Loop 101 (Price Freeway)
forms the southernmost leg of Loop 101, connecting with
the Red Mountain and Superstition Freeways before terminating
at the Santan Freeway in Chandler. Improvements identified
in the Maricopa Association of Governments (MAG) Regional
Transportation Plan will add HOV lanes in the median
of Loop 101 from the Red Mountain Freeway to the Santan
Freeway. This will be accomplished in two segments.
First, ADOT will complete the segment one design of
the Loop 101 HOV lanes from the Red Mountain Freeway
to Baseline Road in 2007; construction is scheduled
to begin in early 2008. The estimated duration of construction
is 10 months.
The second project segment will add HOV lanes on Loop
101 between Baseline Road and the Santan Freeway. This
project was originally programmed to begin construction
in 2010 but has been accelerated due to the allocation
of Statewide Transportation Acceleration Needs (STAN)
funds by the State Legislature. This segment will be
under design starting in June 2007 with construction
estimated to begin in Spring/Summer 2008. The project
is estimated to be completed in early 2009.
These projects will
enclose the median of Loop 101 by adding the additional
pavement for the HOV lanes and a concrete barrier to
separate the two directions of travel on the freeway.
The new concrete lanes will be paved with rubberized
asphalt once they are complete.
The addition of HOV
lanes on Loop 101 will allow Valley Metro to offer bus
rapid transit service, which is part of the transit
improvements identified in the Regional Transportation
Plan. Buses, vehicles with two or more occupants
and motorcycles are allowed to use HOV lanes during
the Monday through Friday peak commute hours. The HOV
lanes on Loop 101 will be open to all drivers at all
other times.
Projects also are under
development to add HOV lanes on Loop
101 (Pima Freeway) between the Red Mountain Freeway
and State Route 51 to provide new transit and carpool
options for commuters.
The MAG Regional Transportation Plan also has set aside
funding in the final phase of the plan (2021-2025) to
add a fourth lane in each direction on Loop 101 between
Baseline Road and the Santan Freeway.
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 the 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 for Loop 101
(Price Freeway) are on the Current
Studies page.

tax under the voter-approved Proposition
400. (file size: 3.6MB) The Baseline to Loop 202 (Santan Freeway) segment
has been accelerated using STAN funding.
