Little Mary's River Covered Bridge was built in 1854. It was in continuous service from 1854 to 1930. Originally it was part of a planked toll road between Breman and Chester. All of the timber in the bridge is the original, with the exceptions of the floor, floor joist, roof and siding. It was acquired by the State of Illinois in 1936 for purposes of preservation and a picnic area. Money for purchase of the site was donated by the Chester Chamber of Commerce.
