Limestone–Gillespie Portage Border Crossing

South of the crossing, one hundred yards from the border, is a decommissioned Nike missile base that is now an auto repair shop.

[2] The United States border station originally included the main building and two residences, located to its rear.

The main building is a wood frame structure, a single story in height, with a side gable roof and flanking wings, each of which house two garage bays for performing inspections, and is located quite close to the border.

[3] Prior to the construction of this station, customs and immigration formalities would have taken place in the nearest town.

With the advent of increased automobile traffic in the 1920s, as well as the need to interdict the movement of contraband liquor due to Prohibition, the federal government realized the need for border stations where immigration formalities and vehicle inspections could be performed close to the border, and consequently planned the construction of a series of such stations.
