A big rig left Interstate Five at Bowman Road in Cottonwood early Tuesday morning, but not by way of the offramp. At 3:45AM the semi with double trailers came off the northbound side of the freeway, through the fence and onto Lake California Drive. The driver was uninjured but the truck ended up on its side. Utility poles and a light pole were brought down, blocking the offramp. Cal-Trans is still coordinating the effort to clear the roadway.
