Kendrick Street/Nahanton Street Bridge Rehabilitation
Needham and Newton, Massachusetts
The Town of Needham and the City of Newton jointly own the bridge carrying Kendrick Street/Nahanton Street over the Charles River, which serves as the border between the two municipalities. The bridge is a three-span continuous rolled steel beam bridge originally constructed in 1959 and re-decked in 1988.
The two municipalities retained BETA to perform a bridge replacement investigation and evaluation of the structure; recommend repairs geared towards extending the structure’s service life; design those repairs; prepare and file appropriate regulatory permits; prepare construction documents; and provide construction services, including full-time inspection.
In addition to a hands-on inspection by our qualified inspection team, the investigation included an underwater inspection, concrete testing of the substructure, sonic/ultrasonic testing of the concrete deck, hydraulic and scour analyses, and a fatigue analysis.
The repair program included partial-depth repairs to the concrete deck, repairs to steel cover plates, replacement of deck joints, replacement of bridge bearings, repainting of structural steel, and repairs to riprap slope paving.
