The travel problems just keep mounting for people traveling in and around Atlanta. A portion of I-20 in southeast Atlanta buckled this morning, leaving a huge bump on the pavement. Officials are blaming the buckle on an underground gas leak. Witnesses say the bump in the road was up to three feet high. Crews had to shut down the road to complete repairs. This incident comes just hours after the downtown connection through the heart of Atlanta was shut down due to a tractor-trailer chemical spill. This accident happened near the partial collapse of a bridge on I-85 last month.
