Hopefully a rail trestle qualifies as a bridge.
This is the Salmon River trestle, on the CNR mainline in northwestern NB, near Grand Falls. At 4600 ft in length and 200 ft in height, it is both the highest and longest rail trestle in all of eastern Canada.
I took this photo today. Happily just as we arrived at the trestle, a CNR freight train bound for Moncton and Halifax happened to be passing over it.
