1955 Map of Portland

About this map

Kittatinny Mountain dominates the northwestern landscape of this mid-century survey, where the Delaware River cuts a dramatic passage through The Gap. This river valley serves as a critical transportation corridor, hosting the Delaware Lackawanna and Western RR alongside the riverbanks. The settlement patterns reflect the era's infrastructure, with Portland and Columbia connected across the water. Moving inland, the landscape is dotted with smaller communities and rural infrastructure like the Vail Sch and Hainesburg Sta, indicating the importance of rail access to the farming and residential areas of Knowlton and Blairstown townships.
