The Black River Bridge near Carrizo, Arizona was funded in 1911 and built in 1912. It was listed on the National Register of Historic Places in 1988.[1] It spans the Black River, bringing an army road, now , over the river from Fort Apache to the railroad at the former town of (which is now within San Carlos, Arizona).
Indian Route 9 is one of many Indian routes within Native American reservations in the U.S. The bridge, designated ADOT #3128, is owned by the U.S. Bureau of Indian Affairs.[2] It crosses from the Fort Apache Reservation south into the San Carlos Reservation, within in Gila County, Arizona.
It is a deck truss bridge which was fabricated by the Pittsburgh-Des Moines Steel Co. It has three Warren truss riveted steel spans, each 82.0 feet (25.0 m) in length, achieving a total length of 273.0 feet (83.2 m). The roadway is a concrete deck that is 18 feet (5.5 m) wide. The bridge has concrete abutments and wingwalls and solid concrete piers. It has a concrete deck over steel stringers.[2]
The original bridge on those piers was designed by Arizona Territorial Engineer and was completed in 1912 as a timber/iron truss bridge for wagons, employing Howe trusses; the superstructure was replaced by the current steel and concrete system in 1929.[2]
It was deemed significant as one of the earliest public works projects by the Arizona Territorial government, and the only timber bridge that it built.[2]
Further, the 1929-built superstructure "is technologically significant as the oldest of the four multi-span deck trussed trestles" identified in a 1986–87 inventory/study of historic Arizona highway bridges performed for the Arizona Department of Transportation by Clayton Fraser, covering 610 pre-1945 vehicular bridges.[2][3] According to Fraser, the bridge is "one of the most visually striking spans in Arizona" and "represents an important aspect of the state's bridgebuilding history."[2]
A 2002 photo of the bridge is included in a 2008-updated report on Arizona's historic highway bridges.[4]
