Western Mechanical’s Millwright Division developed a unique, new method of Rapid Bridge Replacement for railroad bridges. By “launching” each bridge span using an overhead gantry crane system, Western was able to replace each span on a bridge in Montmagny, Quebec in less than 3.5 hours. Western’s method introduces tremendous cost savings compared to alternative installation methods. The speed of the method used allows for the replacement of bridge spans within strict railroad time blocks without obstructions to the train schedules. Below is a time lapse videos of Western’s crew and equipment in action.
