The First Avenue Bridge is a historic structure located in downtown Cedar Rapids, Iowa, United States. It carries U.S. Route 151 for 697 feet (212 m) over the Cedar River. The original six-span concrete arch structure was completed in 1920 for $420,000. It was designed by Marsh Engineering Company and built by Koss Construction Co., both of Des Moines. Consulting engineer Ned L. Ashton of Iowa City designed the 1960s remodel. He had all of the concrete work above the original arches torn out and the bridge rebuilt as an open-spandrel structure. The rebuild also included a wider deck to accommodate increased traffic and aluminum railings. While the bridge's original structural integrity has been compromised, this is the first notable concrete spandrel arch reconstruction in Iowa and possibly in the country. The bridge was listed on the National Register of Historic Places in 1998.

The Pittsburgh-Des Moines Steel Company, and often referred to as Pitt-Des Moines Steel or PDM was an American steel fabrication company. It operated from 1892 until approximately 2002 when its assets were sold to other companies, including Chicago Bridge & Iron Company. The company began as a builder of steel water tanks and bridges.

A number of its works are listed on the National Register of Historic Places.
The Cascade Bridge is a historic structure located in Burlington, Iowa, United States. In April 1896 the Burlington City Council approved a proposal to have city engineer S.D. Eaton advertise for plans and estimates for a bridge on Main Street that would span Cascade Ravine. The Cascade Lumber Company had petitioned for the bridge. The city contracted with the Cedar Rapids, Iowa firm of Boynton & Warriner to design the structure and the Milwaukee Bridge and Iron Works to erect the span. The city was responsible for building the concrete substructure. The bridge was completed in the fall of 1896, and is composed of four spans. The span length is 160 feet (49 m), and its total length is 464 feet (141 m). The span is a Baltimore deck truss bridge with Pratt deck trusses at both ends. The structure is supported by stone and concrete abutments with concrete pedestals and a single concrete-filled steel cylinder pier. Over the years the original deck has been replaced, and concrete has been applied to the stone abutments. Otherwise the structure has been unaltered. The bridge was listed on the National Register of Historic Places in 1998.
The Des Moines River Bridge is a historic bridge located southwest of Swea City, Iowa, United States. It spans the Des Moines River for 102 feet (31 m). In February 1916, the Kossuth County Board of Supervisors approved the contract for the Des Moines Marsh Engineering Company to build the bridges. It was designed by the company's engineer James B. Marsh. The 9-panel Marsh fixed arch bridge, also known as a "rainbow arch", was completed in 1916 for $7,150. It features two tapered concrete arches that carry the roadway in between them from hangers. It was listed on the National Register of Historic Places in 1998.

The Rockwell City Bridge is located just east of Rockwell City, Iowa, United States. The 60-foot (18 m) span carried traffic on 270th Street over an unnamed stream. In 1915 Calhoun County requested the Iowa State Highway Commission (ISHC) and Des Moines engineer James B. Marsh to design a bridge for this crossing. The ISHC designed a double span concrete girder structure, while Marsh submitted his patented single-span rainbow arch configuration. They chose the Marsh submission, and contracted with the Iowa Bridge Company to build six bridges for $11,690, which included the costs for this bridge at $4,107.65. Originally built to serve a county road, it was later incorporated into the route for U.S. Highway 20 and carried heavy traffic until the highway was realigned in 1981. While no longer in use, the bridge remains in place just south of the replacement span. It was listed on the National Register of Historic Places in 1998.
The Marsh Rainbow Arch Bridge, also known as the Coon River Bridge and Rainbow Bend Access, is located south of Lake City, Iowa, United States. The 271-foot (83 m) three-span bridge carried traffic on Iberia Avenue over the North Raccoon River. It was designed by Des Moines engineer James Barney Marsh in his patented rainbow arch configuration, and constructed by the Iowa Bridge Company in 1914 for $10,970. It replaced a Howe truss bridge that had been built by the King Bridge Company of Cleveland. That bridge was put in service upstream and remained in use until 1983 when it was taken down. The Marsh arch bridge was bypassed in 1985, and remains in place in a county park. It was listed on the National Register of Historic Places in 1989.
The Mederville Bridge is a historic structure located in the unincorporated community of Mederville, Iowa, United States. It spans the Volga River for 156 feet (48 m).

Clayton County rejected all of the original bids to build the structure when they all came in too high. Six companies bid a second time on the project, and F. E. Marsh and Company of Des Moines won. They completed in the bridge in 1918 for $17,454.32. It was listed on the National Register of Historic Places in 1998. On October 2, 2021, it was the site where Kelsey Bergan and Mark Schutte got married.
The Dunkerton Bridge is a historic structure located in Dunkerton, Iowa, United States. The span carried a local street over Crane Creek for 212 feet (65 m). The three-span, filled spandrel arch bridge was built by the Marsh Engineering Company of Des Moines in 1909. It replaced an older span at a different location. The bridge served as the major entry point into the town from the north. This bridge was also replaced by a newer bridge to the east, and this span now carries pedestrian traffic between Charma Park and Marble Street into downtown Dunkerton. It was listed on the National Register of Historic Places in 1998.
