I-15 Mobility Alliance

The I-15 Mobility Alliance includes a select group of public and private sector stakeholders collaborating on the vision for I-15 through the states of Arizona, California, Nevada, and Utah. Organized in 2009, the I-15 Mobility Alliance developed the first I-15 Corridor System Master Plan in 2012, updated in 2017, to provide policy and decision makers with a strategic action plan that defines future transportation infrastructure, and supports national, regional, and local approaches to improve freight delivery, and relieve congestion for years to come. Individuals within the four states and beyond invest their time and resources to keep this economic artery of the west flowing.

The goals of the Alliance include:

  • Reduce or eliminate congestion impacting the interregional movement of people or goods
  • Improve interregional travel time reliability of people or goods movement
  • Improve the safety of the interregional movement of people or goods
  • Construct projects in a manner that respects and honors the unique goals/objectives/standards of each sponsoring community/entity
I-15 Mobility Alliance Structure

Led by senior leadership of the Arizona, California, Nevada, and Utah departments of transportation, the Alliance is committed to working together to fulfill the mission of the I-15 Corridor over the decades of implementation that will be needed to make the Alliance vision a reality.

The Alliance partners come from state and local transportation agencies, local and interstate commerce, port authorities, departments of aviation, freight and passenger rail authorities, freight transportation services, providers of public transportation services, environmental and natural resource agencies, and others. The I-15 Mobility Alliance partners provide invaluable data, resources, and assistance in capturing, analyzing, and summarizing data needed to update and maintain the Corridor System Master Plan as a functional and living document.

The public is encouraged to share ideas with Alliance partnership organizations they belong to—such as local MPOs, chambers of commerce, or other associations—as well as via the Contact website page.

Mission Statement

The I-15 Mobility Alliance transcends traditional transportation thinking by advancing innovation, long-range planning, investment, and implementation of multimodal systems, including not only increased mobility of people and goods through highways, freight rail, transit, and high-speed passenger rail, but also forward-looking technologies for the transport of energy, data, and communications.

The I-15 Corridor is a vital linkage in the economy not only of the western U.S., but of the entire nation. Projected increases in commodity flows from the western U.S. and Mexican ports, and population growth will result in the impacted segments of I-15 experiencing severe congestion thus impeding commerce, hindering mobility, and degrading the quality of life of the people served by the corridor.

The mission of the Alliance and its members is to develop, in partnership with public and private sectors, a comprehensive, multimodal master plan for the I-15 Corridor; prioritize projects and policies of interregional significance; seek financial and other resources necessary for the implementation of the master plan; and devise appropriate governance mechanisms for the ongoing efficient and effective construction, operations, and maintenance of the corridor on a more sustainable basis.
