Connectivity of the I-73/74/75 Corridor
One of the most significant benefits of completing the I-73/74/75 Corridor is its power to connect people, places, and opportunities. By linking rural areas with major cities, industrial centers, and tourism destinations, the corridor expands access across six states—improving the flow of goods, services, and travelers throughout the region.
Connectivity: Bridging Communities
The I-73/74/75 Corridor strengthens the national transportation network by uniting key interstates, ports, and railways. This integrated system boosts efficiency, enhances trade routes, and supports economic growth through improved regional mobility.
INTERSTATES
The corridor connects with major highways including: I-696, I-475, I-95, I-94, I-85, I-81, I-80, I-79, I-77, I-71, I-70, I-69, and I-40. These links improve both north–south and east–west mobility.
PORTS
- Northern Terminus (Sault Ste. Marie, MI): Soo Locks move 10,000+ ships annually between Lake Superior and the lower Great Lakes.
- Southern Terminus (Myrtle Beach, SC): Within 75 miles of Charleston (SC), Georgetown (SC), and Wilmington (NC) ports.
- Additional access to ports in NC, VA, WV, OH, and MI.
RAILWAYS
The corridor intersects major rail lines (Norfolk Southern, CSX, Canadian National) in 36 locations, creating a multimodal network.
