A Vicksburg Warren School District school bus passes in front of an 18-wheeler that clipped a low-hanging telephone line at Baldwin Ferry and Mission 66 at 6:35 this morning, causing backups of car and bus traffic headed to Vicksburg and Warren Central junior high schools. Vicksburg police Sgt. Jackie Johnson said the driver, Zeric Thompson, 41, 5837 Old Canton Road, Jackson, was northbound on Mission 66 just before daylight and did not notice the hanging line until his trailer caught it and pulled it down. No injuries were reported.
