Thompson Mill Covered Bridge

Thompson Mill Covered Bridge is a covered bridge which crosses the Kaskaskia River 2 miles (3.2 km) northeast of Cowden, Illinois. The 160-foot-4-inch (48.87 m) Howe truss bridge is only 10 feet 7 inches (3.23 m) wide, making it the narrowest covered bridge in Illinois. The bridge was constructed in 1868; it was built in Michigan, shipped to Shelbyville, and hauled to the river crossing by horse-drawn wagons. The road the bridge carried was an important transportation corridor connecting Springfield, Taylorville, and Effingham. The bridge also provided area residents access to the Thompson Mill, a corn mill and sawmill which operated from 1843 to 1914.
