Malaysian State Roads system
From Wikipedia, the free encyclopedia
The Malaysian state roads system (Malay: Sistem Laluan Negeri Malaysia; Chinese: 马来西亚州级公路系统) is made up of the secondary roads in Malaysia, with a total length of 264,906.73 km (as of December 2023).[1] The construction and maintenance works of state roads in Malaysia is managed by Malaysian Public Works Department (JKR) of each state and funded by state governments. The standard of the state roads is similar to the federal roads except for the coding system, where the codes for state roads begin with state codes followed by route number, for example Johor State Route J32 is labeled as J32. If a state road crosses the state border, the state code will change, for example route B20 in Salak Tinggi, Selangor will change to N20 after crossing the border of Negeri Sembilan to Nilai (Both B20 and N20 now become Malaysia Federal Route 32).
