Road subsidence on Highway 18, two miles west of Grand Ronde, has created a significant road hazard. The eastbound lanes are starting to break up but traffic is being allowed through in the eastbound inside lane.
ODOT crews blame the recent heavy rains that caused local soils to become supersaturated and to slump toward the southeast.
ODOT crews are working at this hour to assess the level of subsidence and to put a big pavement patch over the whole area affected by the subsidence. They said they will have motorists shifted over to the two westbound lanes, with flaggers to regulate the traffic until the patch operation is completed. They say they’re shooting for 5pm or 6pm.
