Narrative:

Slc tower cleared small aircraft for takeoff on 16L with a left turn to unknown heading. At the same time slc tower cleared us for takeoff on 16R. As we were rotating I saw that the small aircraft had made a right turn instead of a left turn. I pointed the traffic out to captain, who then made a 15-20 degree right bank and pulled the nose up to avoid a collision. The tower was notified. They did not see the occurrence. Company dispatch was notified and the proper documents filed.
