2019 Map of Relay

About this map

The Patapsco River valley serves as the central corridor for this 2019 survey, tracing the intricate boundaries where Baltimore, Howard, and Anne Arundel counties meet. The landscape is a dense network of suburban residential communities such as Arbutus, Linthicum, and Elkridge, interconnected by major transit routes and the historic B & O RR. A significant portion of the area is occupied by the modern footprint of the Baltimore/Washington International Airport Thurgood Marshall, yet traditional landmarks remain, including the structural legacy of the Thomas Viaduct and numerous established burial sites like the United Hebrew Cem and Arbutus Memorial Park. The map captures the continued relevance of old settlements like Relay and Saint Denis, which developed at critical junctions of the river and rail, while showing the extensive trails of the Grist Mill Trail and Ridge Trail winding through the river valley parks.
