The Central Phoenix Transportation Framework Study (CPHX) was a continuing effort to identify long-range transportation needs for the center of the MAG region in an area bounded by SR-101L on the north, east, west and the Gila River Indian Community on the south.

Beginning in 2010 and completed in 2014, the effort produced a series of technical memorandums on the following subject areas:

  • Improvement Strategies
  • I-10/I-17 “Spine” Corridor
  • Freeway System Plan
  • Direct HOV ramps and Park-n-Rides
  • Direct DHOV Ramps Development Policy Guidance
  • Diverging Diamond Interchanges
  • Active Traffic Management
  • Roadway Maintenance
  • Freeway Interchange Options
  • Arterial Improvement Strategies
  • Transit Improvement Concepts
  • Pedestrian/Bicycle Concepts


Each technical memorandum, along with the study executive summary poster, can be found under “Materials”.
