Exton is positioned at the intersections of U.S. Route 30 (formerly called Lancaster Road) and PA Route 100. These roads were major transport routes to and from Philadelphia and Pottstown.

Though the society has since disbanded and the buildings are owned by another company, the structures remain an Exton landmark.
