An aging multispan bridge had to be replaced with little interference to river and road traffic without changing its alignment in Trenton, Ontario, Canada. This paper describes how this was done by constructing the new bridge immediately adjacent to the old bridge, demolishing the old, and then sliding the new bridge onto new piers and abutments installed in the existinvg alignment. Such a slide, involving a major continuous bridge and a computer controlled jacking system, was the first in North America. The project involved a high degree of cooperation between the owner, desinger, contractor, specialist contractor and the Ministry of Transportation of Ontario.
