Dhoby Ghaut MRT station is an underground Mass Rapid Transit (MRT) interchange station on the North South, North East and Circle lines in Singapore. Located beneath the eastern end of Orchard Road shopping belt in Dhoby Ghaut, Museum Planning Area, the station is integrated with the commercial development The Atrium@Orchard. The station is near landmarks such as The Istana, the MacDonald House, Plaza Singapura and Dhoby Ghaut Green. Dhoby Ghaut station was part of the early plans for the original MRT network since 1982. It was constructed as part of Phase I of the MRT network which was completed in 1987. Following the network's operational split, the station has been served by the North South line since 1989. To construct the North East line platforms, which were completed in 2003, the Stamford Canal had to be diverted while excavating through part of Mount Sophia. The Circle line platforms opened in 2010 along with Stages 1 and 2 of the line. Dhoby Ghaut station is one of the deepest and largest stations, with five underground levels. Its deepest point is at below ground. The station features many forms of artworks, three of them under the Art-in-Transit scheme in the North East line and Circle line stations, a set of Art Seats at the Circle line platforms, and an art piece above the North South line platforms. It is also the first triple-line interchange station on the MRT network. History North South line (NSL) station Dhoby Ghaut station was included in the early plans of the MRT network in May 1982. It was to be constructed as part of the Phase I MRT segment from the Novena to Outram Park station; this segment was targeted to be completed by December 1987. Phase I, which would be part of the North South line (NSL), was given priority as it passes through areas having a higher demand for public transport, such as the densely populated housing estates of Toa Payoh and Ang Mo Kio and the Central Area. The line was aimed to relieve the traffic congestion on the Thomson–Sembawang road corridor. Before construction began, tenants of Amber Mansions were compelled to relocate; the land had already been marked for acquisition in 1978. Contract 106 for the design and construction of Dhoby Ghaut NSL station was awarded to a joint venture between French contractor Campenon-Bernard and Singapore Piling and Civil Engineering Company Limited.
