As I have stated, Rt 66 is a 'Bear' on Fridays going in and a bigger one on Sundays going out...this won't change and only get worse.
They're working on the bridge at Rt66 and 441/411 (Chapman Hwy ..the nasty intersection in Sevierville at the courthouse, Walgreens etc) and will cause major delays.
Currently, they are repairing potholes on the 'spur' between PF and GB and is reduced to a single lane.
Bottom line: if you're coming in on a Friday, stay clear of Exit 407 (Rt66) big time headache!
They're working hard on a new major 'by-pass' and should be done for 2007. New exit off I-40, by-passing Sevierville and giving you options for PF or GB. Major improvement!
The traffic issues are mostly Friday, Sat & Sunday..the weekdays are always busy, but no major back-ups. There are many options to avoid these. Any Chamber location has free Sevier County maps and they will be of great help...make sure it's a Chamber and not just a 'Welcome Center', as those are really 'Time Share' offices that will p--- you off and may dampen your retreat.
