What about the Wal-Mart proposed for Exit 14?

Here in Abingdon, periodically there is talk about a new Wal-Mart to be built off Jonesboro Road at Exit 14. Exit 14, must be one of the worst-designed and therefore most dangerous interchanges of Interstate 81 in Virginia. Supposedly, a necessary precondition for the opening of the Wal-Mart is the reconfiguration of the exit with private funds, which in itself might be a good bargain for the public.

This topic came to mind as I read Is Wal-Mart good for America? by Bruce Bartlett.
