 At that time, SH 118 south of Alpine departed from its present route near Adobe Walls Mountain to Terlingua rather than going directly to Study Butte as it does today.From Terlingua, SH 118 then proceeded eastward through Study Butte to SH 227.In 1941, the designation of SH 118 along the road between Alpine and Terlingua was canceled and returned to county maintenance.
