The bridge is referred to in signage as Pony Express Bridges because there are separate bridges for east and west bound traffic. The bridges were built in 1983 to replace a truss bridge built in 1929. The truss bridge was demolished in March 1984.
The bridge is near the Pony Express stables at its eastern terminus in St. Joseph. US 36 to Marysville, Kansas is designated the Pony Express Memorial Highway because it follows the route. The bridge also passes over the family property of Johnny Fry, the "official" first west-bound rider of the Pony Express.
