Is metal detecting allowed in this area?

This bridge is on a section of the pre-four lane National Road before 1940. It was preserved as "Historic U.S. 40" as at least one sign on modern U.S. 40 indicates. The bridge deck is concrete with bad cracks which allow water to leak which collects between the arches and which is draining through the mid-stream pier. This is destroying the pier which will be the end of the bridge.

Yikes, what happened to that railing? It wasn't so torn up when I visited last in 2009.
