The Sarto Old Iron Bridge, which spans Bayou de Glaises, is a steel truss swing bridge that was completed in 1916 for vehicular and boat traffic. This type of bridge pivots on a central pin to swing open when needed, allowing boats that cannot fit underneath to pass by. Several railroad companies also used the Sarto Bridge on their way east to the Red River, which had no bridge at the time. A community called Naples developed at the point where trains were loaded onto barges and boats pushed steamers through Old River, the Atchafalaya and the Mississippi. The town became a significant railroad terminal, but it was washed away in the Mississippi River Flood of 1927.
