Paya Lebar MRT station is a Mass Rapid Transit (MRT) interchange station on the East West line (EWL) and Circle line (CCL) in Geylang, Singapore. Despite the name, this station is not located in Paya Lebar but rather along Paya Lebar Road, near the junction with Sims Avenue. It is located among the developments of the Paya Lebar Central commercial hub and near the Geylang Serai district. The station opened on 4 November 1989 as part of the MRT eastern line extension to Tanah Merah station. The EWL station exterior has the characteristic dome-shaped segmented roof also seen on other elevated EWL stations. The station later interchanges with the Circle line on 17 April 2010, and was the first MRT station to serve both an elevated line and an underground line. History East West line The contract for the construction of Paya Lebar station and associated viaducts was awarded to Lee Kim Tah Ltd. at a contract sum of S$59.52 million in November 1985. The contractor had partnered with a French company Societe Generale D'Enterprises Sainrapt Et Brice (SGE) for the construction. The contract also includes the construction of the Kallang and Aljunied stations. The station opened earlier than expected on 4 November 1989, serving the East West line. As with most of the above-ground stations along the EWL, the station was built without platform screen doors. Half-height platform screen doors, which prevent commuters from falling onto the train tracks, were installed on 28 October 2011 and commenced operations on 11 January 2012. In addition, high-volume low-speed fans were installed and started operations since 14 July that year together with Kembangan station. Privacy screens were installed at some parts from Paya Lebar Road all the way to Geylang East Central, to minimise the noise impact from residents since October 2016 and completed in May 2017. Circle line Contract 823 for the construction of Paya Lebar station was awarded to Lum Chang Building Contractors Pte Ltd-Nishimatsu Construction Co. Ltd. joint venture at a contract sum of S$322 million. The contract also includes the construction of the Mountbatten and Dakota stations. Construction of the station started in August 2002.
