The biggest break in BAMA right now is between Petersburg, Virginia (which itself is a pretty dead city) and Raleigh/Durham, North Carolina along Interstate 85. Five years ago, I would have said it was between Richmond and Fairfax County, Virginia, but the explosive growth of Northern Virginia has negated that, to the point where more than a few people commute from Richmond to NoVA, easily a 2-hour drive in medium traffic.
