Cause

Texas and Oklahoma jointly constructed a free bridge over the Red River in 1931 to replace a private toll bridge operated by the Red River Bridge Company. The company, having been promised $60,000 by the Texas Highway Commission for the old bridge, obtained a court injunction blocking the new span from opening, and Texas Governor Sterling ordered barricades erected at the Texas end.

Event

Oklahoma Governor William Murray declared the new bridge open by executive order on July 17, 1931, citing Oklahoma's territorial claim under the Adams–Onís Treaty. Oklahoma crews demolished the toll bridge approach to force traffic onto the free span, while Murray subsequently declared martial law and personally appeared at the site armed with a revolver; Oklahoma National Guardsmen held both bridge approaches against the injunction.

Consequence

The injunction was dissolved and martial law rescinded on August 6, 1931, and the free bridge opened officially on Labor Day, September 7. The dispute attracted national and international headlines, with Adolf Hitler reportedly interpreting it as evidence of division among American states. A portion of the original free bridge was preserved and relocated to a park in Colbert, Oklahoma, after its replacement in 1995.
