Four Indian trails came together at a bend of the Beaverhead River north of the present school building in Twin Bridges. These trails were used by early settlers and freight companies, and helped to establish where the community of Twin Bridges would develop. Judge M.H. Lott came to Montana in 1862, and with his brother John T. Lott settled in the Ruby Valley in 1864. In 1865 they built a bridge across the Beaverhead River, and later built another bridge across the Beaverhead at the Point of Rocks. The Lott brothers continued development of roads and promoted settlement of the town, which was incorporated in 1902, with M.H. Lott as the first mayor.
