The Hood River-White Salmon Interstate bridge will be closed to all traffic Sundays through Thursdays from 9:00 p.m. to 5:00 a.m., and on Fridays from 12:00 a.m. to 5:00 a.m. beginning tomorrow through July 7. During the closures, crews will perform repairs to the steel truss members of the bridge, including connection repairs, floorbeam knee brace repairs, rocker bearing modifications, debris removal, joint header repair, and sealing concrete cracks.   Port of Hood River Executive Director Kevin Greenwood acknowledged the closure inconveniences a number of people, but he adds there is no ideal time to get the work done, and it needs to be done in good weather.  On the 4th of July, the closure will end at 5:00 a.m. and will not resume until July 5 at 9:00 p.m.
