Bridges to Somewhere

A cool article from Infrastructurist.com that my friend Carter sent me about a new, emerging form of bridge structuring started me thinking. As of right now, its cost is comparable to other similar forms of bridge...at least until you take into account that the new carbon fiber/concrete supports would create a bridge that has a lifespan 2 or 3 times longer than standard concrete and steel structuring.
Pittsburgh, as the city of bridges (more bridges found in Pgh metro area than elsewhere, would be wise to keep this new technology in mind as major access bridges need replaced >(cough, Cupple's Stadium bridge, cough)

This is also something that might be an option as the "T-line" expands, possibly replacing the need..err..desire to dig A FREAKIN' TUNNEL UNDER THE RIVER!...ok, done.

Anyway, (caution, thought experiment)the North Shore Connector could lead to a possible extension to Neville Island. And then, who knows, the airport...I think it's not as crazy as it sounds...at least compared to the Airport-to-Downtown Maglev money pit. At least this idea would be a possible boost to both Neville Island and maybe McKees Rocks, although someone of better means would have to do the rough figures on that one.
Anyway, I just thought it was cool, plus some food for thought.
