Cahokia Mounds

Cahokia Mounds. The Road to America's Oldest City. , In 1806, President Thomas Jefferson signed legislation creating America's first federal highway. The National Road would join the bustling cities of the East to the resource-rich wilderness of the West, connecting state capitals, county seats, and smaller centers of commerce along the way. , The Road pressed west from Cumberland, Md., reaching Illinois in 1828. It crossed creeks and rivers, passed through prairie, forest and marsh, and into a fertile flood plain known as the American Bottom. Here, it led travelers through the remains of America's oldest city, a metropolis that thrived more than 500 years before Jefferson was born. , Road to Ruin , By the end of the 1800s, the National Road had spawned cities across eastern Illinois, opened the state's western counties to settlement, and plotted a path for the St. Louis, Vandalia and Terre Haute Railroad. , Westward migration and urbanization came at great cost to the mounds. Marvels of earthen engineering that had stood for centuries fell to ploughshares, or were cut and carted away as fill to support the growing network of roads and rails. , Road to Recovery , Throughout the 20th century, archaeologists and concerned citizens battled commercial and residential development to preserve and protect what remained of the Cahokia complex. In 1956, conservationists found an unexpected ally in the Federal-Aid Highway Act. The act funded archaeological surveys and artifact recovery at sites compromised by federal highway construction. , By 1960, plans for Interstates 55 and 70 were in place. The resulting salvage archaeology led to the discovery of Woodhenge, a cultural artifact that contributed to Cahokia Mounds being named a UNESCO World Heritage Site in 1982. , [Captions:] , In AD 1150, some 10,000 to 20,000 Mississippians lived at and around Cahokia Mounds, making it larger than many European cities at the time. Seven centuries after Cahokia reached its peak, the mounds were noted in National Road survey notes and travelogues., Schmidt's Mound Park stood on the National Road east of Monks Mound. The site supported an inn, tavern, bandstand and casino. Schmidt's Mound was eventually razed for construction of a retail store., Built in 1929, Cahokia Mounds' first museum was located north of the National Road. , At the turn of the 20th century, wagon wheels, steam locomotives and streetcarrs cut through the Cahokia complex, as illustrated by this map from 1906., This illustration from an 1873 Madison County atlas shows the home of T.T. Ramey atop Monks Mound. The National Road, known locally as Collinsville Road, is in the background., [Sidebar:] , A Road of Dirt, Rock, And Dreams , In 1806, President Thomas Jefferson signed legislation to provide federal funding for a National Road. Surveyed from Cumberland, Md., to the Mississippi River, the National Road was a highway for pioneers eager to settle the West., Today, as US 40, the National Road in Illinois spans 164 miles. From Indiana to East St. Louis, you can still see how the ambitions and accomplishments of early Illinois immigrants shaped our communities. You'll find their influence in our art and architecture, our industry and agriculture, and in our way of life. Enjoy your time on the Road.
