We overcame harsh geotechnical conditions and traffic issues surrounding the site over a period of three years to build the new 330-m Burgoyne Bridge, which replaces an existing two-lane bridge that had to be demolished before construction could start.
Specifically, this project involved the following work:
Building lightweight fill approaches
Demolishing the existing bridge
Installing lighting and utilities
Performing road work (including road reconstruction)
The new bridge required a 125-m arch span to qualify as a landmark and act as a passageway to the Western Hill community and downtown St. Catherines. Our team met this challenge with flying colours.
Unique geotechnical conditions
We had to pour deep foundations in harsh geotechnical conditions, including soft and variable-strength soil.
Dealing with a water table on bedrock
We had to deal with an artesian water table covering the bedrock, some 25 m below the valley floor.
Managing traffic for three years
Our team had to do their work in phases throughout the project to keep traffic lanes and a crosswalk open to the public, minimizing the impact on the local population.
