U.S. 75
	Where US 75 ends in Dallas, I-45 begins, and vice versa.  So it only makes sense that US 75 be extended southward to Houston and beyond. US 75 would continue down the I-45 corridor and absorb all sections of TX 75.  In addition, the rest of the Central Expressway in Dallas that is currently signed as TX 310 would be redesignated as US 75 and provide a legitimate connection to US 175. In Houston, US 75 would break off I-45 at US 59 (Future I-69) and take over TX 288 all the way down to Freeport, where it would end.
