With a diameter of 14.44 metres (as high as a four-storey building), the tunnel is the world’s largest to be constructed in hard rock with a tunnel boring machine.
McNalley Construction was the contractor on the project.
Built to diverting water to the Adam Beck Generating Station at Niagara Falls, the tunnel will help generate enough electricity for 160,000 homes for a century or more.
The project has been featured on TV on the Discovery Channel, National Geographic and Learning Channel. Paul Moorhouse, P.Eng. of Hatch wrote about the technical aspects in Canadian Consulting Engineer magazine’s February issue. Click here.
