GREEN BAY, Wis. (AP) -- State Department of Transportation officials are working through the weekend to figure out why a Green Bay bridge sank two feet.
Officials closed the Leo Frigo Bridge Wednesday after a support pier unexpectedly sank two feet, causing a deep dip in the pavement.
DOT spokesman Kim Rudat says workers were checking for movement in other support piers and testing the area soil Saturday. That will tell them if they need to shore up the bridge before doing other work.
He says they haven't found any movement yet but they've attached equipment similar to seismographs that will sound alarms if there is.
On Friday, Governor Scott Walker declared the closure of the bridge a disaster. It could lead to federal reimbursement for the first 180 days of repair work.
