Allegany County

Allegany County was created from Washington County in 1789, and Cumberland became its seat. Transportation became a defining part of the local story: the National Road opened a major westward connection in 1818, and the Chesapeake and Ohio Canal reached Cumberland in 1850. Frostburg's incorporation in 1839 adds another community milestone. Seen together, these dates describe a county shaped by changing ways of moving goods and people through the terrain of western Maryland.

Cumberland is a useful starting point for a visit centered on transportation history. Explore the relationship between the city and its historic routes before adding Frostburg or another county destination. The National Road and canal belong to different eras, making them complementary ways to understand regional connections. Allow time for the geography as well as the landmarks: the river boundary and mountain setting help explain why these routes mattered so much.
