The world's highest motorable pass?

Khardung La is widely, but incorrectly, believed to be the highest vehicle-accessible pass in the world. A well-graded Indian military road (visible on 2011 imagery on visual globe systems such as Google Earth) reaches 5,610 metres (18,406 ft) 250 meters west of the 5,545 metres (18,192 ft) Mana Pass on the India - Tibet border. It connects with an equally well-constructed, slightly lower Chinese military road based on SRTM data at posting intervals of 30 meters. There are also higher motorable passes at Suge La, west of Lhasa, 5,430 m (17,815 feet), and Semo La 5,565 m (18,258 feet), between Raka and Coqen in Central Tibet. Both these elevations are supported by GPS and SRTM evidence and the latter was also measured by the Catalans and supported by the Cartographic Institute of Catalonia. Vehicles have been driven over the 5,582 metres (18,314 ft) Marsimik La, in the Indian Karakoram to the north-east of Khardung La, but it is debatable whether this pass should be considered to be motorable.
