GREEN BAY, Wis. (AP) – A trucker was crossing the Leo Frigo Memorial Bridge in Green Bay early last Wednesday when he felt something strange underneath his rig – so strange that he reached for his cellphone and dialed 911.  Press-Gazette Media reports (http://gbpg.net/16Cc8Oh ) that when he reported the pavement on the bridge seemed to be sagging, the dispatcher either could not understand him or could not believe it.  After being dispatched to investigate, a Green Bay police officer reported about 10 minutes later that nothing appeared unusual. It would be almost another hour before officers realized the 120-foot-tall bridge had, in fact, sagged and that the highway had to be shut down.  The bridge remains closed indefinitely while officials try to determine why a support pier sank, causing a 2-foot dip in the pavement.
