Relay
Created in 1830 as a change point, or "relay," for horses hauling the first scheduled railroad cars in the U.S. The first rail link to nation's capital began here. Thomas Viaduct carries the track across Patapsco gorge; completed in 1835, it is the oldest multiple-arch railroad bridge in North America. In the Civil War, Union troops were stationed here to protect this critical junction.
Marker is on S. Rolling Road 0.1 miles south of Francis Avenue, on the right when traveling south.
