Crane Assisted Bridge De-launch
Remote British Columbia
As part of a BC pipeline project, these decommissioned bridges needed to be removed – Arch was selected to design the removal methodology.
Solution & Impact
With the crane and excavators already in the area, this simple counterweighted de-launch was designed. The crane assists two excavators to pull the bridge across the abutment and onto the excavated embankment.
Ingenious solutions were provided to optimize the sliding of the bottom flanges on the retained bearing points.
