Clarkson Bridge, spanning Crooked Creek in Bethel, Cullman County, is one of the longest covered bridges in the state. The 270-foot-long structure was built in 1904 and remains in its original location. Now closed to vehicle traffic, it is the centerpiece of a county park that also features a grist mill and a dogtrot log cabin. The park is located in the vicinity of the April 1863 Battle of Hog Mountain, which took place during the Union cavalry campaign known as Streight's Raid. The bridge was listed on the National Register of Historic Places in 1974.
