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.
