Sugar Creek Covered Bridge is a covered bridge which crosses Sugar Creek southeast of Chatham, Illinois. The Burr truss bridge is 110 feet (34 m) long and 30 feet (9.1 m) wide. The bridge was constructed by Thomas Black; sources disagree on the date of construction, placing it at either 1827 or 1880. The State of Illinois acquired the bridge in 1963 and extensively renovated it two years later. The bridge closed to traffic in 1984 and is now part of a local park with a picnic area. It is one of only five historic covered bridges in Illinois and is the oldest of the remaining bridges.
