Junction is an unincorporated community in Lemhi County, in the U.S. state of Idaho. [1]
Bannock had its start when A. M. Stephenson established a hotel at the site. [1] The community was so named from its location at the junction of Bannock pass road and the Mormon road. [2] A post office called Junction was established in 1874, and remained in operation until 1919. [3]
