In the planning stages of the NEL, it was confirmed by then-Communications Minister
Mah Bow Tan in 1995 that the line will pass through the Potong Pasir constituency, then an opposition ward. However, he added that the line would not stop in the constituency as it would not be economically viable. Citing a feasibility study by consultants for the line, he explained that without a station in Potong Pasir, it will reduce costs for the NEL by about S$1 million (US$ million) annually. This was refuted by then Potong Pasir
Member of Parliament (MP)
Chiam See Tong, who said it would become a "strong station" once there are developments around it. When the 16 NEL stations were revealed in March 1996, Potong Pasir station was announced as "Sennett" and it was only to be built when its surroundings have been "developed intensely". The residents of Potong Pasir "took in their stride" upon learning of the station's status and alleged that this was due to its location in an opposition constituency. There were claims that the station (along with Woodleigh, another station in Potong Pasir) would only be opened if a
People's Action Party (PAP) candidate managed to secure the constituency. In the
1997 Singapore general elections, PAP candidate Andy Gan had promised residents he would push for the earlier construction of the MRT stations (Potong Pasir and Woodleigh) with the backing of then-
deputy prime minister Lee Hsien Loong and other PAP MPs. In response to his opponents' comments, Chiam said that the PAP was trying to "politicise" the MRT issue and he believed that the MRT stations would still be opened, as the land had been acquired for their construction. Eventually, it was announced by then Transport Minister
Yeo Cheow Tong in February 2002 that the station will be opened with the other NEL stations and the name was finalised as Potong Pasir. Yeo insisted the decision was "based strictly on ridership levels" through a recent review by the
Land Transport Authority (LTA) on projected ridership levels for the NEL stations. The government had denied that the station's opening was related to PAP's bigger share of votes in the 2001 general elections. Contract 705 for the design and construction of the Boon Keng and Potong Pasir two-level civil defence underground stations, of twin bored tunnels and of cut and cover tunnels, was awarded to
Kumagai Gumi-Sembawang Engineering-
Mitsui Joint Venture at a contract value of S$217 million (US$ million). Initially, the station was planned to be just a "
shell station", but it was decided to build the whole station as it would be more expensive for the station to be fitted later. The station was constructed using the top-down method. The construction works required the acquisition of a row of shophouses along Upper Serangoon Road. During the construction, residents had complained about the noise generated from the site, which the LTA Corporate Communications Department answered promptly by giving residents explanations on the works. The station commenced operations on 20 June 2003. Commenting on its opening, Chiam has said it was "not so much a victory for me as a victory for the people of Potong Pasir." Chiam's rival,
Sitoh Yih Pin, has mentioned he was "happy for the residents as they will benefit from the convenience." He mentioned that he had urged the Senior Minister of State for Transport to consider its opening, despite the PAP's loss in the 2001 elections. The residents has also welcomed the station's opening, for it would bring more visitors and businesses to the area. ==Station details==
