Landside Corridor Served
The M-5 Corridor includes the Pacific Ocean coastal waters, connecting commercial navigation channels, ports, and harbors from San Diego, CA to the US-Canada border north of Seattle, WA. It spans Washington, Oregon and California along the West Coast. It connects to the M-84 Corridor at Astoria, OR,
and the M-580 Connector at Oakland, CA.
This corridor contains several areas identified by the U.S. Department of Transportation as having
considerable annual truck hours of delay, most notably in the urban areas of California, Portland, OR,
and Seattle, WA. The Department reports that Southern California and the Pacific Northwest are also plagued with freight rail congestion. Total domestic trade movements between the three States along the I-5 Corridor are expected to grow from 145 million tons per year to 366 million tons by 2030,
exacerbating existing challenges. Navigable coastal waters that parallel the entire I-5 Corridor, combined with numerous deep and safe rivers, bays, and ports, can help to accommodate some of this expected increase in traffic, reducing landside travel delays and greenhouse gas emissions
along this essential freight corridor.
M-580: The Sacramento Valley
Port of Stockton, California
Bay Area Air Quality Management District, San Joaquin Valley Air Pollution Control District, Port of Oakland, and the Port of West Sacramento. Landside Corridor Served: Interstate-580 Corridor Description: The M-580 Corridor includes the San Joaquin River, Sacramento River, and connecting commercial navigation channels, ports, and harbors in Central California from Sacramento, CA to Oakland. It connects to the M-5 Corridor at Oakland.
Landside Corridor Served
The M-580 Corridor includes the San Joaquin River, Sacramento River, and connecting commercial navigation channels, ports, and harbors in Central California from Sacramento, CA to Oakland. It connects to the M-5 Corridor at Oakland.
I-580 is one of the most congested highways in the nation, and has been identified by the U.S. Department of Transportation as having significant annual truck hours of delay. Approximately 25 percent of the Port of Oakland’s volume travels to and from the San Joaquin Valley of California, an area already recognized for some of the country’s worst air pollution. By 2020, the Port of Oakland’s volume is expected to increase by 65 percent, further exacerbating the Valley’s congestion and air quality issues. An increased movement of freight by water could help to relieve this situation. In 2007, nearly 3.4 million tons of waterborne cargo, mainly bulk goods, moved through the Port of Stockton via the Stockton Deepwater Ship Channel and San Joaquin River, underscoring the potential capacity of this waterway system. One example of the potential for waterborne freight movements along this corridor is a proposed marine highway service between the Ports of Oakland, Stockton, and West Sacramento. Fully implemented, it could eliminate 180,000 truck trips from I-580, I-80, and I-205 annually, saving approximately 7 million gallons of fuel and reducing air emissions in the process.
M-84: The Columbia Valley
Port of Portland, Oregon
Pacific Northwest Waterways Ass.
Landside Corridor Served
The M-84 Corridor includes the Columbia and Snake Rivers, connecting commercial navigation channels, ports, and harbors. It spans Oregon and Idaho from Astoria, OR to Lewiston, ID. It connects to the M-5 Corridor in Astoria, OR.
I-84, which parallels the Columbia River in Oregon, has been identified as a freight truck bottleneck by the U.S. Department of Transportation, resulting in up to 750,000 truck hours of delay annually. This is also noted by the Department as an area of major rail congestion. Containers from the Ports of Seattle, Tacoma, and Portland currently move by truck on I-84 (and I-5), and 55 percent of the region’s container market moves through Puget Sound, causing additional truck and rail freight traffic between these ports.
Increasing the use of the water route paralleling I-84 can help mitigate landside congestion, reduce air emissions, and conserve energy. A container-on-barge service currently calling on smaller ports along the Columbia and Snake Rivers is one example of the corridor’s potential. A proposed weekly service between the Ports of Umatilla, Portland, Seattle, and Tacoma could also accommodate the equivalent of 36,000 trucks that travel the I-5 landside corridor each year. An operation like this could serve both agricultural exporters and importers in the Pacific Northwest shipping to Far East markets.
