An excavator is on the site of a rockslide that occurred Tuesday morning on Highway 30 east of Biggs Junction, but there is no estimate on when the Biggs-Rufus Frontage Road will reopen.  Oregon Department of Transportation public information officer Kacey Davey says the goal today is to make room for overhanging rock on the cliff to land so that it won’t go to the railroad below the highway.  She added ODOT plans to start hauling some of the material away, but they have to wait for word from their contractor on when the rock face is stable enough.  ODOT said on Tuesday “boulders the size of cars” had tumbled onto the road.  Officials say to avoid the area.
