Port of Hood River Commissioners received an update on the investigation into the damage caused by the apparent striking of the lift span pier on the Hood River-White Salmon Bridge sometime in early October.  Port Executive Director Michael McElwee says engineers are currently analyzing data from inspections last week to determine if the lift towers are out of alignment.  Next week climbers will do hands-on inspections of the lift span and tower steel.  Investigators believe the impact likely happened at night between September 30 and October 11, and anyone who may have felt a shake on the bridge or saw something unusual on the water during that time period is asked to call the Port of Hood River.
