Interstate 71 (I-71): Louisville to Cleveland Route, Miles and Crash Record

How long is I-71?

Wikipedia and Interstate Guide both list I-71 at 345.57 miles. The FHWA Route Log, as of January 2026, books 324.46 miles to it, about 21 fewer, and almost all of the difference sits in Northern Kentucky.

I-71 and I-75 run on the same pavement for 19.70 miles, from near Walton to the Brent Spence Bridge at Covington. The Route Log counts that stretch in I-75's Kentucky row, which leaves I-71's Kentucky row at 77.72 miles. Put the shared miles back and Kentucky comes to 97.42, the figure both published sources give. This page uses 97.42 miles when it works out the Kentucky crash rate.

Ohio goes the other way. I-71 shares 1.74 miles with I-70 in downtown Columbus and 0.22 miles with I-75 in Cincinnati, and because I-71's Ohio row of 246.74 miles is longer than either of those routes' Ohio rows, it is the row that already holds the shared pavement. Nothing gets added. Wikipedia gives 248.15 Ohio miles and Interstate Guide 248.02, both within about a mile and a half of the Route Log.

Where I-71 starts and ends

The southern end is the Kennedy Interchange, nicknamed Spaghetti Junction, east of downtown Louisville, where I-71 meets I-64 and I-65. The northern end is on Cleveland's Innerbelt, at I-90 and I-490.

Out of Louisville the road roughly tracks the Ohio River toward Northern Kentucky, picks up I-75 near Walton and passes Florence and Erlanger before crossing into Cincinnati. In Ohio it runs up to Columbus, then Mansfield, and reaches Cleveland through the southwest suburbs of Strongsville and Brook Park.

Interstate junctions along I-71

The main Interstates on I-71 are listed from Louisville north. I-75 shows up once, at the point near Walton where the two merge; they part again in Cincinnati, where I-71 turns east onto Fort Washington Way. Ohio has most of the list: I-70 in downtown Columbus, I-76 in Westfield Township near Seville, I-80 at Strongsville, where it is the Ohio Turnpike, and I-90 at the end of the line in Cleveland.

Fatal crashes on I-71

FARS records 165 deaths in 147 fatal crashes on I-71 from 2020 through 2024, an average of 33 a year. Over 344.16 miles, which is the Route Log total plus the Kentucky miles shared with I-75, that works out to 9.6 deaths per 100 route miles a year, against 9.5 for the Interstate network as a whole. I-71 ranks 23rd of the 56 routes with a rate, close to the middle.

The yearly count peaked at 43 in 2021 and dropped every year after, to 36, then 27, then 26 in 2024.

Ohio had 133 of the deaths and a rate of 10.8. Kentucky had 32 and a rate of 6.6. Franklin County, around Columbus, leads the county list with 30, ahead of Hamilton County in Cincinnati with 17 and Cuyahoga County in Cleveland with 14. Morrow County, between Columbus and Mansfield, had 12, one more than Jefferson County, Kentucky, which includes Louisville.

Bridges on I-71

In the 2025 National Bridge Inventory, the I-71 main line has 323 bridges, 263 in Ohio and 60 in Kentucky. Four are rated Poor, about 1 percent, split two and two between the states. Because Kentucky has so few bridges on the route, its two make up about 3 percent of its total. Of the 323, 200 rate Good, and half were built in 1966 or earlier.

Northbound I-71 uses the lower deck of the Brent Spence Bridge into Cincinnati and southbound traffic the upper deck. When the bridge opened in November 1963, each deck had three 12-foot lanes and 5-foot shoulders. A 1985 restriping changed each deck to four 11-foot lanes with 1-foot shoulders, and the bridge was later rated functionally obsolete. The Brent Spence Bridge Corridor project, which adds a companion span, broke ground on May 8, 2026. The companion bridge is expected by 2031 and the full corridor by 2033.

The twin Jeremiah Morrow bridges carry I-71 239 feet above the Little Miami River, the highest bridges in Ohio.

Tolls on I-71

No part of I-71 charges a toll. Nothing on I-71 appears in FHWA's toll facility inventory dated January 1, 2023, and neither Wikipedia nor Interstate Guide mentions express or toll lanes opened since. I-71 itself is free, but it connects to two tolled roads: the I-65 Ohio River bridges at the Kennedy Interchange in Louisville, tolled through RiverLink, and the Ohio Turnpike, which carries I-80 across I-71 at Strongsville. In February 2022, the governors of Ohio and Kentucky said the new Brent Spence bridge would not need tolls either, and leaders repeated at the May 2026 start of construction that it will be built without tolls.

I-71 auxiliary routes

Two three-digit routes carry the I-71 number. I-471 leaves downtown Cincinnati, crosses the Ohio River to Newport, Kentucky, and ends at I-275, a 5.90-mile trip in the Route Log. I-271 is the longer one at 40.50 miles: it splits from I-71 near Medina and swings through Cleveland's eastern suburbs to I-90.

From turnpike plan to freeway

Much of I-71 in Ohio started out as State Route 1, planned as a second Ohio Turnpike. After the Federal-Aid Highway Act of 1956, the state built it as an Interstate freeway instead. Sections opened from 1959, the SR 1 signs came down in 1966, and the freeway was finished across Ohio by 1975.

Kentucky built its share between November 1965 and July 1969. The Louisville section opened in December 1966, and when the last Kentucky miles opened, I-71 took over from US 42 as the main road between Louisville and Cincinnati.

Cincinnati's Fort Washington Way, the stretch I-71 takes east after leaving I-75, opened in July 1961. Rebuilding began on July 2, 1998, and the last of the new road opened in August 2000, at a cost of $313 million. Farther north, a 25-mile widening through Delaware and Morrow counties wrapped up in mid-2015 for $144 million. In Columbus, the new southbound I-71 flyover above westbound I-70 opened on December 20, 2025.

On May 14, 1988, a wrong-way drunk driver on I-71 in Carroll County, Kentucky, near Carrollton, struck a church bus, killing 27 people.
