Interstate 10 / Loop 101 System Interchange

Interstate 10 / Loop 101 System Interchange


The Arizona Department of Transportation has initiated a study to evaluate improvements to the Loop 101 (Agua Fria Freeway) and Interstate 10 system traffic interchange in the West Valley.

The purpose of this study is to evaluate alternatives to the interchange that will enhance regional travel by improving safety, reducing congestion and improving connectivity.


Project Area

Interstate 10/Loop 101 System Interchange map

Maricopa County is one of the largest and fastest-growing regions in the United States, and the county’s population is expected to increase by nearly 30 percent between 2020 and 2040. Traffic volume projections indicate congestion will worsen in the future due to growth in the region.


Study Elements

  • A new Direct High-Occupancy Vehicle ramp within the existing interchange that will accommodate travel to/from the north along Loop 101 and to/from the east along I-10.
  • A possible new connection between southbound Loop 101 and 91st Avenue. This connection would be separate from the Loop 101/I-10 system interchange ramps and may connect to the existing I-10/91st Avenue interchange ramps.
  • Evaluation of several other traffic interchange locations and connecting arterial roadways for possible improvement within the project area.
