Rawalpindi is situated along the historic Grand Trunk Road that connects Peshawar to Islamabad and Lahore. The road is roughly paralleled by the M-1 Motorway between Peshawar and Rawalpindi, while the M-2 Motorway provides an alternate route to Lahore via the Salt Range. The Grand Trunk Road also provides access to the Afghan border via the Khyber Pass, with onwards connections to Kabul and Central Asia via the Salang Pass. The Karakoram Highway provides access between Islamabad and western China, and an alternate route to Central Asia via Kashgar in the Chinese region of Xinjiang.
