Kentucky Route 155 is a state highway in Kentucky connecting parts of Elizabethtown environs and western Louisville through suburban corridors and commercial districts. The route links arterial roads, interstate connections, and local thoroughfares serving commuters, freight, and regional travelers. It functions as a spine through portions of Hardin County and Jefferson County and intersects major highways that include interstate and U.S. routes.
From its western terminus near Elizabethtown in Hardin County, the corridor proceeds toward Radcliff and crosses local connectors that provide access to Fort Knox. The alignment intersects with state routes and U.S. numbered highways that link to Interstate 65, Interstate 71, and Interstate 64 corridors facilitating travel to Louisville International Airport and Bowling Green. Entering Jefferson County, the highway continues through suburban neighborhoods adjacent to Jefferson Memorial Forest and commercial centers such as Mall St. Matthews and retail strips near Frankfort Avenue. Approaching central Louisville, the route provides connections to U.S. Route 60 and feeder streets that serve destinations including Churchill Downs, University of Louisville, Kentucky Exposition Center, and cultural institutions like the Speed Art Museum. The corridor’s cross-sections vary from two-lane segments to multi-lane arterials with medians and signalized intersections near industrial parks and distribution centers linked to UPS Worldport and regional logistics operations.
The roadway originated as a series of 19th-century plank and turnpike alignments linking Louisville with inland market towns such as Elizabethtown and military installations including Fort Knox during the postbellum era. Early improvements corresponded with statewide campaigns led by the Kentucky Transportation Cabinet and New Deal–era public works initiatives contemporaneous with projects like the Works Progress Administration. Mid-20th century modernization paralleled expansion of the Interstate Highway System and commercial growth patterns driven by suburbanization after World War II; these changes produced bypasses, widening, and grade separations similar to projects near Interstate 265 and Iroquois Park. Late 20th-century developments included reconstruction tied to regional economic shifts influenced by institutions such as the University of Kentucky Medical Center and corporate relocations like Humana and UPS distribution adjustments. Preservation efforts and corridor studies referenced planners associated with entities such as the Louisville Metro Government and regional planning commissions addressing traffic safety and multimodal access in contexts akin to federal programs administered by the Federal Highway Administration.
The highway intersects multiple principal routes that connect to national and regional networks. Key junctions include crossings with U.S. Route 31W, U.S. Route 60, access ramps to Interstate 64, interchanges serving Interstate 65, and connections to Interstate 71 corridors. Other significant intersections link to Kentucky Route 61, Kentucky Route 61 Business, and state-maintained feeders that provide direct access to destinations such as Louisville International Airport and the Kentucky Fair and Exposition Center. The route’s intersections also provide continuity with county roads serving communities including Shepherdsville, Prospect, and commercial nodes near St. Matthews and Jeffersontown.
Several state and U.S. routes operate parallel or intersecting corridors that complement the highway’s function. These include Kentucky Route 61, Kentucky Route 245, Kentucky Route 841, U.S. Route 31E, and local connectors such as Bardstown Road and Third Street Road. The network interrelates with ring-road and connector projects like Interstate 265 and business routes serving Louisville Business First commercial districts, as well as scenic byways that traverse areas near Jefferson Memorial Forest and riverfront corridors tied to the Ohio River and Big Four Bridge precincts.
Planned and proposed improvements reflect regional priorities for congestion mitigation, safety, and multimodal access coordinated by agencies including the Kentucky Transportation Cabinet and Louisville Metro Government. Projects under study or programmed have included intersection upgrades, capacity widening in growth corridors, pedestrian and bicycle facility additions consistent with guidance from the Federal Highway Administration and modal plans of the Kentucky Bicycle and Bikeway Commission, and stormwater and drainage enhancements aligned with standards promoted by the U.S. Environmental Protection Agency for urban watersheds. Economic development incentives attracting employers like Amazon and logistics investments similar to UPS operations inform corridor-level funding discussions that may involve federal grant programs administered jointly with the United States Department of Transportation. Community engagement processes have included stakeholders such as neighborhood associations near St. Matthews, chambers of commerce including the Greater Louisville Inc., and transit planners from agencies resembling Transit Authority of River City in integrated planning for future right-of-way improvements.
