New St. Clair River segment of Line 5 now in service

‘Textbook execution’ despite numerous obstacles; enhanced safety measures are built in

A new segment of Enbridge’s Line 5 pipeline—installed via horizontal directional drilling (HDD) under the St. Clair River between Ontario and Michigan—was placed into service on July 31, 2020.

The project makes a safe pipeline safer, and delivers on one of seven key actions in a 2017 agreement between Enbridge and the State of Michigan to address the future of Line 5, and protect the waters of the Great Lakes for future generations.

The project entailed replacement of the section of Line 5 crossing the St. Clair River at Marysville, MI. That section, which previously lay on the bed of the river, now crosses far below the riverbed with new, state-of-the-art line pipe.
