Niagara Tunnel’s concrete lining done
NIAGARA FALLS, ONT.
The concrete lining for a 10.2-kilometre long tunnel beneath Niagara Fall is now complete, marking a significant milestone for the Niagara Tunnel Project.
When completed in 2013, the 14.4-metre-wide tunnel will allow additional water from the Niagara River to flow to the Sir Adam Beck Generating Station at a rate of 500 cubic metres per second.
This will increase output by about 1.6 billion kilowatt-hours, enough electricity to power 160,000 homes.
The tunnel liner wall is 60 centimetres thick and made of cast-in-place concrete. About 500,000 cubic metres of concrete was used to line the tunnel — more than enough to build a sidewalk from Windsor, Ont. to Quebec City.
The Niagara Tunnel Project is the largest renewable energy project of its type under construction anywhere in the world and has brought approximately $1 billion in economic benefits to the region.
