(Port Orford, OR) -- Drivers may be able to use Highway 101 south of Port Orford by Friday afternoon. Early Monday morning, a landslide that runs under the highway sank about 12 feet. Crews have been working to repair the damage. If the weather cooperates, they hope to open one lane through the area. If there's too much rain, it might delay the reopening. If the slide continues to move, they'll have to close the highway again.
