Chief William Commanda Bridge

This project consists of the rehabilitation of Chief William Commanda Bridge in Ottawa and Quebec.

TRANSPORTATION

The project is a $22.6 M rehabilitation to convert the unused rail structure into a pedestrian and cycling pathway from Ottawa to Western Quebec.

It includes reconstruction of the timber deck, replacement of the bearings at each span, and reinforcement of the masonry substructure.

Entuitive is supporting Aecon with Construction Engineering services to complete the rehabilitation work. Entuitive also completed the design of the jacking and shoring system along with the temporary works, including barge access on the island, pedestrian enclosure over the Ottawa river trail, and pedestrian railing installation procedure.

The structure was built in 1879 with the superstructure reconstructed in 1926. The bridge is formed by two structures (north bridge and south bridge) separated by Lemieux Island – comprising six spans in the south structure and seven spans in the north structure with a total structure length of 989 meters.
