Oil giant Enbridge has selected a team to design and construct a new oil pipeline under the Straits of Mackinac between Lake Michigan and Lake Huron to replace the deteriorating Line 5.
The Canadian company on March 6 announced that Great Lakes Tunnel Constructors, a partnership of Michigan tunnel construction firm Jay Dee Contractors Inc. and the U.S. affiliate of Japanese tunnelling contractor Obayashi Corp., will build the four-mile-long tunnel about 100 ft below the Lake Michigan lake bed. Arup will design the tunnel.
