Loop 303 is an important component of the Regional Transportation Plan � a blueprint for Valleywide transportation improvements through 2025.  Plans call for Loop 303 to traverse more than 40 miles of the West Valley � ultimately extending from the proposed State Route 801 (the future I-10 reliever freeway) a few miles south of Interstate 10 in Goodyear to the Interstate 17 (Black Canyon Freeway) near Lone Mountain Road, 2 miles south of the State Route 74 (Carefree Highway).  More . . .

Project Timeline
Project Timeline
The timeline represents the required steps in the development of a roadway or roadway improvement. In addition to establishing a funding source, there is a series of required planning and environmental studies before a roadway is constructed.  More . . .

Improvements
ADOT continually plans for enhancements to the roadway once it is built and in use for maximum efficiency and safety. Various studies identify these enhancements and may influence additional planning, design and construction. Studies for Loop 303 include corridor projects north of I-10 and south of I-10.
