway).

Current Loop 101 (Pima Freeway) Activity:

I-17 to Princess Dr. FMS Construction	Construction of Freeway Management System (FMS) for this segment of Loop 101. Using sensors, freeway cameras and the latest technology, the Valley’s Intelligent Transportation Systems keep traffic flowing by providing incident management personnel with information about real-time traffic conditions.
SR 51 to Loop 101 HOV Construction	Construction of High Occupancy Vehicle (HOV) lanes designed to aide in relieving traffic congestion during morning and evening rush hours, encourage carpools and public transportation, allow for express bus service, shorten travel time, and reduce the overall number of vehicles on the road.
Tatum Blvd. to Princess Dr.	Construction of High Occupancy Vehicle (HOV) lanes designed to aide in relieving traffic congestion during morning and evening rush hours, encourage carpools and public transportation, allow for express bus service, shorten travel time, and reduce the overall number of vehicles on the road.
64th St. Traffic Interchange	64th Street is planned to be a six-lane arterial and will be elevated approximately 30 feet above the existing ground over Loop 101. The interchange will provide freeway access ramps (entry/exit) for both directions of Loop 101. Also included in the project are new auxiliary lanes (merging lanes) on Loop 101 to connect the 64th Street traffic interchange with the 56th Street and Scottsdale Road traffic interchange ramps. This will help to improve the merging ability for vehicles entering and exiting the freeway.
Princess Dr. to Loop 202	Construction of High Occupancy Vehicle (HOV) lanes designed to aide in relieving traffic congestion during morning and evening rush hours, encourage carpools and public transportation, allow for express bus service, shorten travel time, and reduce the overall number of vehicles on the road.
Princess Drive to Loop 202 (Red Mountain Freeway) General Purpose Lanes Study	Design Concept Report/Environmental Study to add one general purpose lane in each direction on the Loop 101 (Pima Freeway) between Princess Drive and Loop 202 (Red Mountain Freeway). Study initiated in February 2008 with anticipated completion fall 2009.
