REDFIELD, S.D. (AP) – A collision involving three semitrailers blocked traffic for about three hours near Redfield. The Highway Patrol says a semi hauling a 131-foot-long wind turbine blade collided with another semi and sent that truck crashing into a third at the intersection of U.S. Highways 281 and 212 about midday Wednesday. Trooper Brian Korbel says that all three trucks had significant damage, and one driver was taken to a hospital as a precaution. The wind turbine blade was on its way from an Aberdeen company to a wind farm being built in Kansas. Damage to the blade was not immediately known.
