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. It spans the Black River, bringing an army road, now Indian Route 9, over the river from Fort Apache to the railroad at the former town of Rice, Arizona (which is now within San Carlos, Arizona).
