leading into Downtown Cincinnati. The hill is known for its high number of automobile accidents. In 2006, the Cut-in-the-Hill averaged over seven times more accidents when compared to similar roadways in Kentucky. At the Cut-in-the-Hill, the northbound road takes a sharp left turn into a steep grade down to the Ohio River—about in . Accidents are usually attributed to a combination of speeding, curvy lanes, poor weather, longer stopping times for trucks traveling downhill, and traffic congestion. The area earned the sobriquet "Death Hill" shortly after I-75 opened in 1962. By 1968, a total of 23 people died in crashes on the hill, so a concrete wall was installed to separate northbound and southbound traffic. The wall helped reduce fatal crashes, but accidents continued, and, in 1977, the hill averaged 583 automobile accidents per year. In 1986, a tractor-trailer lost control, leading to an accident that caused a

banned most northbound tractor-trailer traffic from the hill. From 1989 until 1994, $50 million (equivalent to $ in ) in reconstruction was spent to straighten the hill's S-curve and add a fourth lane for southbound traffic, and, in 1995, the truck ban was lifted. Also as part of the reconstruction, ramps were added at Pike Street to give complete access, while an interchange with Jefferson and Euclid avenues was obliterated. In 2006, the hill and the Brent Spence Bridge saw 151 crashes in the northbound direction and 121 crashes in the southbound direction, totaling 272 in all. To help reduce the number of accidents, a flashing "Steep Grade" sign was installed and a Kentucky State Police trooper was assigned to patrol just the Cut-in-the-Hill. Additionally, eight

Kentucky officials are reportedly working to raise more than $2 billion to replace the section of highway, but, , no construction is planned.
