The North-South Expressway Central Link (NSECL) is a critical link for the NSE providing northbound and southbound travelers with an uninterrupted journey bypassing the city congestion in Kuala Lumpur. The 63-kilometre expressway connects the NKVE (at Shah Alam) to the NSE (at Nilai North Interchange) and a popular route for travelers heading to the Kuala Lumpur International Airport (KLIA) and the Sepang F1 Circuit.
