The Wabash Railroad Bridge is a historic structure located south of Pella, Iowa, United States. It spans the Des Moines River for 561 feet (171 m). The Des Moines and St. Louis Railroad (D&S) was built through the central part of Marion County in 1882. This bridge was probably built at that time. It is a three span, wrought iron, Pratt through truss manufactured by the Carnegie Steel Company. The Wabash, St. Louis and Pacific Railroad, the Wabash Railroad, eventually acquired the D&S and this bridge. It remained in use as a railroad bridge until about 1946 when the county acquired the bridge and the right-of-way for a county road. They rehabilitated it in 1951, replacing part of the substructure. The bridge was listed on the National Register of Historic Places in 1998.
