2019 Map of Union Bridge

About this map

The town of Union Bridge and its surrounding countryside reflect a heritage of milling and early Maryland settlement along the Carroll Co Frederick Co border. This area is defined by the winding course of Little Pipe Cr and Big Pipe Creek, which historically powered local industry at sites like McKinstrys Mill, Crouse Mill, and Simpsons Mill. The rural landscape is dotted with small communities including Middleburg, Keymar, and Johnsville, each maintaining its own local character and deep roots visible through numerous family and congregational burial grounds such as Pipe Creek Friends Cem and the German Baptist Cem. To the east, the Priestland Valley opens up between Bark Hill and Linwood, while aviation interest is represented by Keymar Airpark and the Flying H Farm Airport in the south.
