Big Becky to break through Friday 13
NIAGARA FALLS, ONTARIO - The Niagara Tunnel Project will hit an important milestone May 13 when Big Becky, the world's largest hard rock tunnel boring machine "breaks through" to daylight after a 10.2 kilometre journey beneath Niagara Falls.

The tunnel mining is a major component of the project and tunnel-mining tradition calls for a celebration when the mining is completed.
