The Cross Island Line (CRL) is a high capacity Mass Rapid Transit (MRT) line under development in Singapore. The eighth MRT line, the CRL will run in the general east–west direction from Changi to Jurong Industrial Estate via Loyang, Pasir Ris, Hougang, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi and the West Coast. From Pasir Ris, the line will branch off to Punggol. Coloured lime on official maps, the 58 kilometres (36 mi) line will replace the East West Line as the longest line on the MRT network upon its complete opening by the 2040s, serving roughly about 27 stations. It will be the sixth MRT line to be completely automated and driverless, as well as the fourth high capacity MRT line.
