Boeckman Bridge was a historic suspension bridge over Big Tavern Creek near St. Elizabeth, Miller County, Missouri, listed on the National Register of Historic Places. It was built in 1926, and was replaced by a concrete bridge in 2002.

Bridge

Boeckman Bridge was a 240-foot, wire cable and timber suspension (swinging) bridge. The deck was 185 feet long and 12 feet wide and was suspended 29 feet above the creek; it consisted of flooring beams nailed to transverse stringer beams that rested on floor beams supported by the cables. All of these and the two portals were untreated locally milled oak. The main cables, anchored in concrete at each end, and the suspender cables were zinc-clad wire; for the main cables, 300 strands of wire were strung across the creek using a suspended bicycle wheel and then bound with an additional strand. A three-foot wire fence safeguarded pedestrians, and originally an additional wire was strung at each side of the floor beams and independently anchored at each end in order to steady the bridge in strong winds.
