One of the most important jobs of the Maricopa Association of Governments (MAG) is to develop a long-range regional transportation plan (RTP), which guides how our region spends its transportation dollars. As part of the RTP development process, MAG created different transportation scenarios to illustrate a range of reasonable, possible futures. These scenarios were used to help policymakers determine a set of proposed projects and program investments over the next few decades.
MAG’s Scenario Planning Report illustrates key characteristics, benefits, and tradeoffs of different choices for our future, and documents the technical analysis of the scenario planning process.
After the scenarios were developed, MAG asked for feedback from residents about future transportation investments in our region. The results of this outreach are summarized in the Public Input Report.
The results of public outreach combined with the technical analysis in the Scenario Planning Report helped our policymakers weigh different tradeoffs and make difficult decisions about the combination of transportation projects and programs for the next 25+ years. Learn more about the Proposed Investment Plan below.
In June 2021, the MAG Regional Council approved the project listing for the proposed MOMENTUM plan. The projects include a suite of investments including freeway improvements and high capacity transit expansion. These projects can be viewed and explored in the map below.

The proposed future investment strategy is so much more than the high capacity projects mapped above. MAG Regional Council has also directed significant investment into various programs that align with MOMENTUM’s goals. This strategy to focus investment in programs, such as safety and bus transit, will provide greater flexibility and ensure that the region can best respond to critical needs now and into the future—even if we don’t know the solutions or technologies today.
Investments in bicycle lanes, protected paths and other projects to create better connectivity and improve safety for non-motorized transportation users.
More bicycle lanes, separated/protected paths and greater connectivity in the off-street path network, providing a safer environment for all users.
Investments to mitigate impacts of the transportation system and improve the region’s air quality.
Cleaner air to promote better health and improve the environmental quality of the region.
Investments to enhance the region’s “grid” street network to improve safety and mobility.
Improved traffic flow, and reimagining street design to create streets that are safer and function better for all users.
Investments to continue to operate and further grow the region’s bus transit system.
Greater coverage and improved bus service that better matches your needs and schedule.
Investments to enable the region to respond and adapt to future transportation innovations.
A more modern transportation system that is responsive to your needs.
Investments in technology that manage the movement of people and goods through the region.
Technologies like traffic signals, ramp meters and freeway message boards to help you get around more quickly and safely.
Investments in projects and initiatives that improve safety across the system and for its users.
Peace of mind that you or your family will be able to get from A to B with fewer risks.
Investments in strategies that optimize the region’s existing transportation infrastructure and manages its use, especially at “rush hour."
More options for getting around and strategies that help make your trips easier.
