Phoenix Metro Area Projects

State Route 24

The Arizona Department of Transportation is currently constructing the first mile of the newest freeway in the Phoenix metro area, SR 24 in Mesa.

The initial phase of SR 24 will be a one-mile stretch beginning at Loop 202 (Santan Freeway) near the Phoenix-Mesa Gateway Airport and ending at Ellsworth Road. Once completed, motorists will look forward to enhanced access from southeast Maricopa County to northeast Pinal County and additional routes in and out of Phoenix-Mesa Gateway Airport and surrounding schools and businesses.

Additional phases of this project, east of Ellsworth Road, are suspended until the North-South Corridor Study in Pinal County advances. No funding is currently identified for the portion in Pinal County.

What to Expect

In addition to the new one-mile stretch of SR 24, the current project requires construction activity to occur on Loop 202 (Santan Freeway), as well as at Ray, Power and Ellsworth roads.

Once completed the new system interchange will include:

  • two flyover structures connecting Loop 202 to SR 24.
  • new lighting along Loop 202 and SR 24.
  • new traffic signals at Hawes and Ellsworth roads.
  • landscape improvements.
