Note that the 1961 and 1972 Hopkins County maps clearly show US 67 not with I-30 at Brashear.
TxDOT's on-line map also shows US 67 no banner there (while it does call 67 Business through Sulphur Springs BU67).
There are no minute orders moving US 67 to I-30 there or re-designating it as US 67 Bus, plus there is one discussing speed limits that calls it US 67 with no banner.
