(Portland, OR)  --  The Morrison Bridge is set to close in April for extensive repairs.  Multnomah County has approved funding for the project after arriving at about three-million-dollars in settlements with companies that officials say are responsible for defective material used in bridge refurbishing five years ago.  County leaders tell KOIN-TV the structure remains safe, as repairs have been made lane by lane.  The bridge will be closed for a day on November 6th for further repairs and inspection.
