Etobicoke Creek Rail Bridge Replacement

‍ Harbourside Engineering was retained by Demathieu & Bard Construction to design a versatile, modular gantry system to replace the 122‑year‑old Etobicoke rail bridge for Metrolinx, which aimed to modernize a critical commuter corridor. The gantry enabled the safe removal and installation of bridge spans during three short (51‑hour) weekend closures. This innovative approach reduced disruptions and avoided the environmental impacts of traditional crane-based methods, delivering significant benefits for commuters of the busy Lakeshore West Line.
