Located in Algona, this large Quadrangular Through Truss bridge crosses the Canadian Pacific branch line.
Originally built in 1917 to cross the Milwaukee Road, this bridge features a single Quadrangular Through Truss, set onto concrete abutments.
The quadrangular truss was a favorite of the C&NW, particularly due to the durability and versatility of the structure.
Currently, the bridge is owned by Union Pacific, and is still operated. Overall, it remains in good condition, with little major deterioration.
The author has ranked the bridge as moderately significant, due to the truss design.
