Seriously though, after some research, I do believe Awaywego is partially correct. Here is a link to a photo of the entrance to the bridge from the Falmouth side:

When you look at the bridge in Google Street View, it looks exactly the same. This is the bridge that crosses the Licking River when you are leaving town and is known as the Shoemaker Town Bridge. However, on June 12 of this year the weight limit was raised according to the Falmouth newspaper. Without a subscription though, it does not tell what it was raised to. As John said the best thing to do is to contact the district Highway Engineers Office.
On edit: seems like even I was looking at the wrong bridge after seeing Charlie's post, but the info may still be applicable if you are coming in from Falmouth??
