If you are talking about the bridge over the Yazoo than yes coming out of the flat delta that hill looks large but I can assure you that it is not bad you can make it easy. That road to the port is Business 61 and it will take you through industrial areas and then right through downtown Vicksburg, not something I would want to do it an RV. Bus. 61 is definitely not a bypass.
