1909 Map of Mount Airy

About this map

Mount Airy sits at the high point of this Maryland landscape, where the Baltimore and Ohio Railroad crests the drainage divide of Parr Ridge. This survey, conducted shortly after the turn of the century, captures the intricate network of turnpikes and rural settlements across the junction of Carroll, Howard, Frederick, and Montgomery Counties. The transport economy is evident in the transition from the rail-oriented Mount Airy and Woodbine to the older milling and toll-road centers. Along the southern edge, the Patuxent River winds past small industrial hubs like Roxbury Mills, while to the east, the Patapsco River flows through Hoods Mills. The map documents a time when the Poplar Springs Tollgate Turnpike and Taylorville Turnpike remained primary arteries for local commerce and agricultural transit between villages such as Libertytown and Winfield.
