The M-2 Motorway or the Lahore–Islamabad Motorway is a north–south motorway in Pakistan, connecting Rawalpindi/Islamabad to Lahore, and is the first motorway to have been built in South Asia. The M-2 is 375 km long and located entirely in Punjab. It continues on to eventually become the M-1 motorway, connecting Islamabad and Peshawar. The M-2 crosses the junction of M-4 at Pindi Bhattian and M-3 at Dera Saithan Wala. The motorway is also a part of the Asian Highway AH1. The motorway was constructed during Prime Minister Nawaz Sharif's rule and cost over Rs. 60 billion and was opened in November 1997. One of the most expensive motorways in Asia, it also has one of the highest pillared-bridges in Asia at the Khewra Salt Range section.
