Enbridge Moves Forward with Rock and Soil Sampling

Enbridge will continue with rock and soil sampling in the Straits this week as it moves its previously land based sampling operation onto the water. 6-inch-diameter holes will be drilled up to 150 feet into the lakebed to determine the best place for the tunnel.The geotechnical work is part of a $40 million investment into pre-construction work and will help to keep the tunnel construction on the proposed timeline.  Once the results of the geotechnical studies are in, tunnel design work can begin as early as 2020.
