The Cross Island Line (CRL) is a high capacity Mass Rapid Transit (MRT) line under development in Singapore. It will run in an east–west direction from Changi to Jurong Industrial Estate via Loyang, Pasir Ris, Hougang, Serangoon North, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi and West Coast. From Pasir Ris, the line will branch off to Punggol.^[2] The 58-kilometre (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 about 27 stations.^[3]

Plans for the line were first announced in 2013. The CRL is envisioned to serve various key hubs including the Jurong Lake District and the Punggol Digital District, offering an alternative east–west connection to alleviate passenger load on the East–West Line. Shortly after the announcement, calls were made by some nature groups to divert the line tunnels away from the Central Catchment Nature Reserve (CCNR). Nevertheless, the Government ultimately decided after years of assessments and deliberation to continue with the original direct route in 2019, citing commuting time and economic factors as well as long-term energy consumption. The alignment and stations for CRL1 were finalised in 2019, followed by the Punggol branch in 2020 and Phase 2 in 2022.^[4] The proposed full line is expected to have a daily ridership of over one million in the long term,^[5] and to cost an estimated S$40.7 billion.^[6]
