Elkridge Information
Elkridge is located in Howard County, Maryland. The population was 22,042 at the 2000 census. Founded early in the 18th century, Elkridge is located at the confluence of three counties, the other two being Anne Arundel and Baltimore counties. It is bordered on the north by Catonsville, on the east by Linthicum and Baltimore-Washington International Airport, on the south by Dorsey, and on the west by Ellicott City and various small communities between it and Columbia.
Elkridge had a rich history of industries including pig-iron forging, basket weaving, paper, cotton and grist milling, as well as employment from the B&O Railroad. The Thomas Viaduct, located over Levering Avenue at the entrance to the Patapsco Valley State Park, is the oldest stone curved bridge in the world. Built in 1833, its architect was Benjamin Latrobe, Jr. The B&O first used horse-drawn coaches in relays, hence Relay Station was added. The viaduct also carried the Tom Thumb, and the first telegraph message from Washington, D.C., stating "What has God wrought?" was wired across.
