In 1990, the government put up a proposal to build a 16-kilometre Woodlands MRT line at a cost of $1.3 billion. It would connect Choa Chu Kang and Yishun MRT stations on the North-South Line and would comprise six MRT stations: Yew Tee, Kranji, Marsiling, Woodlands, Admiralty and Sembawang. In February 1991, the government went ahead with its plan to construct the Woodlands Extension. By 10 February 1996, the Extension was completed and opened by Prime Minister Goh Chok Tong. The connection brought a much-awaited convenience to some 130,000 Singaporeans living in the north. It also supported the Urban Redevelopment Authority's plan to develop Woodlands into the northern hub of Singapore.
