The Port of Hood River has maintenance tasks planned for the Hood River-White Salmon Interstate Bridge in the coming weeks.  Port Executive Director Michael McElwee says they will be starting soon a project to replace the skew system in the motors on top of each lift tower, and it should begin in a couple of weeks.  It will require one-lane closures for a period of time in April and May.  A second project that remains out for bid is to handle a variety of maintenance tasks on the bridge.  McElwee hopes that will occur right after the skew system project is done.
