Thompson Mill Covered Bridge

The Thompson Mill Covered Bridge extends 160 feet across the Kaskaskia River, featuring a traditional wooden framework with a protective roof structure and Howe truss design.

The bridge materials, manufactured in Michigan during 1868, reached their destination through horse-drawn wagons from Shelbyville to the current river crossing location.

This wooden bridge stands as one of only five remaining historic covered bridges in Illinois, representing 19th-century American engineering and transportation methods.

Located 2 miles northeast of Cowden, Illinois, the bridge remains accessible for pedestrian use while motor vehicles are no longer permitted on the structure.

At just 10 feet 7 inches in width, this structure holds the distinction of being the narrowest covered bridge throughout the state of Illinois.
