Traffic is much worse going south to Little Rock after the game then north to Bentonville. The Bentonville-Fayetteville route is only 20 miles and is very easy travel. If I-540 gets too cramped for your liking, there are two N/S bypasses you can take to Bentonville, which are AR 112 and US 71B. It's not a bad trip at all. I do warn you though, the football team stays in Bentonville on Friday night, so be aware of when you travel that, for the 3 hr. window before the game, that you'll see a full police escort and sirens everywhere leading the Razorbacks down I-540.
