The D-O-T hopes to reopen the Mason Street Bridge by the end of the month. Engineers have determined that rusted bolts broke inside gear bearings in one of the four corners of the lift bridge July 6th–causing the gears to lock up with the spans in the up position. D-O-T Regional Maintenance Supervisor Scott Nelson says it’s an issue they don’t see very often. Ultrasound scans on the other three corners of the bridge found similar bolt rusting–so those will also have to be replaced before the bridge can return to operation. The expected cost of the repairs is half a million dollars.
