About this file
This document package includes design plans and calculations for the rehabilitation of the Northern Canal Pedestrian Bridge in Lowell, Massachusetts. The National Park Service is soliciting bids under solicitation number 140P4321R0018 to replace all structural elements of the bridge with the same size and material as the original construction. Key elements to be replaced include railings totaling 170 feet, 12 bearing devices totaling 61.6 inches, three girders totaling 977 inches, timber decking totaling 81.4 feet by 7 feet, and cleaning and repainting of approximately 600 square feet of structural steel. The calculations provided support that no new design or structural capacity analysis is required given the like-for-like replacement scope of work. The involved federal agency is the Department of the Interior National Park Service Northeast Region.
