The Hood River-White Salmon Interstate Bridge will be closed from midnight to 5 a.m. on Friday to do work on a structural support on the bridge’s lift span.  It’s the first of a few bridge closures that are upcoming this year.  Port of Hood River Deputy Executive Director Genevieve Scholl says this spring asphalt replacement will need to be done on both approach ramps, and could require three to four full days of closure.  The project will go out for bid in a couple of weeks.  Then in the fall, replacement of the wire cables that raise and lower the lift span will be done.  Scholl says they don’t know what kind of closures will be required when that work takes place.
