The Port of Hood River Commission has approved a contract with HDR Engineering in Portland to handle evaluations of the lift span on the Hood River Interstate Bridge.  Port Executive Director Michael McElwee said a March inspection by long-time bridge consultant HNTB found the need for further evaluations of the lift span setting with a more specific and pro-active maintenance program that HDR specializes in.  HDR will do further inspections and measurements for engineering tasks at the end of October and early November, and they will prepare their recommendations on the lift span settings with repairs to be done this coming spring.
