An Abandoned Bridge in Logan County

This little Warren Pony Truss Bridge is located off Township Road 26 in Logan County. It looks like it has been abandoned for some time as the decking is completely gone and there is a lot of overgrowth.

Look closely through the plant growth and you can see a standard "Weight Limit" sign for this bridge. The photo below gives a better view.

You've Got To Be Kidding!

The Ohio DOT weight limit sign looks fairly new! I'm guessing the workers got quite a kick out of putting this one up. However the bridge is officially listed as "in service" as of 2005 so it must have a sign. I wonder how they came up with the limits?
