Motorways of Pakistan
Motorways of Pakistan () are a network of multiple-lane, high-speed, controlled-access highways, which are owned, maintained, and operated federally by Pakistan's National Highway Authority. At present, 2816 km of motorways are operational, while an additional 1213  km are under construction or planned. Motorways are a part of Pakistan's “National Trade Corridor Project” and “China-Pakistan Belt Road Initiative,” from Khunjerab Pass near the Chinese border to Gwadar in Balochistan. All motorways in Pakistan are prefixed with the letter 'M' (for "Motorway") followed by the unique numerical designation of the specific highway (with a  hyphen in the middle), e.g. "M-1". History. Pakistan's motorways are an important part of Pakistan's "National Trade Corridor Project", which aims to link Pakistan's three Arabian Sea ports (Karachi Port, Port Bin Qasim and Gwadar Port) to the rest of the country through its national highways and motorways network and further north with Afghanistan, Central Asia and China. The project was planned in 1990. The China Pakistan Economic Corridor project aims to link Gwadar Port and Kashgar (China) using Pakistani motorways, national highways, and expressways. Patrolling and enforcement. Pakistan's Motorways are patrolled by Pakistan's National  Highways & Motorway Police (NH&MP), which is responsible for enforcement of traffic and safety laws, security and recovery on the Pakistan Motorway network. The NH&MP use SUVs, cars and heavy motorbikes for patrolling purposes and uses speed cameras for enforcing speed limits. Emergency runways. The M-1 motorway (Peshawar-Islamabad) and the M-2 motorway (Islamabad-Lahore) each include two emergency runway sections of length. The four emergency runway sections become operational by removing removable concrete medians using forklifts. The Pakistan Air Force (PAF) has used the M-2 motorway as a runway on two occasions: the first time in 2000 when it landed  an F-7P fighter, a Super Mushak trainer and a C-130 and, again, in 2010. On the last occasion, the PAF used a runway section on the M-2 motorway on 2 April 2010 to land, refuel and take-off two jet fighters, a Mirage III and an F-7P, during its Highmark 2010 exercise.
