[citation needed] The original extent of the highway was to be 65.70 miles (105.73 km) with that mileage to have been included with an unconstructed limited-access London bypass and what is east of this area.

Per the Kentucky Transportation Cabinet (KYTC), the Hal Rogers Parkway begins in Somerset, Pulaski County, at the intersection of US 27 and KY 80 north of downtown area.

Passing the eastern terminus of KY 914, the median becomes grass and eventually exits the city limits of Somerset for a more rural area of Pulaski County.

After entering the city of London, the Parkway passes many intersections for minor state highways before interchanging with Interstate 75 (I-75) at its exit 41 around many traveler-related businesses.

East of KY 30/KY 354 and the North Laurel High School, the parkway narrows to two lanes and features a few more at-grade intersections near downtown London.

U.S. Representative Hal Rogers was the forerunner in getting the tolls lifted on the Daniel Boone Parkway, securing $13 million in federal funding.
