Detroit River Railroad Tunnel

tunnel, Canada-United States

Quick Summary

The Detroit River Railroad Tunnel is a subaqueous tunnel that connects Detroit, Michigan, in the U.S., with Windsor, Ontario, in Canada, under the Detroit River. This tunnel was one of the first major applications of the immersed-tube method for subaqueous tunneling. This method involves prefabricating long tube sections, towing them to the site, sinking them in a dredged trench, and connecting them. This technique was chosen for the Detroit River Railroad Tunnel to avoid the high costs and risks associated with operating a shield under high air pressure. The Detroit River itself forms part of the boundary between Michigan and Ontario and connects Lake St. Clair to Lake Erie. The river is a busy waterway for both pleasure craft and Great Lakes shipping.12
