The Cross Island Line (CRL) is a future high-capacity underground MRT line currently under planning. With the first phase of the line scheduled to open by 2029, it will be the eighth MRT line in Singapore, employing a fully automated and driverless mode of operation.
The line will run from Aviation Park in Changi to Jurong, passing through residential estates such as Loyang, Pasir Ris, Tampines North, Hougang, Serangoon North, Ang Mo Kio, Sin Ming, Bukit Timah, Clementi and West Coast and terminating in the Tuas Industrial Estate. A branch line will connect Pasir Ris and Punggol.
