Built in 1854, Mary's River Covered Bridge remained in continuous service from 1854 to 1930 and was originally part of a planked toll road between Breman and Chester. All of the bridge's timber is original except for the floor, floor joist, roof, and siding. The State of Illinois acquired it in 1936 for preservation and a picnic area, and money to purchase the site was donated by the Chester Chamber of Commerce.
