The 19.6-kilometre (12.2-mile) expressway runs parallel to the Federal Highway, between Subang Jaya, Selangor in the southwest and Bangsar, Kuala Lumpur in the northeast.

During construction, the concessionaire temporarily relocated 2,000 squatters in Pantai Dalam while building them 980 low-cost apartments close to their settlement.

About 50 people in Petaling Jaya Selatan staged a peaceful rally at the New Pantai Expressway’s (NPE) Kampung Dato' Harun toll plaza near Taman Medan here, demanding the NPE toll be abolished as it was burdening the people, especially nearby residents.

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.

The government agreed to abolish the toll plaza from Sunway Pyramid heading towards Kuala Lumpur beginning 00.01 hours 14 February 2009.
