Burgoyne Bridge Designed to Respect History of Site and to Create a New Landmark

摘要

The Region of Niagara is in the process of replacing the nearly 100-year-old BurgoyneBridge in the City of St. Catharines, Ontario, Canada. Two key factors were the desire to create aniconic or landmark bridge, and the necessity of maintaining traffic throughout construction. Thepaper discusses technical considerations including corridor selection, alignment, staging, detailedgeometry, the integration of bridge construction and bridge demolition, the consideration ofadjacent properties and businesses, and connections to local roadways. The development of thenew bridge concept and preliminary design are also explored, including reference to inspirationalprojects elsewhere, and to the history of heritage bridges at the site. Finally the resulting 330mlong twin structural steel box girder viaduct bridge, including a single 125m structural steel archspan, is put into context from technical, environmental, and stakeholder perspectives.
