1956 Map of Portland

About this map

The coastal corridor from Portsmouth to Portland serves as the focal point for this 1956 survey, revised in the early 1970s. The map illustrates a region in transition, where the heavy infrastructure of the Boston & Maine RR and Maine Central RR supports a dense network of coastal settlements and inland manufacturing hubs like Rochester and Dover. Beyond the industrial centers of Biddeford and Saco, the landscape gives way to the major water bodies of the interior, including Sebago Lake and the sprawling Lake Winnipesaukee.
