St. Charles Rock Road
St. Charles Rock Road is the current name of what was the first road to traverse present-day St. Louis County, Missouri, United States, between St. Louis City and St. Charles. For most of its length it is also known as Route 180.
Route description
Its present-day origin is at the border of the cities of Wellston and Pagedale, starting as a co-signed road with pre-existing Route 180 at a T intersection with Lucas-Hunt Road. Route 180, up to this transition point, is co-signed with Dr. Martin Luther King Drive, from Route 180's eastern terminus in St. Louis' Kingsway East neighborhood; Dr. Martin Luther King Drive originates farther east than Route 180, where the Martin Luther King Bridge crosses the Mississippi River into central St. Louis. St. Charles Rock Road/Route 180 proceeds northwest past several cemeteries, crosses under I-170 within St. John, then continues through Breckenridge Hills and St. Ann. As it enters Bridgeton, it crosses over I-70 and then under I-270. From I-270 it continues northwest towards the banks of the Missouri River, ending opposite St. Charles at Missouri Bottom Road.History
In the 1760s, St. Louis and St. Charles were the two major European settlements in the lower Missouri River Valley. A path between the two came to be known as King’s Highway, a name used in colonial times by the Spanish and then the French for many frequently used roads. The southeastern end of the road became known as St. Charles Street.On May 20, 1804, Capt. Meriwether Lewis reached St. Charles, the expedition's last "civilized" stop, via St. Charles Rock Road to meet up with Lt. William Clark. The Lewis and Clark Expedition then officially began with 40 to 50 men – the precise number is unknown.
In 1819, St. Charles Road was established as a post road and stagecoach road; by 1837 it became a turnpike. The road furnished access to the Santa Fe Trail and Oregon Trail for the many westbound wagon trains that were outfitted in St. Louis. After passage of the Missouri Plank Road Law in 1851, it became an oak plank road. In 1865, St. Charles Road was rebuilt with macadam and renamed St. Charles Rock Road. In 1921, it became the first concrete state highway in St. Louis County. In 1953, St. Charles Rock Road was completed as a divided two-lane highway along much of its length.
