FOUNTAIN — Two separate crashes just half an hour apart caused major traffic delays on southbound I-25 just south of Colorado Springs early Thursday afternoon. The first accident involved a camper trailer that flipped over and collided with one other vehicle at mile marker 130. Thirty minutes later another vehicle hauling a trailer caused a chain reaction crash involving a SUV and a Honda CRV at mile maker 132. Fortunately, no one was hurt in either accident.
