Project Overview
Closures & Restrictions

Interstate 10 (Maricopa Freeway) seamlessly joins I-10 (Papago Freeway) in the central core of the Valley. The I-10 (Maricopa Freeway) then heads east and south, giving access to Tempe, Chandler and other East Valley communities. Currently, there are three projects under way on the I-10 (Maricopa Freeway) including:

I-10 ~ State Route 51/Piestewa to Loop 202/Santan Freeway Corridor Improvement Study

Quiet Pavement #8 ~ Van Buren Street to Baseline Road

I-10 Ray Road Bridge Widening Project

Public and Community Outreach
Public and community outreach for any projects along the I-10 (Maricopa Freeway) corridor will involve several jurisdictions, businesses, residents, recreational facilities, and government agencies. Impacts to this highly utilized stretch of freeway require the implementation of broad and efficient communication efforts.

Therefore, a network of contacts is constantly being established and updated. If you wish to receive updates regarding improvement projects along the I-10 (Maricopa Freeway) corridor please complete the Comment Form and we will add you to future outreach efforts.

Project Timeline
Project Timeline
This 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 the 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.

Project Funding
I-10 (Maricopa Freeway) projects under construction are funded with the half-cent sales tax under the voter-approved Proposition 400.
