The I-10 Broadway Curve Improvement Project is identified in the Maricopa Association of Governments’ Regional Transportation Plan, funded by a half-cent sales tax approved by Maricopa County voters in 2004 through Proposition 400. MAG identified the need for this project to reduce travel times on I-10 during peak hours; improve airport access; support ridesharing and transit; and prepare the region for future growth projections.
