Gwinnett County Public Schools will delay school opening two hours on Tuesday, December 11, due to the possibility of icy road conditions. Morning buses will run two hours later than the regularly scheduled pick-up time. This means if your bus usually comes at 6:30 a.m. it will be at the stop at 8:30 a.m. tomorrow. All schools will end and release at their normally scheduled time. All afterschool and evening activities on Tuesday will be held as scheduled.
