It is pretty rough but they've been doing work on it for last several years. They are actually digging up concrete for the whole right lane and repouring.
My daughter just finished 4 years of college at Georgia Southern near Savannah and now my son is there. Daughter was in marching band first 2 years. Between weekend stays for visits, orientations, football games, etc. plus trips to Savannah and Hilton Head, I've probably taken MH and previous 5'er down I16 30+ trips. Right now big issue is the closing of 1 lane for construction for several miles can cause traffic build-up.
I've personally not had any issues.
