Bridgeport was founded in 1900 as a station by the Burlington Railroad and celebrated its centennial in 2000. The town lies on or near many historic trails of the West, including the Oregon, California Mormon, Pony Express, and Sidney-Black Hills Trails. Courthouse and Jail Rocks, south of Bridgeport, were landmarks mentioned in many travelers’ journals. In 1876 Henry T. Clarke built a bridge across the North Platte River three miles upstream from the future site of Bridgeport to improve the trail from Sidney to the gold-mining towns of the Black Hills. Freight from Sidney and gold from the mines crossed the bridge for nearly a decade, and a village called Camp Clarke grew up nearby. The arrival of railroads in the North Platte Valley established Bridgeport and brought increased settlement to the area. Irrigation projects in the early 1900s encouraged agricultural development. Bridgeport became the seat of newly designated Morrill County in 1908, and its economy remains based on agriculture, railroads, and government.
