The Arnold Transit Company is the longest operating ferry line on the straits of Mackinac. Founded in 1878 by George T. Arnold, the line continues to transport thousands of passengers and tons of freight every year. The record group consists primarily of early financial records, various property interests of Arnold Transit, and the estates of the Arnold family.
The record group consists primarily of early financial records, dating back to 1850, before the company was founded. Other records document the various property interests of the Arnold Transit Company (ATC), and the estates of the Arnold family. The vessels themselves are represented through various certificates, manifests, and logs. Historical advertisements of Arnold Transit have been preserved, as well as promotions of the straits of Mackinac and surrounding area in general. Architectural plans, documents of area organizations, information on competing lines, and a fair number of photographs round out the collection.
The record group is comprised of seven series: Administration, Union Terminal Piers, Topical Files, Area Organizations, People, Visual Materials, and Vessels.
