Corridor Profiles


The MAFC Nationally Significant Corridor Network identifies and characterizes the most significant freight corridors across the region. Corridors are classified as Tier 1 and Tier 2 corridors, national connectors, and emerging corridors. Certain corridors have multiple classifications due to the nature of freight movements, and as such will be listed multiple times below.

For more information about how the Regional Freight Study classifies corridors, consult the corridor classification methodology.
