I65

Interstate 65 (I-65) is a major north–south highway in the central United States and part of the Interstate Highway System. It runs from its southern terminus at I-10 in Mobile, Alabama, north to the Chicago metropolitan area in Gary, Indiana, near the border with Illinois. The route serves as a primary corridor for regional commerce, tourism, and long-distance travel.

I-65 traverses four states: Alabama, Tennessee, Kentucky, and Indiana. Along its length, it connects Gulf Coast markets with the Midwest and provides access to several large urban centers and regional hubs. The highway passes through or near multiple metropolitan areas and serves as a key link between the southern plains and the Great Lakes region.

The corridor plays an important role in freight movement and passenger travel, linking ports and inland markets with manufacturing centers and agricultural regions. It intersects with various other interstates and U.S. routes, forming part of a broader network that supports cross-country mobility and economic activity.

History and construction of I-65 were implemented as part of the National Interstate System established in the mid-20th century. Construction occurred in phases over several decades, with different segments opening from the late 1950s through the 1970s and, in some sections, into the early 1980s. The highway is maintained by the state departments of transportation in each state it traverses: Alabama, Tennessee, Kentucky, and Indiana.

I-65 remains one of the principal north–south routes in the central United States, facilitating regional transit, interstate commerce, and regional development.
