Along the early turnpikes, law required mile posts made either of stone or cast iron that showed the distance to each end of the road. Typical stone markers include 14 along the east side of the present highway at their approximate original locations beside the old Bardstown and Louisville Turnpike. The Bardstown and Louisville Turnpike Co., chartered by the Kentucky Legislature in 1831, was capitalized at $130,000 and later increased to $200,000, with shares owned half by individuals and half by the state. The turnpike was completed July 1, 1838, at a cost of $203,598; the road was 29 miles long and 60 feet wide cleared, with 40 feet graded. Tolls collected during the year ending October 1841 amounted to $9,755.
