The Departments of Transportation (DOT’s) in California, Nevada, Arizona, and Utah have formed a cooperative alliance to develop a long-range multimodal transportation system master plan that will address current and future mobility needs along the I-15 corridor from Southern California to Northern Utah.
More than just a traditional transportation study, the I-15 Corridor System Master Plan (Master Plan) is an alliance of public and private agencies and users of the I-15 corridor working together to enhance the movement of people, freight and other commodities for decades to come. Multimodal solutions being studied to improve mobility within the corridor include moving more people and goods via rail, air, and transit in addition to potential highway and local/regional road network improvements. This Master Plan will also consider solutions and infrastructure improvements for the “transportation” of energy, data, and communications within the corridor.
The mission of the I-15 Mobility Alliance will be to:
- Develop a vision that informs partners and the public of the importance of the corridor for future economic development
- Prioritize projects for all modes of transportation
- Develop funding strategies, including the leveraging of federal funding sources and public-private partnerships, to advance priority projects
- Influence state and federal transportation policy
- Streamline the project delivery process
I-15: Critical Commerce Corridor
Critical to the economic vitality of the Western United States, the I-15 Corridor moves people and goods to and from major trade gateways, tourist destinations and population centers from Mexico in the south to Canada in the north. Its prestigious designation in 2007 as a Corridor of the Future recognizes that the health of the corridor directly impacts the wealth of the region it serves.
I-15 is a victim of its own success as today it plays host to five of the top 100 worst freight bottlenecks in the country (ATRI, 2009). The combination of aging infrastructure, critical safety concerns and chronic congestion costs our economy millions of dollars a year in delays as a result of its inefficiencies. Without immediate attention the deficiencies that slow down the corridor today will bring it to a standstill in the next two decades.
I-15 At a Glance
- 1,434 miles of interstate highway—60% (840 miles) of it within the 4-state I-15 Mobility Alliance
- Traverses the Nation's fastest growing regions
- Moves goods to and from the Ports of Long Beach and Los Angeles—which handle over 40% of the nation's container cargo (SCAG Multi-County Goods Movement Action Plan, 2008)
- Links 4 of the nation's top 20 airports including top international gateways Los Angeles International Airport and McCarran International Airport (FAA 2009 Statistics)
- The average cost of congestion per auto commuter in the I-15 corridor urban areas ranged from $848 in San Diego, CA to $306 in Provo, UT in 2009 (FHWA, FAF3 Network Database)
- Lifeline to $75+ Billion, multistate tourism industry (Utah Tourism Office, Center for Business and Economic Research, CA Tourism Industry Website)
- Designated by USDOT in 2007 as one of 6 Corridors of the Future
