Highlights of a completed project

What began as the “Southwest Loop Highway” in 1983 turned into the Loop 202 (South Mountain Freeway), which was completed in 2020. The Arizona Department of Transportation, together with the Federal Highway Administration, its agency partners and local and regional stakeholders, worked through the environmental process for nearly 30 years. After four years of construction, the freeway provides the much needed route to connect the east and west sides of Greater Phoenix.
