The China Gulch culvert under Highway 1 at the intersection of Old State Highway in Gualala is failing, causing a sinkhole to form at the intersection, and so it needs to be replaced promptly. CalTrans has approved $9.9M for emergency repair, and hopes to complete repairs by the end of November, 2025.
