Overview

The Arizona Department of Transportation, in partnership with the Maricopa Association of Governments, and in cooperation with the cities of Phoenix, Tolleson, Avondale, Goodyear and Glendale, will be constructing improvements to the Loop 101/Interstate 10 system interchange. This project is included in the Regional Transportation Plan for Maricopa County and is funded through Prop 400, a countywide dedicated half-cent sales tax for transportation improvements approved by voters in 2004.

The purpose of the project is to:

  • Mitigate weaving movements for HOV traffic
  • Improve safety and traffic operations
  • Improve movement at traffic interchanges and surface streets
  • Accommodate future widening projects

Project Area

  • Widening of Loop 101 and I-10 to accommodate the new DHOV ramp
  • A new connection from the south to east freeway system ramp and 91st Avenue, called a ‘slip ramp.’
  • An extension of the southbound Loop 101 off-ramp at McDowell Road
