I-65 enters the state {{convert|5|mi|km|spell=in}} south of [[Franklin, Kentucky|Franklin]]. Throughout its length, it passes near [[Mammoth Cave National Park]], [[Bernheim Arboretum and Research Forest]], the [[National Corvette Museum]], and [[Fort Knox]].

The first major intersection in the state is with [[Interstate 165 (Kentucky)|I-165]] (former Natcher Parkway) at [[Bowling Green, Kentucky|Bowling Green]]. I-65 has intersections with three of the [[List of Parkways and named roads in Kentucky|parkways]] in the state. The first major junction is with the [[Cumberland Parkway]] near Rocky Hill. At [[Elizabethtown, Kentucky|Elizabethtown]], it has two more parkway interchanges with the [[Wendell H. Ford Western Kentucky Parkway]] and the [[Martha Layne Collins Bluegrass Parkway]]. I-65 also has interchanges with [[Interstate 265|I-265]], [[Interstate 264 (Kentucky)|I-264]], [[Interstate 64|I-64]], and [[Interstate 71|I-71]].

The widest stretch of I-65 in its entirety is in Louisville at [[Kentucky Route 1065]] (KY&nbsp;1065, Outer Loop), where the main line is 14 lanes wide. The highway crosses the [[Ohio River]] into Indiana on a toll bridge. The southbound side is called the [[John F. Kennedy Memorial Bridge]] (southbound) and the northbound side is called the [[Abraham Lincoln Bridge]]. The latter bridge opened in October&nbsp;2016 as part of the [[Ohio River Bridges Project]]. Prior to the project, the John F. Kennedy Memorial Bridge (completed in 1963) carried traffic in both directions. The project also included reconstruction of the [[Kennedy Interchange|I-65/I-64/I-71 convergence interchange]] just south of the Kennedy Bridge, as well as renovating the older span to carry six lanes of southbound traffic. Additionally, a second six-lane cable-stayed bridge {{convert|12|mi|km}} upstream on the Ohio River, the [[Lewis and Clark Bridge (Ohio River)|Lewis and Clark Bridge]], was built as part of the project, opening in December&nbsp;2016 to complete the I-265 loop around Louisville.

At one time, the {{Convert|65|mi|km|adj=on}} stretch of I-65 from Louisville to Elizabethtown was a toll road, called the [[Interstate 65 in Kentucky#Kentucky Turnpike|Kentucky Turnpike]]. The bonds that financed the road have been paid off, and tolls are no longer collected. All signs of the former turnpike have been removed.

On November&nbsp;15, 2006, the stretch of I-65 from Bowling Green to Louisville was renamed the [[Abraham Lincoln]] Memorial Expressway.

On February&nbsp;12, 2007, a bill passed the [[Kentucky Senate]] to rename I-65 in [[Jefferson County, Kentucky|Jefferson County]] the [[Dr. Martin Luther King Jr.]] Expressway.<ref>{{cite news |work= The Courier-Journal |location= Louisville, KY |date=February 13, 2007 |last=Gerth |first=Joseph |title=Senate OKs renaming I-65 for King}}</ref> Signs were posted July&nbsp;25, 2007.<ref>{{cite news |work= The Courier-Journal |location= Louisville, KY |date= July 25, 2007 |last= Shafer |first= Sheldon S. |title= Mayor, Democrats back I-65 King plan |url= http://www.courier-journal.com/article/20070125/NEWS01/701250404/Mayor-Democrats-back-I-65-King-plan |access-date=July 30, 2007}}</ref>

On July&nbsp;15, 2007, Kentucky highway officials raised the speed limits on most Interstate and state parkway highways to {{convert|70|mph|km/h|abbr=on}}. Prior to that, Kentucky was the only state along I-65 that had a maximum speed limit of {{convert|65|mph|km/h|abbr=on}}.
