The Valley’s Loop 202 South Mountain Freeway, proposed by regional planners since the 1980s, received final approval from the Federal Highway Administration, paving the way for the Arizona Department of Transportation to move the project forward.
The Record of Decision, signed March 5 by the Federal Highway Administration, grants the final approval necessary for ADOT to begin the process of acquiring right of way, complete the design, and begin construction of the 22-mile-long freeway to serve the metro Phoenix region.
ADOT has determined that, pursuant to an unsolicited proposal submitted to construct the freeway, construction will follow a public-private partnership path, helping to speed construction and reduce overall costs.
The freeway would not be tolled under any public-private partnership proposal, but would include a private group involved with final design, construction and a 30-year agreement to maintain the freeway.
The South Mountain Freeway is the last piece to complete the Loop 202 and Loop 101 freeway system necessary for high-quality regional mobility, according to regional planners.
The Federal Highway Administration has decided to identify the Preferred Alternative (a combination of the W59 and E1 Alternatives) as the Selected Alternative for the South Mountain Freeway project. This decision along with supporting information, including responses to public comments received on the Final Environmental Impact Statement, is documented in the Record of Decision.
The freeway will be constructed with four lanes in each direction – three general-use lanes and one HOV lane – and modern features that have made Arizona freeways stand apart from other states for a generation, including rubberized asphalt and aesthetics designed in partnership with the community.
The $1.9B project is expected to take about four years to construct.
