Sandy Creek Covered Bridge boasts the picture-perfect appearance of an old red barn. It was one of six bridges built in 1872 to allow passage from the Jefferson County seat of Hillsboro to St. Louis. John H. Morse built Sandy Creek Covered Bridge using the Howe-truss design, named for William Howe. Howe patented his design in 1840, which featured the use of vertical rods to draw wooden members tight against the top and bottom of the bridge. Three of the four remaining covered bridges in Missouri were built using the Howe-truss design, including Sandy Creek, Burfordville and Locust Creek covered bridges.
