US 60 (Grand Avenue), 35th Avenue and Indian School Road Intersection Improvements

The Arizona Department of Transportation (ADOT), in coordination with the city of Phoenix and Maricopa Association of Governments (MAG), prepared a Draft Environmental Assessment (EA) and Design Concept Report (DCR) for the US 60 (Grand Avenue), 35th Avenue and Indian School Road intersection (known as the Grand-35 Study).

Proposed Improvements

  • Raise 35th Avenue to create a new elevated intersection with Indian School Road above Grand Avenue.
  • Shift 35th Avenue to the west.
  • Shift Indian School Road to the north.
  • Construct new bridges for 35th Avenue and Indian School Road over the BNSF railroad and Grand Avenue.
  • Keep Grand Avenue at-grade and remove the existing intersection and traffic signal.
  • Extend Glenrosa Avenue to the west to create a new intersection with Grand Avenue.
  • Remove the existing intersection at 33rd Drive and Indian School Road.
  • Extend 33rd Avenue north of Indian School Road where a new east-west roadway would connect 33rd Drive to 33rd Avenue.
  • Construct a cul-de-sac on 37th Avenue north of Grand Avenue.
  • Add a turn lane at the Grand Avenue/33rd Avenue intersection.
  • Make accommodations on 35th Avenue and Indian School Road for future high-capacity transit.
  • Enhance safety and improve bicycle, pedestrian, and bus facilities such as additional or wider sidewalks, wider outside shoulders for bikes, separate bus pull-outs or new bus shelters.
