UPDATE: Road Cleared.
According to the CHP site, an accident occurred at around 8:40 this evening near Airport Rd. north of McKinleyville. A 4 door Taurus is involved. There are 4 people trapped with multiple injuries. The Humboldt Co. Sheriff’s Office (I believe, the notation used is HSO) is closing down the southbound onramp.
I will update as information comes in.
