Unused Dexter Press card 84134 from Sanborn Souvenir, with rounded corners and a caption on the back calling the Suspension Bridge you see here spanning the Arkansas River the “World’s Highest Bridge”.  It should surprise nobody that Googling a list of “world’s highest bridges” now ranks this one as #24, behind one in Mexico, one in Papua New Guinea, and 21 in PR China.  Grade: 1
