Fort Knox, US 60 connects with US 31W, and they remain together until downtown Louisville. Originally built as a bypass route around downtown Louisville, US 60 Alt. used several existing roads running through Louisville to get between the east and south sides of town without having to travel through the heavily congested downtown or west ends of town. US 60 Alt. runs northeast to southwest from St. Matthews to Shively; including a stretch on one of Frederick Law Olmsted's last remaining parkways, Eastern Parkway. Before its completion and designation as I-264 in 1984, the Henry Watterson Expressway connecting Dixie Highway (US 31W/US 60) and Shelbyville Road (US 60) was signed US 60 Bypass. After passing Shelbyville, it continues through the state capital of Frankfort, becomes four lanes and then heads more south than east toward Versailles. In Versailles, US 60's eastbound lanes are very briefly the westbound lanes of US 62, which runs more south than west at that point. After turning east and intersecting the Bluegrass Parkway, US 60 is one of the major routes through Lexington. Shortly after entering Fayette County, the road becomes a 6 lane heavily traveled highway, known as Versailles Road. It passed Bluegrass Airport and Keeneland before intersecting with Lexington's beltway, New Circle Road. It is now a 4 lane road going into downtown Lexington. After downtown, it once again becomes a 6 lane road now known as Winchester Road. It passes several suburbs of Lexington before entering northern Hamburg and then intersects I-75 and from there roughly parallels I-64 and goes to Winchester and passes very near the Mountain Parkway but does not intersect with it. It proceeds to Mount Sterling, Morehead, past Carter Caves State Resort Park, on to Grayson and finally to Ashland. US 23 southbound follows US 60 eastbound into Catlettsburg, where they split at 35th Street. US 23 southbound continues straight as a four-lane highway, while US 60 eastbound turns onto 35th Street, passes Oakland Avenue, and enters Kenova, West Virginia via the Billy C. Clark Bridge. History When the first finalized proposal for the U.S. Highway System was presented by the Bureau of Public Roads in December 1925, the route between Ozark, Missouri and what would become U.S. Route 52 (US 52) in West Virginia near Ashland, Kentucky was originally proposed as US 62. The US 60 designation was proposed along a different highway from Los Angeles, California
