Thompson Mill Covered Bridge is a covered bridge which crosses the Kaskaskia River northeast of Cowden, Illinois. The Howe truss bridge is only 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. Read more on Wikipedia
