Safety Hub

The Great Lakes Tunnel will make a safe pipeline even safer by moving a portion of Line 5 out of the Straits of Mackinac, deep below the lakebed.

Safety matters to Michigan…

Get the Facts

  • A study conducted by Michigan state government concluded that the Great Lakes Tunnel reduces the risk of a spill in the Straits to “virtually zero!”

  • The Tunnel’s concrete lining provides a second containment layer to prevent any leak from ever entering the water.

  • The Tunnel will be built using technology that ensures no water, soil, or rock enters the tunnel during construction!

  • Line 5 is continuously monitored for safety. The Great Lakes Tunnel will be, too, before, during and after construction.

  • Line 5 safely transports 22,680,000 gallons of fuel daily!

The Tunnel is by far the safest transportation option.

Without Line 5 and the Great Lakes Tunnel, it would take:

  • 2,100 tanker trucks traveling back and forth over the Mackinac Bridge – every single day.

  • 90 trucks every hour, every day, traveling completely across each of Michigan’s peninsulas.

  • 800 rail cars traversing the entire state – every day!

With Line 5

  • Current safety record, 22.68M gallons per day

  • 24 hour monitoring

With the Great Lakes Tunnel

  • Current safety record, 22.68M gallons per day

  • 24 hour monitoring

  • PLUS “virtually zero”, additional safety monitoring tools, deep below the lakebed / out of the water, second containment layer

Without Line 5

  • None of the safety measures

  • 2,100 tanker trucks

  • 90 trucks

  • 800 rail cars
