About the Bill

What's being proposed?

In November 2022, voters in Arizona will cast their votes for candidates for United States Senator, Governor, Arizona State Legislature, as well as vote on several statewide and local ballot measures.

One of the issues that may be on the ballot is the continuation of Maricopa County’s existing half-cent sales tax for transportation that was previously passed by voters in 2004.  

Here is the proposal:
“A measure continuing the current transportation sales tax for an additional 25 years to address the regional transportation system by building new freeways, expanding existing freeways with additional access and capacity, constructing streets and intersections, expanding transit by extending the light rail system, increasing the frequency of bus service, and providing additional bus, dial-a-ride, and vanpool services.” 52% of Arizona voters believe Maricopa County is on the right track. 

What do Arizona voters think?

Maricopa County voters have voted to support this investment twice over the past 40 years. This funding has permitted us to build over 300 miles of new freeways, hundreds of miles of street investments, and funded our first-ever county-wide transit system.
