The image is a photograph of a plaque on a concrete wall. The plaque is rectangular in shape and has a dark brown color. It is made of metal and is mounted on the wall with screws. The text on the plaque reads "City of Baltimore Department of Public Works Rehabilitation of the Hanover Street Bridge, Thomas J. D'Alessandro, Mayor, 1971". The plaque appears to be old and weathered, with some rust and peeling paint visible on the surface. In the background, there are trees and a grassy area.
