I'm fairly sure that there is no bridge there. Current OS mapping shows a path down to the river at NH 011 481 but no bridge.
The last time I was there was 2003, walking the North to the Cape route, and I remember from my planning that the bridge had been lost some years before. And this [1] report from 2007 mentions there being no bridge over the Carron near the station: not very specific, but I think its the one you're referring to. Given the existence of the bridge to the east of Craig, I'd be surprised if it had been rebuilt.
