James Barney Marsh was an American engineer and bridge designer. He patented a new design for arch bridges. Marsh gave Archie Alexander, the first African-American to graduate as an engineer from Iowa State University, his first job. Marsh worked in the bridge building business for over 50 years, and several of his bridges are listed in the National Register of Historic Places.
The Sutliff Bridge is a bridge over the Cedar River at Sutliff, a Johnson County community near Lisbon, Iowa, United States. A Parker truss bridge, it was built in 1897 and 1898 at a cost of approximately $12,000. J. R. Sheely was the engineer for the original Sutliff Bridge. After a modern replacement was built over the Cedar in 1983, the bridge was slated for destruction, but it was ultimately saved, and on May 15, 1998, it was added to the National Register of Historic Places.
The Burlington, Cedar Rapids and Northern Railway (BCR&N) was a railroad that operated in the United States from 1876 to 1903. It was formed to take over the operations of the bankrupt Burlington, Cedar Rapids and Minnesota Railway, which was, in turn, the result of merging several predecessor lines, the construction of which began in 1869. The corporate headquarters were in Cedar Rapids, Iowa, and it had operations in Iowa and in Minnesota. It was succeeded by the Chicago, Rock Island and Pacific Railway.
The Fremont Mill Bridge near Anamosa, Iowa was built in 1873. Its superstructure was designed and built by Massillon Iron Bridge Company and its foundations were built by James Milne. It is a wrought iron bowstring through arch bridge.
The Pine Mill Bridge is an historic structure located in Wildcat Den State Park in rural Muscatine County, Iowa, United States. It was built in 1878 near the Pine Creek Gristmill, the only place in Iowa where a mill and bridge combination remains in place. The bridge was listed on the National Register of Historic Places in 1998 as a part of the Highway Bridges of Iowa MPS.
The Snider Bridge is located west of Corning, Iowa, United States. It spans Kemp Creek for 119 feet (36 m). In June 1885 the Adams County Board of Supervisors received 17 petitions for new bridges, including one from George Snider. The board decided to erect iron bridges for the longest two spans, including this one. They awarded a contract for both bridges to Reeve, Ward and Keepers of Clinton, Iowa for $1,451.00. This span was completed later in the year. The pinned Pratt pony truss continues to carry traffic on the gravel road over the creek. It was listed on the National Register of Historic Places in 1998.
The Indian Creek Bridge is a wrought iron bridge, built about 1880 to the east of Cedar Rapids, Iowa. The bridge crosses a tributary of the Cedar River in Linn County. It was designed and built by the Wrought Iron Bridge Company (WIBCO) of Canton, Ohio as an eight-panel pin-connected through truss in an unusual double-intersection Pratt design.
County Line Bridge is a historic structure located in a rural area west of Columbus Junction, Iowa, United States. The Louisa County Board of Supervisors approved the petition of Thomas Anwyl in April 1893 to build a bridge over Long Creek on the Louisa-Washington county line. They awarded a $1,174 contract to the Gillette-Herzog Manufacturing Company of Minneapolis to build two bridges. The second span was the Gipple's Quarry Bridge over Buffington Creek in Elm Grove Township. The bridge span is supported by cast iron columns that were manufactured by the Cast Iron Pile and Bridge Company of Keosauqua, Iowa. The steel components were rolled by Carnegie, Gillette-Herzog in Pittsburgh. The pony truss bridge is typical of those built in the same era in Iowa, however, like Gipple's Quarry Bridge it has an unusual lower chord configuration with end panels that slope downward from the bearing shoes to the center panels. It has subsequently been abandoned. The bridge was listed on the National Register of Historic Places in 1998.
The Mill Creek Bridge is located north of Cherokee, Iowa, United States. It spans Mill Creek for 207 feet (63 m). On June 24, 1891, a disastrous flood along the Little Sioux River and its tributaries wiped out nearly every bridge in Cherokee County. The following month the county board of supervisors signed a contract with the George E. King Bridge Co. of Des Moines for 17,650 to replace the bridges. This Pratt truss bridge was fabricated by the King Bridge Company of Cleveland, Ohio. It and a similar span over Mill Creek near Larrabee are the only two that remain. This bridge was listed on the National Register of Historic Places in 1998. A modern concrete span, built just upstream in 2006, now carries the road. The old bridge is closed to vehicular traffic.
The Beaver Creek Bridge was located northwest of Schleswig, Iowa, United States. It spanned Beaver Creek for 134 feet (41 m). Steel was in short supply during World War II as a part of the war effort. Many bridges built across the state were built in this era with timber, especially small-scale bridges. Heavy flooding washed out 27 bridges and culverts in Crawford County in May 1945. The county board of supervisors used emergency funds to build new bridges. They bought several steel superstructures from the Des Moines Steel Company to replace the wash-out spans. The bowstring arch-truss structures appear to have been designed by H. Gene McKeown, a civil engineer from Council Bluffs. This bridge was one of several similar structures built in the county. The bridge was listed on the National Register of Historic Places in 1998, and it was delisted in 2020.
The Storm Creek Bridge is located northeast of Carroll, Iowa, United States. The 64-foot (20 m) span carries traffic on Phoenix Avenue over Storm Creek. This bridge was one of 15 similar spans that Carroll County had built in 1913. The county board of supervisors contracted with the Standard Bridge Company of Omaha to build the Warren pony truss structures that were designed by the Iowa State Highway Commission (ISHC). They were supported by a timber substructure. The bridges became the prototype of what would become the ISHC's standard design. Standard Bridge was paid $29,174 to build all the bridges, which included the costs for this bridge at $2,026. It was listed on the National Register of Historic Places in 1998.
The Storm Creek Bridge 2 is located east of Carroll, Iowa, United States. The 57-foot (17 m) span carries traffic on 190th Street over Storm Creek. This bridge was one of 15 similar spans that Carroll County had built in 1913. The county board of supervisors contracted with the Standard Bridge Company of Omaha to build the Warren pony truss structures that were designed by the Iowa State Highway Commission (ISHC). They were supported by a timber substructure. The bridges became the prototype of what would become the ISHC's standard design. Standard Bridge was paid $29,174 to build all the bridges, which included the costs for this bridge at $1,987. It was listed on the National Register of Historic Places in 1998.
The Otranto Bridge was located northwest of St. Ansgar, Iowa, United States. It carried traffic on 480th Avenue over the Cedar River for 170 feet (52 m). The supervisors from Mitchell County contracted with the Chicago Bridge and Iron Company (CBI) to build two bridges in the county. Chicago engineer Horace E. Horton from CBI designed this Camelback through truss bridge. It replaced and older span at the same location, and it was completed in 1899 for $3,257. The Otranto Bridge was one of the few Camelback through truss bridges built in Iowa. It was replaced by a modern bridge and was privately owned before being dismantled.
The Hammond Bridge is a historic structure located west of Hamilton, Iowa, United States. It spans North Cedar Creek for 178 feet (54 m). Samuel B. Hammond, for whom the bridge is named, requested the Marion County Board of Supervisors in January 1894 to build a bridge near his property. In April of that year they examined the site, and in June they contracted with S.F. Collins to build the Howe covered through truss. He completed it later that year. The stream has been channelized so the truss no longer spans the main water flow. In October 1977 a truck accident closed the bridge for two years, and it reopened in September 1979. The bridge was listed on the National Register of Historic Places in 1998. While it remains in place, a newer span was built to carry the vehicle traffic over the creek.
The Green Mill Ford Bridge was a historic structure located northeast of Janesville, Iowa, United States. It spanned the Cedar River for 244 feet (74 m). This Bowstring through arch-truss bridge was originally erected in Waverly, Iowa after the Bremer County Board of Supervisors found the previous timber structure bridge was worn out. It was designed and erected by the King Iron Bridge and Manufacturing Co. of Cleveland. John R. Price and Brothers built the substructure. The total cost for constructing the bridge was $16,000. It remained in service at this location until 1898 when it was replaced by a girder bridge. The bow string trusses were dismantled three years later. One of the spans was erected over the Cedar River in Franklin Township, while the remaining two spans were erected here in Jefferson Township. The Green Mill Ford Bridge was closed to traffic in 1988. The bridge was listed on the National Register of Historic Places (NRHP) in 1998.
The Little Sioux River Bridge is a historic structure located northwest of Spencer, Iowa, United States. It spans the Little Sioux River for 180 feet (55 m). The bridge was originally located at Main Street, south of downtown Spencer over the same river. Two previous bridges had been located at the original location beginning in 1875, with a replacement in 1889. Clay County contracted with Clinton Bridge and Iron Works from Clinton, Iowa in 1900 to build this Pennsylvania through truss span. Completed the following year, it is the rare example of this type of bridge built in Iowa. A concrete arch span replaced this bridge in 1915, and it was moved to its current location the same year. The concrete abutments were built by Thor Construction Company from Cedar Falls, Iowa. The bridge was listed on the National Register of Historic Places in 1998.
Corbett's/Eby's Mill Bridge is a historic structure located northeast of Scotch Grove, Iowa, United States. It spans the Maquoketa River for 128 feet (39 m). James S. Applegate established a gristmill near this location in 1858. He was joined by John Corbett, who obtained ownership by 1868 and expanded the operation and added a sawmill. He petitioned the Jones County Board of Supervisors for an iron bridge at this location in 1870. They agreed to pay two-thirds of the construction costs with the final third paid for by local subscriptions. The contract to construct this bridge and a similar span in Monticello was made with Miller, Jamison & Company of Cleveland. Both are single span bowstring truss bridges that were completed in November 1871. This bridge has always been identified with the mill. Samuel Eby acquired it in 1875, and it remained in the family until 1913. The bridge was originally on a loop road that circled behind the mill pond. When County Road X73 was created in 1958 it bypassed the bridge to the south. The bridge has been under private ownership ever since. It was listed on the National Register of Historic Places in 1985.
The Fish Creek Bridge is a historic structure that was originally located east of Salem, Iowa, United States. The span carried Hickory Road over Fish Creek for 50 feet (15 m). It is a small-scale, wrought-iron bridge that the Henry County Board of Supervisors bought from the George E. King Bridge Company of Des Moines in 1893 for $410.80. It was believed to have been fabricated by their parent company, King Iron Bridge Company of Cleveland, and assembled by local laborers. Its historical significance derived from its being an uncommon variant of the Pratt truss. It was listed on the National Register of Historic Places in 1998. Subsequently, the bridge has been replaced at its original location, and the historic structure was moved to Oakland Mills Park.
The Oakland Mills Bridge is a historic structure located in Oakland Mills Park southwest of Mount Pleasant, Iowa, United States. The span carried Hickory Road over the Skunk River for 358 feet (109 m). In July 1876 the Henry County Board of Supervisors decided to locate the bridge over the Skunk River at Oakland Mills. After engineers looked over the proposals, they choose the Missouri Valley Bridge and Iron Company of Leavenworth, Kansas to build the structure. The long-span combination Pratt truss through and pony truss was completed later the same year. The steel components where manufactured by the Phoenix Iron Company of Pennsylvania. It is one of the oldest Pratt through truss bridges in Iowa. Long closed to vehicular traffic, it was listed on the National Register of Historic Places in 1998.
The Chain Lakes Bridge is a historic structure located southeast of Palo, Iowa, United States. It carries a pedestrian trail for 370 feet (110 m) over the Cedar River. The Linn County Board of Supervisors began planning for this span in the early 1880s. They appropriated $20,000 for this two-span Pratt through truss The Wrought Iron Bridge Company of Canton, Ohio, which built bridges in the county since 1879, completed this structure in 1884. The bridge was listed on the National Register of Historic Places in 1998. While it was built to carry vehicular traffic, it is now in a nature preserve maintained by the Linn County Conservation Board.
