The Algonquin Island Bridge is the primary and only fixed access for pedestrians, bicycles and service vehicles between Algonquin Island and Ward’s Island on the Toronto Islands. Originally constructed in 1938, the structure was rehabilitated in 1998 with ongoing maintenance. 

The bridge supports a watermain along the west side and a gas pipeline underwater below the bridge deck. Currently there is a load restriction of 12 tonnes due to the aging structure and it does not meet City's full service vehicle requirements. The bridge structure is in need of major repairs or possible replacement. 

This study will identify and evaluate how to ensure that a link between Algonquin and Ward’s Islands is maintained, while accommodating all users, both over and under the bridge, and essential vehicles. As options (including a new crossing) are considered, the heritage value of the existing bridge structure will be an important consideration.
