Learn about the construction of the St Clair Tunnel!

Rail traffic is backed up and at a standstill on a frozen stormy night in the middle of winter. It is too dangerous for the Grand Trunk Railway ferries to make the river crossing in the storm and tomorrow will be lost due to ice jams. The St. Clair River crossing has become a bottleneck and delays are costing money. The solution is digging a tunnel in the soft clay beneath one of the fastest rivers to join Canada and the United States by a ribbon of steel. This was an engineering marvel of its time only to be repeated 100 years later by employing the latest laser guided technologically advanced tunneling machine dubbed “Excalibore” built in Toronto Ontario.
