The study evaluates current and future conditions, reviews past recommendations, and gathers input from stakeholders and the public to shape proposed solutions.

State Route 74 Corridor Transportation Study

The goals of the State Route 74 Corridor Transportation Study are to provide a coordinated vision of the State Route 74 corridor across jurisdictions. This includes recommendations that enhance the mobility and accessibility of people and goods within the corridor in reflection of existing and future development plans, as well as identification of the necessary infrastructure improvements at the Interstate 17 interchange, US 60 interchange, and Lake Pleasant Parkway intersection.

Meridian Road - Superstition Boulevard to State Route 24

The Maricopa Association of Governments is conducting a corridor study of Meridian Road between Superstition Boulevard and SR 24, in partnership with the cities of Apache Junction and Mesa, and the counties of Maricopa and Pinal. The study will develop a vision for future improvements to address existing and future travel needs for residents and businesses, improve connectivity, and enhance safety for drivers, bicyclists, and pedestrians.

Pima Road Corridor Study

The purpose of the Pima Road Corridor Study is to better understand travel characteristics and potential roadway improvements to improve capacity along Pima Road between Las Piedras and Cave Creek Road. The study will help the City of Scottsdale and the Town of Carefree gain a better understanding of transportation needs along the study corridor and provide a strategic implementation plan for this section of Pima Road to support projected growth. The Study will establish recommendations for the roadway type, number of travel lanes, right-of-way (R/W) needs, recommended intersection geometry and control, and general alignment required to accommodate both pedestrian and bicycle facilities based on current and future traffic volumes. This study will establish near and long-term solutions for each of these project features.

Cave Creek Road Widening Study

The study will assess existing and future travel demands within the study corridor and develop a program of recommended roadway and intersection improvements. These improvements would help accommodate future travel demands, improve safety, enhance regional connectivity, and support the planned development in the area.

US 60 (Grand Avenue): SR 303L to SR 74 Corridor Study

The purpose of the study is to conduct a comprehensive assessment of both current and future travel demands within the study area and identify a series of transportation investments that will accommodate the future traffic demand along the US 60 corridor. As part of the study, transportation infrastructure improvements will be identified, not only to address existing travel needs, but also to support anticipated development in the surrounding area through 2050. Through rigorous modeling, community outreach, and identification of key arterial street corridors, the study aims to develop a realistic future network for the study area.

Interstate 10 Freeway Corridor Study – Deck Park Tunnel to I-10/I-17 Split

The purpose of the study is to recommend design elements, operational strategies, and policy actions that may serve as the basis for design and construction for future projects in this corridor. Ver esta página en español.

State Route 30 (Tres Rios Freeway)

This project included a scoping study and completion of the FHWA Planning and Environmental Linkages (PEL) process for the section of State Route 30 between SR 202L and I-17 at the Durango Curve. The study identified a 1,000-foot corridor alignment that met the project’s purpose and need while minimizing impacts to businesses, residents, and land owners.

Laveen South Mountain Transportation Study

This project's goal is to identify transportation infrastructure for improving traffic in the Laveen area. This will help ease stress placed on the system from continuing development through community feedback and a data-driven analysis.

SR 347 Scoping Study

MAG is conducting a scoping study with member agencies to allow for timely improvement of the corridor. The primary work product will be a recommended plan to provide a safe and reliable SR 347 corridor that supports forecasted growth.

I-8 & I-10/Hidden Valley Roadway Framework Study

The purpose of the Hidden Valley Framework Study is to establish a conceptual network of freeways, parkways and arterials that will be capable of meeting long-range traffic demand, and applied at many different jurisdictional levels.

Central Phoenix Framework Study

This study will balance future needs against the current challenges of providing multimodal transportation. This study will also take into account shrinking revenues and growing environmental and energy concerns.

I-10/Hassayampa Valley Roadway Study

Much of the reason for this one-year study came from the need to preserve and improve Interstate 10, which currently the only freeway serving the area. It is the primary corridor for moving people and goods between Phoenix and the ports in Los Angeles and Long Beach.

Southeast Corridor Major Investment Study

In response to growing demand between the East Valley and Central Phoenix, MAG developed the Southeast Corridor Major Investment Study (SE Corridor MIS). Its purpose is investigating alternate transportation strategies. This includes identifying member agency needs and developing a multi-modal approach in accordance with anticipated traffic volume on Interstate 10 between the SR 202L/Santan-South Mountain “Pecos Stack” and the SR 51/SR 202L/Red Mountain “Mini-Stack” interchanges. This study also included the US-60/ Superstition Freeway and the Interstate 17/Black Canyon Freeway traffic interchanges.

I-10/I-17 "Spine" Corridor Master Plan

In partnership with the Federal Highway Administration (FHWA) and the Arizona Department of Transportation (ADOT), MAG launched this study to develop a Corridor Master Plan for the Interstate 10 and Interstate 17 corridor. This corridor is referred to as the “Spine,” because it serves as the backbone for transportation in the metropolitan Phoenix area. The highway handles over 40 percent of all daily freeway traffic in the region.

US-60/Grand Avenue COMPASS Study

US-60/Grand Avenue is an important regional facility controlled and maintained by the Arizona Department of Transportation (ADOT) as part of the National Highway System (NHS). Because of its significance to local agencies, it has been the subject of many studies, improvement projects, and public interest. It serves multiple purposes, including local access, commuter travel, and freight movement. It also serves as a link to Kingman and Las Vegas.
