Olympic National Park superintendent Karen Gustin said she hopes work can begin no later than Friday to repair Hurricane Ridge Road.
Three engineers from the Federal Highways Administration and park staff spent Wednesday assessing damage to the Hurricane Ridge Road and developing the preliminary design for repairing the slide area.
The repair design calls for removing the remaining fine-grained fill, replacing it with a rock and gravel foundation, installing a larger culvert and rebuilding the road. Repairs are estimated to take six weeks to complete.
The road has been closed since Monday when a slope below the roadway slid downhill, taking with it most of both travel lanes along a 100-foot long section of road. The damaged site is just below the Heart O’the Hills entrance station, approximately five miles south of Port Angeles.
The road closure applies to all entry, including bicycle, foot, stock and vehicles. The slide area is still active, and soil is continuing to move down slope, undercutting the remaining narrow strip of asphalt and creating a hazard.
