I prefer to call it the Crossroads of America because it is the only point in the country where two cross-national freeways meet (besides MSP, which isn't the same since I-35 actually splits). I-40 (Cal to N Carolina) and I-35 (Texas to Minnesota; really Mexico to Canada) meet at this crossroads; along with spur I-235.

There's no other crossroads like this in the nation.
