As roads and bridges in Canadian cities suffer from the effects of harsh weather, heavy traffic, road salt and acid rain, a new cross-border bridge in Cornwall, Ontario stands strong. Built from a new class of concrete, the deck of the Canal Bridge part of the Seaway International Bridge system is expected to require significantly less maintenance than most of the other 80,000 bridges across Canada, ensuring safe and efficient travel for the more than 2.3M drivers who use it each year.
