The Poinsett Bridge is the oldest bridge in South Carolina and perhaps in the entire southeastern United States. It was built in 1820 as part of a road from Columbia, South Carolina to Saluda Mountain. The stone bridge, which includes a 14-foot Gothic arch and stretches 130 feet over Little Gap Creek, is believed have been designed by Robert Mills (he designed many public structures in South Carolina during that time period). Mills is also the architect for the Washington Monument
