Dude, I can’t remember back that far. I used to drive my motorcycle from Mesquite to my job as a security guard at NAS Dallas and do not remember the exits anymore.
A waste is a terrible thing to mind!
It was a long time ago. But, even after they removed the toll booths, those ramps remained.
You can still see them on google maps:

Look for the loops under the label for the Crowne Plaza Suites.
The toll booth used to be on the access road southeast of where the highways intersect.
