Growth means more strain on our transportation system, slowing down our commutes and our everyday lives. Intentional transportation investment means we can spend our time on the things that matter most.
Voters passed Proposition 300 in 1985 and Proposition 400 in 2004, which have played a large part in shaping the region. Combined, the Propositions delivered Loops 101, 202, and 303, light rail, arterial street investments, and contributions to a growing multimodal network— a total investment of over $12 billion.
A primary focus of the Maricopa Association of Governments (MAG) is developing the next Regional Transportation Plan, MOMENTUM, and planning for the extension of the dedicated sales tax to expand, improve, and optimize our region’s transportation infrastructure.
With a population expected to exceed 6.2 million by 2050, continued investment in well-planned multimodal transportation is critical. Proposition 400, the region’s current sales tax initiative, is set to expire in 2025.
Before Proposition 400 expires, voters will be asked to support the extension of a dedicated sales tax to continue expanding and modernizing our transportation system: the MOMENTUM Investment Plan.
Maricopa County’s early transportation system consisted of Interstate 17, portions of US-60, and local roads. Today, Maricopa County has more than 450 miles of freeway and 28 miles of light rail. To meet the needs of a growing region, we used your input to help us as we developed a new regional transportation plan: MOMENTUM.
Over the last 30 years, the Valley’s freeway network contributed to over $100 billion in time savings.
Investments in transportation across Maricopa County have enhanced property values. On average, property values increased 150% between 2000 and 2019.
A robust economy is supported by a well-planned transportation system to move freight across the region. Well-connected streets and freeways minimize delays and enable business operations.
