Over the last weekend in October, EXP worked alongside Metrolinx and Mobilinx to deliver the next step in the Hazel McCallion Line, an underpass below the Queen Elizabeth Way (QEW). The progress signifies another milestone in the project’s goal to deliver new, more sustainable and reliable transportation for the growing region.
The weekend work involved the installation of a push box, a hollow and a large concrete box. The push box will create a new underpass along Hurontario Street and, once pushed into place using hydraulic jacks and then paved, will provide the northbound lanes of Hurontario in the future. “The innovative technique of using a push box, an outstanding accelerated construction methodology, involves careful planning. EXP completed the design of the concrete QEW Push Box (open-cut tunnel) which was constructed beside the QEW over a period of a few months. Mobilinx performed significant advanced work to ensure the push box could be completed within one weekend (55 hours in total) thus minimizing traffic disruptions and maximizing the efficiency of the push,” said EXP’s Senior Project George Badawy.
“Our transportation experts in Canada understand the significance of minimizing disruptions for the community. We are proud of the work completed, and we look forward to the lasting impacts of the project,” said EXP’s Senior Project Manager Kevin McNally.
The Hazel McCallion Line is expected to be completed in 2024.
