The Bridge War, also called the Red River Bridge War or the Toll Bridge War, was a 1931 bloodless boundary conflict between the U.S. states of Oklahoma and Texas over an existing toll bridge and a new free bridge crossing the Red River. The Red River Bridge Company, a private firm owned by Benjamin Colbert, had been operating a toll bridge between Durant, Oklahoma and Denison, Texas, carrying U.S. Route 69 and U.S. Route 75. Texas and Oklahoma had jointly built a new, free span northwest of the existing toll bridge.
