Description 

Adams Street Bridge has significance 1) as an example of stone-slab and stone-arch construction, once-common bridge-building technologies; 2) as the work of Gridley Bryant, a notable 19th-century engineer and inventor who designed and constructed the pioneering Granite Railway; 3) as a contributing element in the Dorchester/Milton Lower Mills Industrial District (listed in the National Register of Historic Places); and 4) as a structure that recalls the important role of the granite industry in the historical development of Milton and the nearby town of Quincy.
