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. The right-of-way purchase from Palumbo Drive to Interstate 75 began in August 1986; construction was completed two years later. The alignment chosen followed south of KY 1927 east of Armstrong Mill Road, then cross to the north side of Bryant Road and interchange with Interstate 75 approximately 200 feet north of the Bryant Road overpass.
