Located in southeastern Harford County, Edgewood was established in the mid-1800s as a small village around a train station. It remained small until 1917, when the government took over thousands of acres to create the Edgewood Arsenal military complex. Thousands came to build the arsenal on land previously known for having fertile farms, gentlemen's waterfowl hunting clubs, and one of the earliest meeting places for Methodists in America. World War II brought an even greater increase in military personnel and civilians. Later, numerous housing developments replaced obsolete off-post government buildings. The creation of Route 40 through Edgewood in 1939 and 1940 and the Edgewood exit on Interstate I-95 in 1963 brought travelers and spurred new business.
