Here's a thought for you, most bridges you drive across deflect an inch or two all the time if heavily loaded. I'm guessing they probably did check with the engineer before they crossed that one though.

I know, its not really that big of a problem, the bridge is simply doing its job. But look at the railings in the last pic. I could be up there with everybody else, but you cant tell me that you wouldnt feel a little odd seeing that railing flex, I know I would.

Steel is designed to deflect under load, a whole lot more than concrete .. the bridge is doing its job. Sure looks scary, but any engineer will tell you that the deflection is allowable.

The really amazing part that most people don't see .. is how much a long bridge shrinks in the cold, and grows on a real hot day. Many long steel bridges have rollers or hinges one end, to allow for the movement, which can be anywhere between 2 and 8 inches.

Sydney Harbour Bridge spreads and shrinks up to 7 inches, and the arch, rises and falls up to 7 inches, just with heat and cold contractions. I'll wager that Canadian bridge does some sizeable shinking and growing between the depths of a Canadian winter and the heat of a Canadian summer .. :)

Quite amazing. What the *ell is it?

and dont say a truck hauling a wide load :D

That's a coker bound for the CNRL Horizon Project. It's basically a major part of the process to remove excess carbon from the oil during the upgrading process. Much more detailed than that, but it's easier to understand like this.
