Lots of big jackhammers.

Knocking down the deck of the old bridge

This is what's left of the north end about 2 hours after they started.

The bridge built in 1939 was torn down so they can widen the QEW which runs under it. The work was all finished in one night from midnight to about 10 am the next day.
Now I hope they can just finish the widening to 6 lanes before they need to go to 8 lanes. After all the only possible solution to traffic congestion is more paving.
Oh the old bridge by the way, used to contain a lane for the rail trolley that used to run from Port Colborne through the peninsula to Port Dalhousie.
