History

In its earliest years, Arlington was a commercial stop along the Overland Trail. Founded circa 1860, it began with the establishment of a bridge and stage stop at the crossing of Rock Creek, after which it was named until the early twentieth century. In 1983, the community was listed on the National Register of Historic Places as a historic district for its nineteenth-century significance. In 1882, a post office was established at Rock Creek under the name of "Rock Dale." Except for a gap in 1924 and 1925, a post office with the name of Arlington was operated in the community from 1902 to 1943.
