Singapore's western land crossing — quieter per vehicle, straight onto the expressway, and in the middle of a multi-year switch to automated clearance right now.
Tuas Checkpoint is Singapore's other land crossing — the western one, at the Singapore end of the Malaysia–Singapore Second Link. It's the crossing most people forget they have the option of, which is often exactly why it's the smarter choice: on the days Woodlands seizes up, Tuas usually stays calmer per vehicle, at the cost of a longer drive for most JB-bound trips.
The Second Link bridges from Tuas across to Tanjung Kupang on the Malaysian side, landing at the Sultan Abu Bakar CIQ complex and feeding straight onto Malaysia's expressway network. That's the key difference from the Causeway: Tuas routes you into western Johor — Iskandar Puteri, Forest City, Legoland, Gelang Patah, Senai — or onward up the North–South Expressway, without threading through JB town at all. If central JB is where you're going, Woodlands is usually more direct; the destination-based call is laid out in Woodlands vs Tuas. Tuas Checkpoint is operated by ICA, same as Woodlands.
Tuas is in the middle of a live upgrade to an Automated Passenger Clearance System (APCS) for vehicles. From 1 September 2026, departure car lanes are being closed and narrowed in phases while the works run, expected to continue into late 2027 — roughly a 15-month rolling programme. Once in place, the system is designed to let drivers clear immigration via QR code and facial biometric verification without handing over a passport or leaving the vehicle. The upside is real, but the transition period means fewer departure car lanes than usual on the Singapore side, so Tuas can back up at times it normally wouldn't — worth factoring in until the works finish.

Because this is active construction, treat lane availability as changeable and check the live crossing rather than assuming a normal layout.
Tuas's reputation as the calmer crossing holds on an ordinary day — but a long weekend, a public holiday, or the current lane works can flip that in an afternoon. General timing patterns are in Best Time to Cross; what the queue is doing right now is only knowable by checking live.
