# Kentucky Route 146

Kentucky Route 146 (KY 146) is a 33.505-mile-long (53.921 km) state highway in Kentucky that runs from U.S. Route 60 in the St. Matthews suburb of Louisville to U.S. Route 421, Kentucky Route 55, and Kentucky Route 573 in New Castle via Lyndon, Anchorage, Pewee Valley, Crestwood, Buckner, La Grange, and Pendleton. The route generally follows the Cincinnati-Louisville CSX Transportation rail line, crossing the line once in Lyndon, twice in Anchorage, once at its intersection with Kentucky Route 22 in Crestwood, and once approximately 0.7 miles (1.1 km) east of the Henry/Oldham county line between La Grange and Pendleton. There are no low clearances along the entirety of the mostly two-lane route. The route is rather smartly designed as it carries traffic from Henry County to the east end of Louisville, KY. Interstate 71 exit 28 routes to KY 146 in Buckner. Its speed limit is 55 mph (89 km/h) in the rural parts and 35 mph (56 km/h) in the city limits.
The route is known as New La Grange Road to the west of its first rail crossing in Lyndon and as La Grange Road to the east (outside of city limits). Within the Anchorage city limits, the route is known as Ridge Road east of its westernmost rail crossing in Anchorage, and runs coterminously with Park Road to the west of that crossing. A portion of the route in Oldham County is referred to as the Oldham County Parkway. The route runs coterminously with Kentucky Route 393 for a 0.22-mile-long (0.35 km) stretch in Buckner; it is known as Jefferson Street for approximately 1.5 miles (2.4 km) within the city limits of La Grange, and as West Cross Main within the city limits of New Castle until its eastern terminus.

## Controversy and improvements

Improvement of the route in Henry County has been a contentious topic since the early 2000s; lobbying efforts had been underway for years when the Kentucky Transportation Cabinet funded a $13.86 million improvement plan in 2016 to address the outsized frequency of car accidents on the route, which one local official claimed to be almost three times as common on the road than on other main routes in Henry County. In 2022, a contract was awarded to realign, widen, and improve one of the most dangerous stretches of the roadway. Construction began in 2023 and was scheduled to be completed by the fall of 2024.
