ISLAMABAD, July 24 (Xinhua) -- The construction of the 392-km Sukkur-Multan Motorway under the China-Pakistan Economic Corridor (CPEC) has been completed after the National Highway Authority (NHA) on Tuesday presented a substantial completion certification to the constructor China State Construction Engineering Corporation (CSCEC).

The motorway, which is known as M5 in Pakistan and the largest transportation infrastructure project under CPEC, is a part of the country's Peshawar-Karachi Motorway and was completed two weeks ahead of contract due date. The M5 was designed for speeds of up to 120 kmh with a total investment around 2.89 billion U.S. dollars.

NHA M5 General Manager Muhammad Naseem Arif said during a ceremony held in Multan that the motorway is very impressive in terms of its quality and construction process, adding that the authority closely worked with the CSCEC and overcame a number of difficulties so that they could complete the great project within three years.

Li Ganchun, chief of the M5 project from the CSCEC, appreciated the security provided by the Pakistani side, saying that the M5 will help Pakistan connect its north and south, improve the country's transportation situation and facilitate social economic development in the region along the motorway.

According to the CSCEC, the M5 project had created some 29,000 jobs for the locals during the construction. The Chinese constructor also built schools, roads, bridges, wells and water channel for the locals to make their lives more convenient.

The motorway is expected to open to traffic in August.
