Interstate 90 in Lake County reopened all lanes early Friday morning in Lake County, more than 12 hours after a Thursday afternoon crash involving nearly 50 vehicles created havoc on the highway and seriously injured at least three people. Reports vary on the exact number of people injured in the crash, which occurred at about 2:45 p.m. when a semi-truck jackknifed while heading east between Ohio 44 and Vrooman Road, setting off a chain-reaction involving several vehicles. Witnesses said there were heavy flurries at the time and road conditions were slick when the truck jackknifed, said Lt. Charles Gullett, post commander for the State Highway Patrol in Chardon.
