Where would be the best place to get traffic/construction info for the drive to WDW down I-75? Would the DoT website for each state be the best place for updates? The first time we drove to WDW, we got caught in the rockslide detour near Jellico, TN which added 4 hours into our drive time-if we'd have gotten info about it before we hit that area, we might have been able to find a less crowded detour.
