Rehabilitation of this triple barrel stone arch historic bridge over the Charles River included installation of concrete filled arch saddles, repairs to masonry arches, and concrete repairs to the existing substructure. The foundations were strengthened by coring concrete-filled micro-piles through the existing stone piers and abutments. Work also includes roadway reconstruction, earth excavation, significant utility coordination and improvements. Amenities, including ornamental lighting, railings, and benches, will be added to the bridge.
