Multiple crashes on Interstate 5 Thursday afternoon between Woodland and La Center had the highway backed up for miles. Trooper Will Finn, a Washington State Patrol spokesman, said one J.L. Storedahl & Sons tractor-trailer rear-ended another on Interstate 5 between La Center and Woodland around 4:30 p.m. The crash also spilled sand from one of the trailers onto the road, blocking the highway, Finn said. One of the drivers had minor injuries, he said. Then things got worse. “During this incident, we had an additional three-vehicle crash that occurred in the backup, and then another two-vehicle crash that occurred in the backup,” Finn said. No one was hurt in those crashes, Finn said, but the resulting investigation and clean-up had the roadway backed up for nearly to 4 miles. Finn said all lanes were clear by about 6:15 p.m., but it would take time for traffic to clear. “We’re three lanes deep and barely moving,” he said.
