This major rehabilitation project was fast-tracked from predesign to substantial completion in only 12 months! During a standard OSIM inspection, it was identified that this structure was experiencing a significant increase in deterioration of the exposed deck. Bridge Check Canada conducted a detailed condition survey to determine the extent of deterioration. This led to a cost-benefit analysis of either completing deck repairs or replacing the entire deck structure. Based on the anticipated extended life of the deck and bridge, it was optimal to replace the entire deck at this time, convert the deck to semi-integral, and remove the expansion joints entirely. The work also included jacking of the girders to replace the bearings and repair the girder ends. New curbs, barriers, end walls, spillways, and waterproofing and asphalt were installed above the new concrete deck in accordance with the MTO Structural Manual, OPSD, and OPSS. This is a good example of high-quality work that can be done in a short period of time, on schedule and on budget, with a good contractor. VALLEE completed the design, drawings, tender, and contract supervision and administration for the bridge rehabilitation, and coordinated with County staff throughout the project.
