Timber Road was closed indefinitely between Strassel and Cochran roads after we detected that a slow-moving landslide near the S curves was increasing in activity. Movement, including substantial pavement settlement, created potential for significant damage should the landslide movement continue to intensify.
Local access is allowed outside of the landslide site. Timber Road is closed to all traffic at the landslide site. A long-term road closure plan is in place, including permanent barriers around the landslide site.
We will complete a geotechnical evaluation to find a long-term stabilization solution before the road re-opens. We cannot currently estimate when re-opening will be possible.
We expect the geotechnical evaluation to be complete in September 2023 and will evaluate repair options once it is done.
