Three generations from a family of heavy machinery lovers were among the thousands who filed through the Waterview Connection constructions site yesterday to see Alice, the giant boring machine.
Allen Webber, 40, took along his two young sons Jake, 7, and Luke, 4, and his father, Murray, 73, who secured the tickets.
Mr Webber's father took a poster so the boys could learn all about the $55 million machine and its 700m long conveyor belt that will be used to extract the 800,000cu m of spoil from the twin tunnels.
Mr Webber, from Massey, said it was "awesome".
"The boys had a tonne of fun. They love all that kind of stuff, boys will be boys. I'm a builder and they love looking at all my tools and stuff."
