Corridor Description

The M-10 Corridor includes the Gulf of Mexico, the Gulf Intracoastal Waterway, and connecting commercial navigation channels, ports, and harbors. It stretches from Brownsville, TX to Jacksonville and Port Manatee, FL and includes Texas, Louisiana, Mississippi, Alabama, and Florida. It connects to the M-49 Corridor at Morgan City, LA, the M-65 Corridor in Mobile, AL, and the M-55 in New Orleans, LA.


The I-10 corridor (including secondary roads between Houston and Brownsville and I-75 on Florida’s West Coast and extending to the Tampa/Port Manatee area) parallels the U.S. Gulf Coast, accommodating considerable east-west freight. The U.S. Department of Transportation has identified major freight truck bottlenecks at several points along this corridor, including in and around Houston, New Orleans, and Tampa. Freight rail congestion is also a challenge in and around the Houston area. The National I-10 Freight Study shows 400 miles of the corridor already operating at an unacceptable level of service. Corridor traffic is expected to grow significantly by 2025.

Fortunately, the extensive network of coastal, intracoastal and inland waterways along this corridor can offer relief to the existing and projected travel delays. Although there are already numerous maritime operations along this corridor, a very low percentage carry containerized or roll-on/roll-off freight. However, these existing limited services demonstrate that marine highway operations in this corridor are possible. In addition, large volumes of hazardous materials move along this corridor, which, if transported by water, could improve safety and security.
