There will be intermittent, single lane closures of the Hood River/White Salmon Interstate Bridge Tuesday and Wednesday.  The closures will take place between the hours of 9:00 a.m. and 2:00 p.m.  Port crews will be performing maintenance welding to the bridge deck.  Flaggers will direct traffic on the bridge.  Bridge users should plan for up to 20 minute delays during these hours on both days.
