Transportation

History
Franklin was established as the county seat of Simpson County in the early nineteenth century, with Simpson County itself having been formed in 1819 from parts of Allen, Logan, and Warren counties. Like much of south-central Kentucky, the area's early economy was rooted in tobacco farming, which remained a dominant agricultural force for well over a century. Franklin's location along major north-south travel corridors helped it develop as a regional trade center, and the arrival of the railroad in the nineteenth century further cemented its role as an important community hub in the region.
Did you know?
One lesser-known fact about Franklin is that its position straddling the Kentucky-Tennessee border has made it a crossroads community where the cultures and economies of both states have long intersected, giving it a unique dual character not found in most Kentucky cities. The city's location directly on Interstate 65 also means that hundreds of thousands of travelers pass through or near Franklin each year, quietly making it one of the more strategically positioned small cities in the commonwealth.
