heres another graphic-not next pic I promised yet-to show where KMG pic I post next was taken from -although as per map convention mine is also W of hwy here,still the orientation is different than graphic just posted -here big river (wadi) on right is N-S more than E-W and hwy has a W-E slant rather thanN-S slant in apparently the same area- and i'm aware the River changes from  an E-W primary direction to a N-S primary direction after passing CWRN
