The Johor Bahru–Singapore Rapid Transit System (RTS) Link is an upcoming 4 km (2.5 mi) long, twin-track rapid transit system crossing the Strait of Johor between Malaysia and Singapore. It will link Johor Bahru, Malaysia, at Bukit Chagar station, with the Singapore MRT at Woodlands North station in Woodlands. The line is planned to open in December 2026.
To provide a seamless pre-boarding clearance, both of the line's stations will house customs, immigration and quarantine (CIQ) facilities for both countries, which will be independent from the existing CIQs at the Sultan Iskandar Building and Woodlands Checkpoint.
