UPDATE 1:55pm, 12/11/17 -- Highway 20 between Willits and Fort Bragg has been reopened, though there may be some delays, and it's unclear if the road is fully opened, or if it's a one way traffic control situation.
We'll continue to update.
Here's the update from CalTrans District 1's Facebook page:
MENDOCINO Co., 12/11/17 -- A big rig overturned on Highway 20 this morning, scattering scrap metal across both lanes of traffic, about three miles east of Highway 1, and leading to the closure of the road. The accident occurred near the Wildwood Campground and the California Highway Patrol reports that clean up could take between three and four hours. The driver was in the vehicle and an ambulance was dispatched, but an early call for a medical helicopter was later canceled. The condition of the driver remains unclear.
