Loop 202 (South Mountain Freeway)


Welcome to the South Mountain Freeway information site!

The Loop 202 (South Mountain Freeway) adds 22 miles of freeway to the existing Phoenix metropolitan transportation system. The freeway connects the east and west valley while providing much needed relief to existing freeway corridors and local streets.

Here you will find everything you need to know about the project – whether you are interested in project history, the new shared-use pathmedia, or simply receiving construction updates to stay in the loop.
