Ang Mo Kio Bus Interchange is located in Ang Mo Kio Town Centre, Singapore. The interchange is within AMK Hub which is in turn linked to Ang Mo Kio MRT station via a pedestrian underpass below Ang Mo Kio Avenue 8. The interchange was opened by Prime Minister Lee Hsien Loong. The interchange is the third to be fully air-conditioned in Singapore after the Toa Payoh Bus Interchange and the Sengkang Bus Interchange, and similarly features automated sliding doors at each of its six berths that will open only when the bus reaches the berths. History Original interchange Plans for the bus interchange were first announced in March 1979, as part of the Singapore Bus Service's (SBS) efforts to rationalise the Singapore bus system. Constructed by the Housing and Development Board (HDB), the bus park of the interchange was completed in 1979. In January 1980, bus services that previously terminated at a bus terminus along Ang Mo Kio Avenue 6 were amended to the interchange, but passengers were not allowed to board or alight at the interchange. Due to concerns over the interchange's small size making it unsafe for commuters, in August 1980, SBS announced that it would be replacing the interchange with a larger facility. To facilitate the interchange's construction, the HDB granted permission to SBS to utilise half of a plot of land beside the interchange and another plot then occupied by a carpark. Work on the replacement bus interchange commenced in January 1981, and operations at the new interchange commenced on 10 April 1983. Covering an area of more than and with 36 berths, the bus interchange included features such as swing gates and turnstiles to handle commuter traffic, along with safety railings and walls to ensure commuters' safety. Current interchange In 2001, the government announced plans to redevelop the bus interchange to form part of an integrated development, and to make way for the development, the interchange was moved to a temporary location along Ang Mo Kio Avenue 8 in March 2002. Construction of the integrated development was delayed by a dispute between the developer and the government over the price of the land parcel, only beginning in March 2005. Subsequently, the new bus interchange within the integrated development started operations in April 2007. Bus Contracting Model Under the new bus contracting model, the entire bus interchange except 22, 25, 73, 86, 136, 166 and 169
