The purposed to built the bypass to Port Klang began in 1970s. Construction began in 1972 and completed in 1975. Today this highway are maintained by the Lebuhraya Shapadu Sdn Bhd (a member of Shapadu Corporation Sdn Bhd) and Malaysian Public Works Department (JKR).
The bypass is not considered safe because of many accidents involving heavy vehicles along this road, especially the area around a school. On 16 May 2005, on Teacher's Day, a school girl from Sekolah Kebangsaan Rantau Panjang was knocked by a lorry while she was crossing this road.
