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

The Region of Niagara is in the process of replacing the nearly 100-year-old Burgoyne Bridge in the City of St. Catharines, Ontario, Canada. Two key factors were the desire to create an iconic or landmark bridge, and the necessity of maintaining traffic throughout construction. The paper discusses technical considerations including corridor selection, alignment, staging, detailed geometry, the integration of bridge construction and bridge demolition, the consideration of adjacent properties and businesses, and connections to local roadways. The development of the new bridge concept and preliminary design are also explored, including reference to inspirational projects elsewhere, and to the history of heritage bridges at the site. Finally the resulting 330m long twin structural steel box girder viaduct bridge, including a single 125m structural steel arch span, is put into context from technical, environmental, and stakeholder perspectives.
