The DNT ended at LBJ Frwy last time I was on it!
I have fond Memories of the Dallas area I grew up in and that is how it will stay in my thoughts. Not likely to ever go back there, the last time I was in the area was around 1997 for a funeral and now none of my kinfolk live in Dallas.
The DNT now ends at US 380 in Prosper. Great fun to make a high speed run down the entire length of it on a motorcycle at, er, “some” miles per hour. :D
The urban area of the Metroplex has gotten a lot larger in the last 10 years alone.
