1974, Steven Jerome Bryant, College algebra and trigonometry, page 388:

A fourth route, of no practical logistical import, is the Sinkiang-Tibet highway route. This route extends from Kashgar (K'o-shih) in Sinkiang to Gartok in extreme western Tibet. This portion of the road is considered to be fair weather with the exact width unknown. From Gartok two routes of limited motorability extend to Zhikatse and Nagchhu Dzong (Hei-ho). The route from Gartok to Nagchhu Dzong, a point on the Lan-chou to Lhasa route, is thought to be little more than a course marked across the plateau and of no logistical value. Although motor vehicles have been operated between Gartok and Zhikatse, this route is of questionable motorability and of no logistical value.
