Freight Overview

Globalization, evolving trade relationships, and technological advances continue to change economies around the world. Each of these factors has an effect on the transportation network that serves the region and the ability to meet the changing demands for freight.

Approximately 53 million tons of goods, valued at $123 billion, originated and terminated within the four Alliance states along the I-15 corridor transportation network on all transportation modes:

An estimated 86 million tons of goods worth $244 billion are expected to travel along the I-15 corridor annually by 2040.



The I-15 Corridor is an avenue for truck movements out of the ports and agricultural regions of Southern California and onward to major cities such as Las Vegas and Salt Lake City.

Considering the continued growth of port traffic, without improvements, the roadways supporting the ports will be congested and will experience greater delays in the future. Furthermore, safety and congestion issues within metropolitan areas along I-15 will continue to slow traffic and degrade reliability of goods shipment along this corridor.

Freight Rail

Without improvements, demand is expected to exceed both freeway and rail capacity, resulting in costly shipping delays.

The two largest U.S Class 1 railroads, BNSF Railway (BNSF) and Union Pacific (UP), are the only Class 1 railroads that operate in the study area. In 2015, approximately 400,000 tons of goods, valued at $220 million, originated and terminated within the four Alliance states along the I-15 corridor, which constitutes a small fraction of the total goods moved by rail through this corridor destined for points beyond (Freight Analysis Framework, version 4, 2015).

Air Cargo

Most air cargo has a high value and is transferred to trucks for quick delivery to its final destination.

The I-15 corridor moves approximately 52,000 tons by air valued at approximately $5 billion (Freight Analysis Framework, version 4, 2015). Some of the major air cargo airports along the corridor include Los Angeles International (LAX), McCarran International Airport (LAS), and Salt Lake City International (SLC).

Ports of Entry

The reliability of the network to transport goods from the Ports of Entry through inland distribution centers and on to the end consumer underlines the very nature of this Master Plan and the importance of the I-15 Corridor to the region, nation, and world.

The Port of Los Angeles and Port of Long Beach have worldwide significance, and are the busiest ports in the U.S. for container traffic. Otay Mesa is the third largest land port of entry between the US and Mexico. These ports are major economic drivers for California and the region. As a primary collector-feeder route between Southern California, Mexico, and Canada, the U.S. relies on goods moving on the I-15 Corridor, because it provides an efficient connection between primary east-west trade corridors.
