CN Rail Bridge Removal

Trenton, Ontario

 

The removal of an out of service railway bridge. A barge was used to float out each section. The sections were brought to shore and lifted off of the barge. The contractor’s unique approach was to use inflatable air bags to lift up the sections off of the peers and then float the sections by barge to a nearby (newly constructed) dock. The methodology expected in the contract was to use a crane on the bridge and dismantle the bridge as the crane retreated off of the bridge.  The contractor’s method ensured that debris from the creosoted rail ties did not fall into the water since it was much easier and safer to dismantle at the dock. Boating traffic in the Trent Canal was also not affected by this approach.
