Centre Street Bridge - Installation 

We would like to thank the City of Calgary, Hatch Ltd. and PCL as partners in this project.

The flood wall for the north end of the bridge and the south end of Centre Street Bridge are each stored on a trolley. The trolley stores the demountable flood barriers, middle posts with back braces and tools. The trolley gets deployed to the entrance and the crew can install the 2.40m flood wall.

Middle post with back brace is installed on top of the anchors (below). 

Anchors are permanently integrated in the road. 

Side channels are permanently attached to the bridge structure. The cover of the side channel is removed and the flood barriers installed between the channels and the middle posts.
