Traffic at the Causeway in 1959 (NST pic)

The Johor-Singapore Causeway was completed in 1923 after four years of construction. It was partially severed in 1942 during the Second World War, to prevent the Japanese army from invading Singapore. However, it was rebuilt once the Japanese had captured Singapore. During the 1964 Race Riots, the causeway was closed from 22 to 26 July, 1964.

The Johor-Singapore Causeway is the first land link between Peninsular Malaysia and Singapore. The second, called the Malaysia-Singapore Second Link, was completed in 1998.
