Project Overview Closures & Restrictions
The Loop 202 (Santan Freeway) is open to traffic and was completed in June 2006. The Loop 202 serves drivers from Chandler, Gilbert and southeast Mesa and is currently being landscaped. The opening of the 12 miles of the Santan in June 2006 was the longest single stretch of freeway ever opened in the Valley’s history.

Current Loop 202 Activity

Loop 202 (Red Mountain and Santan Freeways) Gilbert Road to Interstate 10 – A planning process is underway to prepare for the addition of High Occupancy Vehicles lanes on this 39 mile section of Loop 202. Details regarding this project are available on Current Studies page.

Project Timeline
Project Timeline
The timeline represents the required steps in the development of a roadway or roadway improvement. In addition to establishing a funding source, there is a series of required planning and environmental studies before a roadway is constructed.

Voter Approval
In November 2004, Maricopa County voters approved a 20-year extension of a half-cent sales tax until December 31, 2025, 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.

Planning
Freeway planning to determine potential future corridors and freeway improvements is conducted well in advance of design and construction. Area population growth, future land use, jurisdictional responsibilities, and other factors are used to determine the need, feasibility and general location of future freeway improvements.

Study
The study stage establishes the location (alignment) and basic characteristics (number of lanes, type of traffic interchange, etc.) of a roadway. Accompanying this are environmental studies (noise, economic impacts, 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.

Design
The design of a roadway involves several stages of detailed engineering and technical review and interim levels of approval. Project information is shared and discussed with the public at project milestones, and public input is considered in the evaluation of alternatives. The final design of the roadway is represented in plans and specifications that construction contractors use to prepare construction bids.

Construction
Road construction for projects is based on detailed plans and specifications provided to the contractor following the approved design. As the construction process advances, changes may occur that are influenced by a variety of factors. ADOT continually looks for ways to improve the construction process for maximum efficiency and minimal community impact. Once built, a roadway will be maintained and improved over time as a result of future growth and transportation needs.

Improvements
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. Studies for the Loop 202 (Santan Freeway) are on the Current Studies page.
