 By 1986, it stretched from US 68 (Harrodsburg Road) to Armstrong Mill Road, a distance of a little over 10 miles (16 km).The entire facility was four-lanes divided by a raised grass median, except for the segment from Palumbo Drive to the terminus at Armstrong Mill Road, where it was two-lanes with turning lanes on four-lane right-of-way; that portion of Man o' War was widened in 1987 for $3.3 million.The 2.4 mile (4 km) section from Armstrong Mill Road to Interstate 75 would be one of the costliest segments of the highway to be constructed, as it would feature an interchange at the interstate that was projected to cost $8.2 million.
