The Kuala Lumpur–Seremban Expressway is a main expressway in Kuala Lumpur, Malaysia. This expressway links Kuala Lumpur in the north to Seremban, Negeri Sembilan in the south. Some maps label this highway as E2 as it links directly with the North–South Expressway Southern Route; however this appellation is not strictly correct as this particular stretch of road is not managed by PLUS Malaysia Berhad, but rather by ANIH Berhad (formerly known as Metramac Corporation (MetaCorp)). Consequently, the toll rate at Sungai Besi Toll Plaza had included an extra payment to cover the Kuala Lumpur–Seremban Expressway until 2018, when the toll was abolished. In 2007, the expressway was assigned its own route number of E37 together with Salak Expressway. Route background The Kilometre Zero of the expressway starts at the Razak Mansion Interchange while its southern terminus is right before the Sungai Besi toll plaza at the North–South Expressway Southern Route E2. Its final kilometre (KM8.1) is also the final kilometre of the North–South Expressway E2 (KM310.8). History The construction of the 63.4 km (39.3 mi) controlled-access expressway from Kuala Lumpur to Seremban began on 27 March 1974 as one of the Second Malaysia Plan (RMK-2) project, with the total cost of RM32.9 million. It consists of 14 interchanges, 2 laybys and 6 toll plaza (Sungai Besi, UPM, Kajang, Bangi, Nilai and Seremban). Funded by a loan by the World Bank, the expressway was constructed in three phases; the first phase was from Kuala Lumpur to Nilai, while the second phase was from Nilai to Seremban. The third phase was the rehabilitation of the old Federal Route 1 from Kuala Lumpur to Seremban as a toll-free alternative to motorists. The expressway was opened to motorists on 16 June 1982, where the Minister of Works at that time, Datuk Seri S. Samy Vellu himself became the first motorist to pay the toll of the expressway. The Kuala Lumpur–Seremban Expressway was the first expressway in Malaysia to implement the closed-toll system in Malaysia. The RM32.9 million expressway became a pioneer route for the North–South Expressway Southern Route. Initially, the expressway ended at Jalan Seremban–Tampin intersection in Senawang before being extended southwards as part of the North–South Expressway; Exit 220 Senawang Interchange was constructed to divert the expressway through traffic to Ayer Keroh. After the extension of the expressway to Ayer Keroh was completed in 1986, the old Seremban toll plaza at Labu was
