Symbol of close relationship between Singapore and Malaya. One time Malaya hinterland to Singapore.

Work on the Singapore-Johore Causeway began in 1919. It was officially opened by the Governor and High Commissioner Sir Laurence Guillemard on 28 June 1924. The Causeway was opened to goods trains on 17 September 1923. Passenger trains began to operate between Singapore and Malaya from 1 October 1923.

The Causeway linked Singapore with Malaya. Rubber, tin, palm oil, and copra were transported to Singapore which right up to the 1960s depended on entrepot trade.

As soon as the retreating British forces had withdrawn into Singapore a 70 foot-wide gap in the Causeway was blown off on 31 January 1942. The Japanese invasion of Singapore began on 8 February 1942 and within a few days the Causeway was repired and it became operational for the invading Japanese troops.

The Causeway today is a symbol of the close relationship between Singapore and Malaysia.
