The lift on the Hood River/White Salmon Interstate Bridge is currently inoperable.  Port of Hood River Executive Director Kevin Greenwood says the south end of the lift would not raise during a monthly maintenance lift earlier in August.  He says the problem is in a gear box, where cotton to keep moisture out and grease in got caught up on the axle and froze the machinery up.  The unit was disassembled by a firm out of Pasco and it is now being repaired.  Greenwood was unsure of when the repairs will be finished.  He adds the lift if very rarely raised, usually only for tall sailboats a couple of times a year.
