Overview
The objective of this project is to update two “towerless” vertical-lift bridges, built between 1911 and 1915, to best serve the nearly 5.8 million passenger trips across them each year. The first bridge carries NY Route 19 (Main Street) over the Erie Canal in Brockport, NY. It has a total length of 155 feet with a 130-foot vertical-lift span. The second carries NY Route 98 (North Main Street) over the Erie Canal in Albion, NY. It has a total length of 132 feet with a 115-foot vertical-lift span.
As the prime consultant, M&M provided a full inspection of all structural, mechanical, and electrical components for each bridge. The inspection findings were the primary basis for the scope of rehabilitation documented in the Bridge Rehabilitation Report (BRR), which included a Bridge Rehabilitation Justification Report (BRJR). Ongoing final design work includes load rating the trusses, full replacement of truss bottom chord elements, select replacement of other truss elements and full replacement of the floor systems. Reinforced concrete counterweights will be replaced with smaller steel counterweights to allow for improved access and safety within the lift pits. M&M is also overhauling all mechanical and electrical equipment including the lifting mechanism components and control systems.
