Lebanon Junction is a home rule-class city[4] in Bullitt County, Kentucky, in the United States.

[5] Lebanon Junction is located in southern Bullitt County, on the southeastern edge of Fort Knox.

Interstate 65 passes through the city, with access to the downtown area from Exit 105.

This branch was completed no later than March 8, 1858, and the town grew out of a need for railroad workers to man the terminal and switching station.

This did not hamper the town's growth, however, and by the end of 1912 the business section was rebuilt, offering better facilities than before.

Many a night, townsfolk would pack the gymnasium rebuilt in 1938 after the flood of 1937 to watch basketball games.

Growth leveled off in the 1930s with the onset of the Great Depression and the centralization of railroad operations at the southern Louisville yards.

This, coupled with the drastic decline in commuter train use, the development of diesel engines, and automated switching and traffic control, lowered the importance of the railroad to the town and vice versa.

Recent development in the town includes the aforementioned levee work, the construction of new wastewater processing lagoons, the shutdown of a dollar store, and various restaurants.

A new public library, completed in the summer of 2010, recalls the railroad heritage of the town.

27.4% of all households were made up of individuals, and 14.8% had someone living alone who was 65 years of age or older.
