A brief history of the Minneapolis & St. Louis mainline from Mason City to Peoria and Albia:


Read an article about the Schaub variant truss.

This unique truss bridge crosses the Iowa River just south of Albion in a very scenic location.
Built in 1902, the main span is a 136 foot long, Schaub variant through truss with all verticals and an A-Frame Portal.
It rests on stone piers, which are mainly encased by concrete. On the south end, it is approached by a long trestle.
The Schaub variant truss is a take on the traditional Warren design, developed by Julius Schaub in 1901. While the original design featured a combination of pin and riveted connections, this bridge utilizes purely riveted connections.
The Schaub design offered a savings of material and a reduction of traditional stresses in truss members. Schaub considered it to be an ideal link between long pin connected spans and short riveted spans.

The north abutment is a basically an encased stone pier abutted against a concrete pad.
It is a nearly identical match to the Bridge near Union

The author has ranked the bridge as being moderately significant, due to the unique design.
