US Route 1

America's Main Street, US Highway 1, Baltimore Avenue, Washington Boulevard--there are many names for the link between Baltimore City and Washington, DC. Connecting residential communities and commercial crossroads clustered along both sides of this historically important artery of transportation, this road has spanned three centuries of transportation, communication, and community development. From the earliest ships in Elkridge and Bladensburg to modern communities supporting the Washington/Baltimore region, Route 1 has been a vital part of this history.
