Federal Highway (, , abbreviation: FH2) is a Malaysian controlled-access highway connecting the capital city of Kuala Lumpur, and Klang, Selangor. The highway starts from Seputeh in Kuala Lumpur to Klang, Selangor. It is the busiest highway in Klang Valley during rush hour from/to Kuala Lumpur. The Federal Highway is coded as Federal Route 2. History The history of the highway started after the separation of Singapore from Malaysia on 9 August 1965, when the Malaysian government decided to make Port Swettenham (now Port Klang) as Malaysia's new national port as a replacement of Singapore. As a result, the government planned to build a highway connecting Port Klang to Kuala Lumpur by upgrading the former Kuala Lumpur–Klang Highway (Jalan Kuala Lumpur–Klang) (opened to traffic on 14 January 1959) to a full motorway by replacing the existing at-grade intersections with interchanges, making the Federal Highway as Malaysia's first expressway. The Kuala Lumpur–Petaling Jaya Traffic Dispersal Scheme was implemented in 1974 under the surviliance of the Malaysian Public Works Department (JKR). This scheme includes the Kuala Lumpur Inner Ring Road, Kuala Lumpur Middle Ring Road 1, Jalan Syed Putra and Federal Highway Route 2 (Kuala Lumpur–Petaling Jaya). Funded by a loan granted by the World Bank, the upgrade works for the Federal Highway from Subang Airport Interchange to Kuala Lumpur started from 1974 until 1977. The highway was originally a 4-lane limited access highway except for the Petaling Jaya stretch where it became 6-lane highway. However, in 1992 PLUS Expressways, the concession holder of North–South Expressway has upgraded the entire highway to a 6-lane highway with two toll plazas, Batu Tiga and Sungai Rasau. The 6-lane toll highway had begun in operation on 11 May 1993. The highway handles incredible volumes of traffic there is significant congestion at more or less any time of day. Upgrading of the Subang Airport Interchange and the Majlis Link The upgrading of the Subang Airport Interchange including main link of Subang–Kelana Jaya Link from Sultan Abdul Aziz Shah Airport Highway (route 15) of Federal Highway (route 2) to Persiaran Kewajipan near Menara Mesiniaga began at the end of 2005 and the construction of the new Majlis Link in September 2005. Both project are led by Malaysian Public Works Department (JKR). While the main contractor are the Ahmad Zaki Resources Berhad (AZRB) and Ho Hup Construction Company Berhad (HHCC). The Majlis Link was completed in March 2007
