Congratulations on your promotion!
I drive by Springhill Mall every morning on my way to work (Springhill Ford on Rt. 25) and it seems like most of the traffic in that general area is all going east. 72 backs up a lot going eastbound but not westbound, so you'll be fine because of coming from the city. Give yourself plenty of time to get there for a few days to figure out how long it takes every day. Watch out for police on 72 though, they have plenty of hiding spots in that area.
