Ship Channel Bridge Reopens After Major Renovation
TORONTO – The Toronto Port Authority has announced the completion of winter construction on the Ship Channel Bridge, which is now open to marine traffic. This extensive renovation project, initiated in March 2022, aims to modernize the aging lift bridge, ensuring the continued transport of essential bulk commodities to the Port of Toronto.
Bridge Rehabilitation: A Multi-Phase Project
The Ship Channel Bridge, located south of Polson Street, is a vital structure that facilitates both vehicular and marine traffic. Originally constructed in 1931, the bridge features a 37-metre-long Warren Through Truss Bascule span, which operates using counterweights, alongside a 43-metre-long steel girder approach span on both ends. The bridge’s total length is 123 metres, supported by concrete abutments resting on timber piles. The north end houses 750-tonne concrete counterweights that enable the bridge to pivot, allowing ships to navigate the channel.
This multi-phase rehabilitation project is crucial for maintaining the flow of bulk materials such as road salt, cement, and aggregates. The first phase, completed in March 2024, involved the rehabilitation of the north and south roadway approaches. The second phase, set to finish by March 2026, will focus on structural steel repairs, cleaning, and coating. The final phase will replace outdated mechanical and electrical lift systems and complete the remaining cleaning and coating work. Most of this work will take place during winter months when the bridge is closed to marine navigation.
Future Benefits for the Port of Toronto
The modernization of the Ship Channel Bridge is expected to yield significant operational and environmental benefits. According to the port authority, the upgrades will enhance the Port of Toronto’s capacity to handle increased cargo tonnage, boost shipments of heavy single components, and accommodate a higher volume of cruise ship passengers. This will also lead to better utilization of existing terminal warehouses and facilities.
In an average year, the Port of Toronto sees over two million tonnes of cargo transit through its facilities. The completion of this project not only ensures the bridge’s operational efficiency but also positions the port for future growth and increased economic activity in the region. The entire modernization effort is projected to be fully completed by 2028, marking a significant milestone in the port’s infrastructure development.
