The 1928 Iowa Hill Road Bridge


The 1928 Iowa Hill Road Bridge is a derelict structure located in the Sierra Nevada Mountains of Placer County, California.  The 1928 Iowa Hill Road Bridge can be found between the communities of Colfax and Iowa Hill.  The 1928 Iowa Hill Road Bridge is a wire suspension structure which spans the North Fork American River.  The 1928 Iowa Hill Road Bridge was replaced by a modern span and converted to pedestrian use following floods during 1963.  




Part 1; the history of the 1928 Iowa Hill Road Bridge

During 1853 gold was discovered at what to become Iowa Hill.  The gold mining claims soon led to a small community known as Iowa City being established.   By 1854, Post Office Service began at the mines of Iowa City.  By 1856 gold production at Iowa City was estimated to be around $100,000.  Iowa City was burned in fires during 1857 and 1862 but the community was rebuilt with more modernized structures.  

The location of Iowa City can be seen as "Iowa Hill" on the 1873 Bancroft's Map of California.  Iowa Hill is shown to be a short distance east of Colfax in rural Placer County with no major roads connecting the communities.  


Iowa Hill can be seen connected to Colfax via a road (now Iowa Hill Road) over the North Fork American River on the 1882 Bancroft's Map of California.  


In 1901 the Postal Service officially changed the name of Iowa City to "Iowa Hill."  Iowa Hill Road can be seen in great detail of the 1914 C.F. Weber Map of Placer County.  Iowa Hill Road is shown with a bridge crossing the North Fork American River, it is unclear what type of span this was.  


Iowa Hill burned for a final type during 1920.  Though diminished by fire and the decline mining the community of Iowa Hill persisted.  During 1928 a then new wire suspension bridge was constructed along Iowa Hill Road at the North Fork American River.  The location of the 1928 Iowa Hill Bridge can be seen along Iowa Hill Road on the 1935 Division of Highways Map.  Iowa Hill Road is noted to be a major Placer County road.

During February 1963 the 1928 Iowa Hill Bridge was partially washed out by floods on the North Fork American River.  A new bridge was erected directly to the south as the new alignment of Iowa Hill Road.  The 1928 Iowa Hill Bridge was subsequently retained as part of the Mineral Bar Campground.

Horace Wilkinson Bridge (Baton Rouge, LA)

Standing tall across from downtown Baton Rouge, the Horace Wilkinson Bridge carries Interstate 10 across the lower Mississippi River between West Baton Rouge and East Baton Rouge Parishes. Unusually, the bridge is actually named for three separate people; three generations of Horace Wilkinsons who served in the Louisiana State Legislature over a combined period of 54 years. Constructed in the 1960s and opened to traffic in 1968, this is one of the largest steel bridges on the lower Mississippi. It’s also the tallest bridge across the Mississippi, with its roadway reaching 175 ft at the center span. Baton Rouge is the northernmost city on the river where deep-water, ocean-going vessels can operate. As a result, this bridge is the northernmost bridge on the river of truly gigantic proportions. Altogether, the bridge is nearly 2 ½ miles long and its massive truss superstructure is 4,550 ft long with a center main truss span of 1,235 ft. The Horace Wilkinson Bridge is one of the largest

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which

Natchez-Vidalia Bridge (Natchez, MS)

  Located about halfway between Baton Rouge and Vicksburg near the city of Natchez, the Natchez-Vidalia Bridge crosses the lower Mississippi River between southwest Mississippi and northeastern Louisiana at the city of Vidalia. This river crossing is a dual span, which creates an interesting visual effect that is atypical on the Mississippi River in general. Construction on the original bridge took place in the late 1930s in conjunction with a much larger parallel effort by the U.S. Army Corps of Engineers to strengthen the area’s flood protection and levee system along the Mississippi River. One of the more ambitious aspects of this plan was to relocate the city of Vidalia to a location of higher ground about one mile downriver from the original settlement. The redirection of the river through the Natchez Gorge (which necessitated the relocation of the town) and the reconstruction of the river’s levee system in the area were undertaken in the aftermath of the Great Flood of 1927, wh
