New Bridge was founded on the banks of Eagle Creek near an important bridge built across the stream in pioneer times.Joseph Gale was the first postmaster of New Bridge post office, which ran from 1878 until 1967. The town was originally in Union County until 1901, when the boundaries were changed to eliminate the panhandle in which New Bridge was located. New Bridge was platted in 1908, "only after irreversible decline had set in". New Bridge sold agricultural products from the Eagle Valley to miners near Sparta. It had a fruit and vegetable cannery, a box factory, and a packing shed for apples. The decline of New Bridge was due in part to nearby Richland being platted in 1897.
