Bukhara – Khiva - Nukus: It is a 460km to Khiva from Bukhara and a further 200km onto Nukus. The first 70km is slow however after that there is a new road all the way to Turtkul followed by more slow conditions onto Urgench and Khiva. The road however is being upgraded over last year or so, and so now I expected it to be better. Sand drifts in desert sector always an issue. Can do around 60Km/hr on average most of the way.
(ED: Any comments on current road conditions or other relevant information welcome below).
