Both link Singapore to Johor Bahru, but they serve different routes, cost differently, and behave very differently under traffic pressure. Here's how to pick.
Woodlands Causeway is shorter and toll-free from the Singapore side, and it drops you directly into central Johor Bahru. Tuas Second Link is longer and costs more in tolls, but it has more customs capacity relative to its traffic volume, and it's the better route toward Iskandar Puteri, Legoland, and destinations further up the west coast.
| Woodlands Causeway | Tuas Second Link | |
|---|---|---|
| Bridge length | 1.05 km | ~1.9 km |
| SG side toll | S$0.00 | S$2.10 (peak) / S$1.10 (off-peak) |
| MY side charge | RM 20.00 road charge | RM 6.14 + RM 20.00 road charge |
| Best for | Central & East JB, JB Sentral | Iskandar Puteri, Legoland, KL-bound trips |
| Typical peak behavior | Heaviest during commuter rush | Generally more headroom at peak |
| Motorbike lanes | Yes, biometric clearance | Yes, dedicated M-Bike lanes |
If your destination is JB Sentral, the city center, or anywhere directly off the Bukit Timah Expressway corridor, Woodlands is almost always the more direct route — and it's free on the Singapore side. The tradeoff is that it also carries the bulk of daily commuter traffic, so it's the checkpoint most prone to long queues during the 6:30-8:30am and 5:30-8pm windows.
Tuas Second Link is the better choice heading toward Iskandar Puteri, Legoland Malaysia, or further north toward Kuala Lumpur via the North-South Expressway — it lines up with the AYE on the Singapore side rather than requiring a detour through central JB. It's also frequently the less congested option during peak hours precisely because fewer daily commuters use it, even though the toll cost is higher.
Static advice only goes so far — congestion flips between the two checkpoints depending on incidents, enforcement operations, and time of day. The most reliable approach is checking real-time clearance estimates for both checkpoints before you commit to a route.
LTA's own OneMotoring portal publishes the raw traffic camera feeds for both checkpoints, but it's just a static image grid — no queue estimate, no side-by-side comparison, and no recommendation on which checkpoint is actually faster. CausewayRadar pulls the same government camera and travel-time data and turns it into a direct answer: which checkpoint to take, right now.
