Abstract:
When designed and constructed in the late 1930s, the Thousand Islands Bridges represented the state-of-the-art in bridge design. Over the life of the structures a number of improvements have been undertaken to upgrade the spans to meet the demands of its users. In 1994, it was concluded that sections of the deck on the Canadian Crossing had reached the end of their life cycle and replacement was necessary. In 1997, the state-of-the-art in construction materials and construction methods rehabilitated the structure using 1930s state-of-the-art in bridge deck technology. The owners and operators of the bridge can reasonably expect a full second life span of the Canadian Crossing well into the next century.
