The Port of Hood River has one more piece of maintenance work it wants to do on the Hood River/White Salmon Interstate Bridge before winter weather settles in.  Last week crews repaired a light fixture on the bridge that had come loose due to vibrations breaking the masthead.  Port of Hood River Executive Director Michael McElwee says other fixtures on the bridge were checked during that repair.  McElwee adds the final task to get done is deck welding that had been planned for late summer but was delayed due to the need to open up the bridge to detoured freeway traffic during the Eagle Creek Fire.  The Port has been undertaking a series of maintenance efforts in recent months to extend the lifespan of the bridge while planning for a new structure begins.
