Thinking that far ahead for the Fraser river might be a little difficult due to all the variables. It doesn't make a lot of sense to spend what could be quite a bit of extra money (the redesign of the Steveston Highway interchange would be insane if the bridge were much taller) on just a maybe. Other factors could come into play too, like what will be the sea level over the next 50 years. Or will global warming lower the river level making it a hazard to navigate. How much extra pollution would be created by longer steeper grades on the bridge approaches, and what affect would that have on traffic models? Will there even be an LNG export industry in the future?
It might make a lot more sense to move the pipeline to another port if the alternative is designing an impractical and expensive bridge to accommodate a maybe.
