This map area shows the Causeway, which is a century-old land bridge between Singapore and Malaysia. It is a raised roadway and thus separates the Straits of Johor into two, to the east and west of itself.
The Singapore-side Woodlands Immigration Checkpoint is located at the bottom part of the Causeway. The northern side of the Causeway connects to the immigration gateway authorities in the Malaysian city of Johor Bahru. Johor Bahru is in the state of Johor, one of the thirteen states of the Federation of Malaysia.
Not only is the Causeway an important human and goods transportation linkway for cars, lorries, trucks and public buses between Singapore and Malaysia, it also has tracks allowing the running of the railway trains between the two countries. The tracks and trains are operated by Keretapi Tanah Melayu Berhad (KTM), the Malaysian National Railway company.
The Causeway is also important because it carries the pipes in which large volumes of water are pumped from water treatment plants in Johor to Singapore for its consumption.
Seen in the top half and majority of this map is southern part of Johor Bahru city. The Singapore portion occupies a small part at the bottom, with Admiralty Road and Riverside Road.
