Deconstruction of the span’s west cantilever section will begin in late November 2022 and continue until spring 2023.
Nearly 580 steel components to be cut and lowered
579 steel components remain to be cut apart and lowered onto the jetty during work on the west span (seaway dike area) of Section 6.
Steel reinforcements and two temporary support systems were installed above and below the existing structure. This equipment will allow the structure to be cut into two sections to deconstruct them from the center towards the pillars.
The 5 steps of a lifting operation:
- To lift a component from the bridge, engineers have to identify and calculate the weight to be lifted.
- Once the weight is determined, cutting lines are painted onto the component.
- The component is attached to a crane, and crews on the bridge deck cut the steel into pieces.
- Finally, the component is lowered and placed on the jetty by the crane.
- The materials are sent to authorized recycling centres.
