Welcome to DallasHighFive.org.
The Dallas High Five is a multiple hundred thousand dollar project involving the crossing of 5 major highways in the Dallas, TX area.
The project was undertaken in 2002 and took about three years to complete.
The image above this text shows what the completed project looks like now. As you can see it appears to be quite the maze.
More public information about the details, costs, and current status of this project can be found on the Wikipedia page titled High Five Interchange.
