The Port of Hood River says work is on track to reopen the Hood River-White Salmon Interstate Bridge by midnight tonight as planned.  The bridge has been closed since Friday morning to allow for work to replace the bridge lift wire ropes.  The Port says in addition, to take advantage of the four-day closure it scheduled additional bridge deck maintenance welding that has continued all weekend and into today.  That’s to make significant and needed weld repairs to the steel grate bridge deck.  The Port says several other small repair projects and bridge inspections were also taking place, adding all crews are on schedule to reopen the bridge at midnight tonight.
