Customs & Immigration Quarantine Complex
The Southern Integrated Gateway (Malay: Gerbang Selatan Bersepadu) refers to a complex in Johor Bahru, Malaysia incorporating the city’s main railway station, JB Sentral, and a customs, immigration, and quarantine complex (CIQ), the Sultan Iskandar Customs, Immigration and Quarantine Complex or Sultan Iskandar Complex (Malay: Kompleks Kastam, Imigresen dan Kuarantin Sultan Iskandar), named after Sultan Iskandar of Johor. The station and complex are the main transportation hub of Johor Bahru and southern Peninsular Malaysia. The Malaysian Public Works Department was responsible for the design and construction of the project; Gerbang Perdana Sdn Bhd was the main contractor. This project is part of the Iskandar Malaysia development corridor project. The CIQ complex was opened to vehicular traffic on 16 December 2008. As of October 2010, the JB Sentral railway station entered operation and service to the old Johor Bahru railway station ceased.
