One more post, this time germaine to the I-22 topic. I last drove the section of US 78 between Birmingham and Memphis in 1998. At that time, the entire freeway was complete in Mississippi, but most of the roadway had the infamous gravel shoulders, except for the last sections completed, where the shoulders were paved from the start.
Have any sections of US 78 in Mississippi had their shoulders paved or other improvements made to the roadway to bring them up to interstate standards since 1998? Once I-22 is complete and signed in Alabama, will I-22 be signed as I-22 immediately in Mississippi, or will we still be dealing with "Future" signs, etc for years to come in that state?
