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.

Traffic Interchange.
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.
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.
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.
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.
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.
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.
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 page.
