Interstate 71 (I-71) is an Interstate Highway in the Great Lakes/Midwestern and Southeastern region of the United States. Its southern terminus is at an interchange with Interstate 64 and Interstate 65 (the Kennedy Interchange) in Louisville, Kentucky. Its northern terminus is at an interchange with Interstate 90 in Cleveland, Ohio. I-71 runs concurrently with Interstate 75 from a point about twenty miles (30 km) south of Cincinnati, Ohio into downtown Cincinnati. Almost three quarters of the route lies east of I-75, thereby putting it out of its proper place in the Interstate grid.
While I-71 is designated a north-south highway, it is a major east-west route for cross-country traffic. It links I-80 and I-90 to I-70, and ultimately (via I-65) links to I-40.

Route description
Kentucky
In Kentucky, I-71 begins east of Downtown Louisville at the Kennedy Interchange, where it meets I-64 and I-65. This interchange is sometimes called the "Spaghetti Junction". From Louisville, it roughly follows the Ohio River in a diagonal path toward Northern Kentucky. Between Louisville and Cincinnati, I-71 is largely a four-lane highway, except for a couple of miles in Sparta in which it runs three lanes each way.
Near the town of Carrollton, there are signs marking the location of a tragic accident that occurred on May 14, 1988, when a drunk driver crossed the median and struck a church bus full of children and teenagers, causing the bus' fuel tank to ignite into flames and killing 27 people on board. It is one of the worst bus accidents in state and national history.
I-71 merges with Interstate 75 near Walton and intersects Interstate 275, the Cincinnati beltway. After passing through Covington, the freeway crosses the Ohio River via the lower level of the Brent Spence Bridge (while the southbound direction uses the upper level) and continues into Cincinnati.
Ohio
In Cincinnati, I-71 splits immediately from I-75 and heads due east onto Fort Washington Way, where it continues through downtown Cincinnati concurrently with US-50 for less than a mile. Just east of downtown, US-50 splits from I-71 and continues east; I-71 bends north and receives Interstate 471, a spur from southeast of the city. I-71 then heads in a general northeast direction through urban Cincinnati and into its surrounding suburbs. After another interchange with the Interstate 275 beltway, the freeway leaves the metropolitan area and heads towards Columbus. It continues northeast until it reaches South Lebanon, Ohio, where it begins cutting east across the flat plains of southwest Ohio. The freeway crosses the Little Miami River on the Jeremiah Morrow Bridge, which is a continuous truss bridge and the tallest bridge in Ohio at 239 feet above the river. I-71 heads towards Columbus then intersects with the bypass I-270 before heading north into urban Columbus, where it junctions I-70. About a mile north of the I-70 junction, it intersects with I-670. After another interchange with the I-270 bypass, the highway exits out of Columbus and continues north until near Delaware, where it again turns northeast. Beginning its path to Cleveland, I-71 enters the rolling farm country on the edges of the Allegheny Plateau. It continues in this fashion to Lodi/Westfield Center and its junction with I-76, which provides access to Akron. Heading north to Medina, it meets the terminus of I-271. The highway then continues north into urban Cuyahoga County and Cleveland's suburbs, intersecting the Ohio Turnpike/I-80. Passing Cleveland Hopkins International Airport, I-71 meets I-480 and enters Cleveland's west side, continuing on to downtown. It junctions with State Route 176 and terminates at Interstate 90 on the Innerbelt.

History
Kentucky
The first section of I-71 in Louisville opened in December 1966 between its terminus at Spaghetti Junction and Zorn Avenue, its first exit. Its junction with I-264 opened in July 1968, and the complete Kentucky portion of the interstate was opened to the public in July 1969. At that point, it replaced U.S. Route 42 as the primary link between Cincinnati and Louisville.
Ohio
Much of Interstate 71 in Ohio was intended to be State Route 1. State Route 1 was originally planned in the 1950s as a second Ohio Turnpike extending southwest to northeast across the state. It was planned to run from Cincinnati to Conneaut and connect with an extension built across the panhandle of Pennsylvania to the New York State Thruway. As the highway was being planned, the Federal Aid Highway Act of 1956 was enacted, and the project was converted from a toll road to a freeway. It was designated as State Route 1, since the Interstate Highway numbering system had not yet been implemented. Portions of the freeway began to be completed and opened in 1959 with the new Interstate Highway funding, and they were marked as State Route 1 as well as with their new Interstate Highway number. Since large gaps existed along the corridor where no freeway had yet been completed, existing two-lane or four-lane highways were also designated as State Route 1 in order to complete the route. The State Route 1 signage was removed in 1966 as the Interstate Highway numbers adequately marked the route by then and the state highway numbering was superfluous.
In Columbus, the portion of Interstate 71 that bounds Worthington's eastern edge was originally called the North Freeway. Costing US$13.8 million, it was constructed south from Route 161, arriving at 11th Avenue by August 1961. It took another year to construct the portion between 11th Avenue and 5th Avenue, mainly due to the need to construct a massive underpass under the Pennsylvania Railroad's Grogan Yard. Today, only two tracks cross the viaduct, and the rest of the structure supports a large, weedy field. By August 1962, the freeway had reached Fifth Avenue, and it reached downtown in November 1962.
Interstate 71 was originally planned to follow the Innerbelt Freeway northward from its current northern terminus to the Cleveland Memorial Shoreway at Dead Man's Curve when Interstate 90 was planned to continue westward from there along the Shoreway.
Upon its completion, I-71 replaced State Route 3 as the primary highway link between Cincinnati, Columbus, and Cleveland.
Between 2004 and 2006, the interchange at milepost 121 in the far northern reaches of Columbus was reconstructed to allow access to the eastern extension of Gemini Place. Before that, it was a simple diamond interchange with Polaris Parkway (Ohio State Route 750).
Rebuilding and widening program
In 1999, the state of Ohio began a 10-year, $500 million project to improve I-71 between Columbus and Cleveland. The plans did not include widening the 25-mile stretch in Delaware and Morrow counties, calling for patching that section instead. At that time, state transportation officials said they didn't plan to widen that section for two reasons: Traffic studies didn't support the widening, and there was no money for the project. But ODOT officials eventually gave in under pressure from elected officials and business owners to widen the remaining 25-mile stretch of I-71 from just north of the U.S. 36/Ohio 37 interchange in Delaware County to the Morrow/Richland county line. The reconstruction and widening on the last 25-mile stretch of I-71 in Delaware and Morrow counties began in spring 2012 and the work was completed in summer 2015 at a cost of $144 million.
