Significance: The Mountain Fork Bridge is an excellent Arkansas example of a pony Pratt steel truss bridge. This bridge design was very common in the state in the late nineteenth and early twentieth century and readily available to county judges from a variety of bridge companies. Its design reflects the bridge engineering period before the Arkansas Highway and Transportation Department (AHTD) standardized a majority of the most common bridge designs used in the state beginning in the 1920s.
