The Newton Street Bridge is a historic bridge carrying Newton Street over the Charles River in Waltham, Massachusetts. The stone arch bridge was built in 1877 on the site of Waltham's first bridge, which was built c. 1761–62. It was designed by Hiram Blaisdell, a specialist in the design of masonry bridges. It consists of three elliptical arch segments on granite piers. The arches are formed of granite voussoirs, and the facing of the bridge is predominantly rough rock. It is the only 19th-century bridge in Waltham to escape significant alteration.{{cite web|url=https://mhc-macris.net/details?mhcid=wlt.900|title=NRHP nomination for Newton Street Bridge|publisher=Commonwealth of Massachusetts|access-date=2014-04-29}}
