Cumberland Parkway
The Louie B. Nunn Cumberland Parkway is an 88-mile-long (142 km) east–west controlled-access highway in the U.S. state of Kentucky, extending from Barren County in the west to Somerset in the east. It is one of nine highways that are part of Kentucky's parkway system.
The parkway begins at an interchange with Interstate 65 (exit 43) between Smiths Grove and Park City. It travels east through rolling farmland to its eastern terminus at U.S. Route 27 in north of Somerset. The road parallels Kentucky Route 80 for its entire length. The parkway passes the cities of Glasgow, Edmonton, Columbia, and Russell Springs. It passes near two popular state parks: Lake Cumberland State Resort Park and Barren River Lake State Resort Park. The length of the parkway is designated unsigned Kentucky Route 9008 (LN 9008).
The road is named after Louie B. Nunn, a former Kentucky governor from Barren County who was instrumental in the road's creation. Originally called the Cumberland Parkway from its opening in 1972-1973, it was renamed for Nunn in 2000.
Presumably, the Nunn Parkway was built to Interstate Highway standards at its time of construction aside from some at-grade intersections and traffic signals near its east end, which were eliminated in 2010 by constructing a northwestern bypass around Somerset. The east end of the parkway is currently a full cloverleaf at U.S. 27. An extension to complete the northern bypass is in the works.
