The study team, led by the Arizona Department of Transportation and the Federal Highway Administration, has released the Draft Environmental Impact Statement for the Loop 202 South Mountain Freeway Study. The April 26, 2013 release begins a 90-day public comment period that will conclude on July 24, 2013. A full-day public hearing on the Draft EIS will be held on May 21, 2013.
The proposed South Mountain Freeway has been a critical part of the Maricopa Association of Governments’ Regional Freeway Program since it was first included in funding through Proposition 300 approved by Maricopa County voters in 1985. The freeway was also part of the Regional Transportation Plan funding passed by Maricopa County voters in 2004 through Proposition 400.
The South Mountain Freeway is the last piece to complete the Loop 202 and Loop 101 freeway system necessary for high-quality regional mobility.

Public comments are a vital component in the decision-making process and one of the many criteria used in evaluating alternatives. All public comments received during the 90-day public review period for the Draft EIS will be considered and included in the Final EIS and the project’s administrative record.
The public is encouraged to review the Draft EIS, participate in the public hearing (see information below), and provide comments on the project.

In 1985, Maricopa County voters approved funding for a Regional Freeway System, which included a South Mountain Freeway connecting Interstate 10 south of Phoenix with Interstate 10 in the West Valley. Due in part to a funding shortfall, the Arizona Department of Transportation was unable to develop 76 miles of planned freeways, including the South Mountain segment. The unfunded corridor, however, remained part of the planned Regional Freeway System. More | Close
Funding for the South Mountain Freeway was approved by voters in November 2004 with the passage of Proposition 400, which continued an existing half-cent sales tax through 2025 for improvements identified in the Regional Transportation Plan (RTP).
The Arizona Department of Transportation is charged with implementing the highway component of the Regional Transportation Plan which includes $13.2 million in new freeways, freeway improvements and maintenance.
As a lengthy and detailed transportation study, the information presented on this web site includes both current and archived data. Some of this data may no longer be accurate or applicable to the current status of the proposed freeway study. While we have tried to separate current from archive information, ADOT is sincerely committed to conducting this study openly and fairly, so we have maintained many years worth of documents, presentations and other information as part of this site to help provide a comprehensive reference for all members of the community until the formal environmental documents are released for public review and comment. If you have questions about the current-day accuracy of a document or want to inquire about the latest developments, we are always happy to provide personal assistance.
This section details the required steps in the development of a roadway or roadway improvement. In addition to establishing a funding source, there are a series of required planning and environmental studies before a roadway is constructed. More | Close
In November 2004, Maricopa County voters approved a 20-year extension of a half-cent sales tax until 2026 to fund a comprehensive package of transportation improvements as part of a Regional Transportation Plan. Funding for the plan, which includes $9 billion in regional freeway improvements in Maricopa County, became effective January 1, 2006.
Responding to federal transportation planning requirements, the RTP is being extended through 2031 by the Maricopa Association of Governments (MAG) to maintain a 20-year planning horizon. As a result, a fifth phase has been added to the RTP, covering the period from 2026 through 2031. Consistent with federal planning guidelines, funding for transportation projects is based on revenue sources that are considered to be reasonably available for the planning period. This assumes that for planning purposes funding sources with a long history of providing funding in the past will continue into the future.
In fall 2009, due to declining sales tax revenues and decreases in other transportation revenue sources to fund improvements, MAG recommended that some future projects be deferred to Phase V of the plan. As part of the planning process, project costs and funding levels are continuously monitored, and the RTP is periodically updated to take advantage of cost savings or changes in the transportation revenue outlook. This can result in the acceleration of projects that were formerly deferred. For more information about RTP projects deferred to Phase V in the MAG tentative scenario, please visit the MAG Web site.
The planning stage establishes the general location (alignment) and basic characteristics (number of lanes, type of traffic interchange, etc.) of a roadway. Accompanying this are environmental studies (noise, traffic volume, etc.), identification and evaluation of alternatives, general cost estimates, coordination with public and private partners and the determination of feasibility to move to the design phase.
The design of a roadway involves several phases of detailed engineering and technical review and interim levels of approval. The final design of the roadway is represented in plans and specifications that construction contractors use to prepare construction bids.
Road construction for projects is based on detailed plans and specifications provided to the contractor following the approved design. ADOT continually looks for ways to improve the construction process for maximum efficiency and minimal community impact. Once built, a roadway may be improved over time as a result of future studies.
ADOT continually plans for enhancements to the roadway once it is built and in use for maximum efficiency and safety. Various studies identify these enhancements and may influence additional planning, design and construction.
