History

The county’s transport origins trace to colonial-era routes like the Braddock Road and the Great Wagon Road, which facilitated westward migration toward Wrightsville, Pennsylvania and Hagerstown, Maryland. During the 19th century, the advent of the Baltimore and Ohio Railroad and the Western Maryland Railway reshaped settlements such as Frederick, Maryland, Brunswick, Maryland, and Hagerstown. Civil War movements, including the Battle of Antietam and the Gettysburg Campaign, relied on roads and rail lines through Frederick County and influenced post-war reconstruction policies enacted by the United States Congress. Twentieth-century projects like the construction of Interstate 70 in Maryland and expansions connected the county to the National Highway System and to projects overseen by the Maryland Department of Transportation. Historic preservation efforts involve the National Register of Historic Places listings for covered bridges and portions of the Chesapeake and Ohio Canal corridor.
