New Pantai Expressway, is a major expressway in the Klang Valley region of Malaysia. The 19.6 KM expressway has provided an easier access to Kuala Lumpur from Subang Jaya and Bandar Sunway to avoid the traffic jams on the Federal Highway Route 2 during rush hour. It comprises the Main Link and the Salak Link. The highway start is located at Jengka Interchange in Subang Jaya, Selangor.
The expressway was known as Jalan Subang Utama (Persiaran Tujuan–PJS), Jalan Klang Lama 2 (Federal Highway–Jalan Templer side) and Jalan Pantai Dalam (Jalan Bangsar–Kampung Pantai Dalam). The project was awarded to Maxtro Engineering Sdn Bhd, a subsidiary of Berjaya Group but it was handed over to the new concessionaire, New Pantai Expressway Sdn Bhd, a subsidiary of IJM Corporation Berhad in 2002.
It was constructed between 2000 and 2004. Construction of the expressways was led by Road Builder (M) Holdings Berhad (RBH) which in 2007 was acquired by IJM Corporation Berhad. Phase 1, which is between Jengka roundabout and Bandar Sunway was completed in 2002. The next sections from Bandar Sunway to Pantai Baharu (Phase 2) and Pantai to Salak South (Phase 3: Salak Link) were completed in 2003. During construction, the concessionaire temporarily relocated 2,000 squatters in Pantai Dalam while building them 980 low-cost apartments close to their settlement.
The expressway was officially opened on 30 April 2004. Tujuan Interchange which replaced a T-junction was constructed between 2004 and 2006. The Bulatan Gasing ramp from NPE to Jalan Gasing was also constructed between 2004 and 2006. A special ramp to Sunway Pyramid's parking floor was constructed between January and November 2007. It was opened in December 2007.
On 13 February 2009, the PJS 2 toll plaza for Kuala Lumpur-bound was abolished. This was at the request of the government following complaints from nearby residents who had no alternative route in a Kuala Lumpur-bound direction and were thus compelled to pay too frequently.
