Interstate 65, Major interstate highway through Indiana, Kentucky, Tennessee, and Alabama, United States.
Interstate 65 is a long-distance highway spanning 887 miles (1,428 kilometers) and linking four states, from Indianapolis in the north to Mobile in the south. The route crosses different landscapes, including flat farmland, wooded hills, and urban centers.
Construction began in 1958 as part of a nationwide project to create an interconnected highway system for defense and commerce. Completion of the full route stretched over several decades, with southern sections opening only in the 1980s.
The route passes through areas where architecture shifts from Midwestern influences to Southern building styles, showing the change in regional identities. Travelers notice this transition especially at highway rest stops, where local cuisine and dialects change.
The roadway is well maintained in both directions, with multiple lanes and regularly placed service areas for breaks. Traffic volume varies widely, with sections near major cities often busier than rural stretches.
The section through downtown Nashville runs underground in a tunnel that relieves the city center from surface traffic. This tunneled stretch is one of the few places where the highway passes through the core of a major city without using the street surface.
