Which highway are you taking into Memphis ? I am assuming either US 78(Tupelo) or US 72 (Corinth), but don't know.
Two major construction projects currently, east Memphis as I-40/240 junction, 3-4 year project (2 additional levels of flyover, and bridge replacement). This one shouldn't affect you UNLESS you are coming into Memphis on I-40, or possibly US 64.
West Memphis is site of major payment rebuild in a 4-5 mile segment that I-40/I-55 share. Single lane each direction. Travel can back up a couple of miles at times, most of the time it moves well, about 40-45 mph. Approx I-40 mile markers (including lane closures before and after) are mm 281 on the east end and mm 274 on the west end.
If you enter Memphis on 72 or 78, follow the 240 loop around the south side of town, cross the Miss River on the I-55 bridge. Check local am radio traffic report (watch for sign, maybe 1600-1700 am). If traffic backs up, one option is to take US 70/79 thru West Memphis (Broadway). It is all 4 lane, maybe 5-6 traffic lights. Pick up I-40 at exit 271 (AR Hwy 147).
Have a good trip.
