Tomorrow morning marks the official christening of Big Becky, a gigantic boring machine that will soon begin its two-year mission of drilling a 10.4 kilometre tunnel about 140 metres under the city of Niagara Falls.
The goal: tap more waterpower for generating electricity. It’s not quite a voyage to the centre of the earth, but the sheer size of the project makes this an historic undertaking in the province.
