My thoughts echo the above, especially Javan and Salem.
Jerry Fisk and a few other smiths down south have custom made bridge anvils (IIRC, I saw a photo of Jerry's and it even has his name in it).
But for general forging, a bridge is pretty much the exact OPPOSITE of what you would want. An efficient anvil has the majority of its mass under the working area.
Now just to contradict myself, I would love to have that anvil in my shop to look at...just because I think it's super cool looking. But I doubt I'd use it much, if at all, to forge blades on.
