Bridge Jacking – King Road, Burlington

Western worked with the City of Burlington, CN Rail and other contractors to complete one of the largest ever bridge hydraulic jacking projects in Canada. The bridge in question weighed approximately 5 million pounds and was installed over a Thanksgiving weekend with minimal disruption to train and roadway traffic. In order to reduce friction forces and enable minimal equipment, an air system was installed, which literally lifted the bridge 0.25″ off the ground and released the tunnel from the concrete form below.
