To be honest I did read the first few paragraphs and then went looking for info about the Dallas High Five as I don't think I've even been on anything taller than ~three levels— the major highway near me is the 401 and I believe it is mostly cloverleafs other than the junction with 410 and 403, so I'm much more used to that arrangement.
