Work on strenghtening the piers of the Milton-Madison bridge and erecting the towers for temporary piers to support the new bridge superstructure has been halted by high river levels. The river has submerged the cofferdams placed around the piers which had allowed workers access to the piers down to the riverbed. Water was constantly being pumped out of the workspace allowing for rebar placement and pouring of concrete. The river has made the work ramp on the Madison shore inaccessible. The trestle on the Kentucky shore was barely above water Tuesday morning. The Ohio River level is projected to raise another two feet by Friday.
