"Holiness Highway" = Interstate 35? Oh, my.

I am considered by most objective observers to be one of those strange beasts called an "Evangelical." I believe the Bible (Old and New Testament) is the inspired Word of God, I believe that Jesus Christ is the Son of God, that He died and was raised to life on the third day, and I enjoy wearing t-shirts with overtly Christian slogans on them. But even I am not sure what to make of the claims that a group of "Evangelicals" believe Interstate 35 is the highway of holiness prophecied in Isaiah 35. Apparently, Pat Robertson did a major piece on it (which is not a recommendation to me, based on our past posts about false prophets).

And a highway will be there;
it will be called the Way of Holiness.
The unclean will not journey on it;
it will be for those who walk in that Way;
wicked fools will not go about on it.
Isaiah 35:8 (NIV)

Even as a man of faith who believes in prophecy, I simply fail to see any connection. Why not one of the many Route 35s around the world? I have to hope that I am missing something. If there is anyone out there from this group who reads Mod-Blog, I'd love to hear from you in the comments section explaining it.
