[quote name='monkeylizard' timestamp='1353169334' post='847197']840 wasn't really intended to be used from end-to-end (Dickson to Lebanon or vice-versa). It's longer in both time and distance. If you're passing through at rush hour you can avoid downtown with I-440 or Briley Parkway. 840 was meant to divert traffic entering Nashville and changing direction. Such as up from Alabama and then east to Knoxville. The long term plans are to create a northern loop that will connect from Lebanon up through Trousdale Co., Springfield, Clarksville, and back down to Dickson, but that may never happen due to having to build 2 very expensive bridges over the Cumberland.[/quote]
When was the last time you were on 440 during rush hour? That's the most congested stretch of roadway during rush hour. I avoid 440 from 6:30 am - 9:30 am and 3:00 pm - 6:30 pm.
