Fulton is the second county seat of Calaway county, the original was Elizabeth, six miles south. The county seat was located in Fulton in 1825, making an important stop in the early years of the road. An interesting point of Fulton is that while it was the county seat, Fulton was not incorporated until 1859.
Fulton was originally named Volney, after a French Author. It was renamed in honor of the Steamboat Robert Fulton.
The road originated as an old Indian trace. In the 1764, the first part of the road was expanded by trappers through St. Louis County, Missouri. This part of the road is known as St. Charles Rock Road. The road was expanded by brothers Daniel Morgan and Nathanal Boone, sons of famous frontiersman Daniel Boone, as part of gaining access to salt springs near present day New Franklin, Missouri. The complete road from St. Louis to Franklin, Missouri takes its name from the Boone brothers. In 1821, William Becknell established a road from Franklin to Santa Fe, Mexico, there by establishing the Santa Fe Trail. The Santa Fe Trail at Kansas City splits off into other major wagon roads such as the California and Oregon Trails. The Boone's Lick road is the land route to the beginning of the Santa Fe Trail and carried many of those who would settle the west.
These markers were placed in 1913 by the Daughter's of the American Revolution. The original road was reported to have markers placed along it every few miles. When the DAR placed these markers, they located them where the original markers were placed along the road.
Following the road can give some perspective of how Missouri looked in the 19th century. Asside from modern roads and buildings, once you get outside of the cities, there is a feel for the original topography of the land. The Boone's Lick Road's path can be followed and seen as roads built prior to the I-70's construction. Throughout St. Charles county, the road generally follows MO-94 and County Highway N. As the road progresses through the west, you will see many roads named Boone's Lick Road taking the name from the original road paved over.
From this point you the traveler can travel to the west by visiting Millersburg or back towards St. Louis to the east by visiting Johns Tan Yard.
Perhaps the best website I have seen giving an understanding of the road, is from the
LDS church. Their focus is Mormon usage of the road, but you start to get a feel for the layout of the trail.
