I don't see why not. ; As long as the math works, wood can be used in any type of construction, including bridges. ; It just isn't used for that purpose much anymore due to the high maintenance costs compared to other materials. The existing concrete appears to be spalling which indicates a water problem (water getting into the concrete and then going through freeze-thaw cycles causing the face of the concrete to break off). ; As long as it is limited to surface damage, it can be patched fairly easily after fixing the water problem.
OK, I was just kidding. ; This bridge over our local river has not been used for, well, since I can remember walking past it on my way to school in the 60's. ; The track, ran through town to the depot on the north side of town. ; Interesting enough is that those tracks are gone but the north depot is now an historical site but is still in use via tracks coming in from the north.
