The worst times to cross the Causeway in 2027 are likely to be the Chinese New Year week (5–12 February), the Hari Raya Puasa and March school holiday stretch (6–21 March), the Labour Day to Hari Raya Haji and Vesak weeks (30 April–23 May), the overlapping June school holidays (22 May–27 June), late August to mid-September, Deepavali (27–31 October) and the December holidays. On ordinary days, Singapore-bound traffic peaks before and around dawn, and JB-bound traffic peaks in the evening, especially on Fridays and before public holidays. Midweek mid-mornings outside school holidays are usually the calmest.
This Causeway jam calendar for 2027 combines the official 2027 public holidays of Singapore (MOM), Malaysia and the state of Johor, plus the 2027 school calendars from Singapore’s MOE and Malaysia’s KPM, into one month-by-month plan. The patterns described come from ICA’s published traffic advisories and news reports from 2025 and 2026; actual waits vary every day with weather, incidents and enforcement checks, so treat this as a planning guide rather than a forecast. For the rules on QR codes, arrival cards and vehicle permits, see our JB–Singapore border crossing guide.
Why does the Causeway jam? What the 2026 numbers show
The Causeway jams when holiday travellers stack on top of the daily commuter flow. About 350,000 people use the Causeway every day, The Star reported in April 2026, and holiday peaks push the two land checkpoints far higher.
- Over the Labour Day long weekend (30 April–3 May 2026), more than 2 million travellers crossed Woodlands and Tuas, with close to 580,000 on 30 April alone (ICA).
- On 4 September 2026, the first day of Singapore’s September school holidays, more than 599,000 travellers cleared the land checkpoints, a new daily record (ICA). More than 6.1 million crossed during that holiday period.
- At peak hours, car travellers leaving Singapore waited up to three hours for clearance because of tailbacks from Malaysia, ICA said in its 2026 advisories.
- ICA has tightened security checks at all checkpoints since 28 February 2026, and warns that this can lengthen waits at peak times.
Two things work in your favour. QR clearance and facial recognition for motorcyclists raised departure-peak throughput by more than 35% compared with 2019, about 7,600 more travellers per hour, ICA said. On the Malaysian side, MyNIISe had recorded more than 19.48 million QR transactions at BSI and KSAB by June 2026, which the Home Minister said had eased congestion.
Daily patterns: best and worst times of day to cross
On a normal working day, the heaviest Singapore-bound flow is from before dawn to early morning, and the heaviest JB-bound flow is in the evening. Published reports describe commuters aiming to reach the BSI CIQ before 6am, with morning bus-hall waits of up to an hour and 30–40 minute waits common even after 6am (The Star, 2026). Evening return trips in heavy traffic can take up to three hours, according to the same report.
| Time window | JB → Singapore | Singapore → JB |
|---|---|---|
| Before 6am (weekdays) | Busy: commuter wave builds | Usually light |
| 6am–9am (weekdays) | Peak: longest queues of the day | Light to moderate |
| 10am–3pm (midweek) | Usually the calmest window | Usually calm |
| 5pm–10pm (weekdays) | Moderate | Peak: commuters return to Johor |
| Friday evening and eve of holidays | Moderate | Heaviest: commuters plus weekend visitors |
| Sunday evening and last day of holidays | Heavy: visitors and workers return to Singapore | Moderate |
ICA’s standing advice is to travel outside peak hours, such as early mornings or late evenings, and to check live conditions before setting off. Pattern summary based on ICA advisories and news reports; it is not an official timetable.
2027 public holidays: Singapore, Malaysia and Johor
Jams cluster around public holidays in both countries, so you need both lists. Singapore has 11 public holidays in 2027 (MOM, June 2026). Malaysia’s national list and Johor’s state holidays were announced by the Prime Minister’s Department in August 2026, as circulated by the Federation of Malaysian Manufacturers. Johor’s weekend has been Saturday–Sunday since 1 January 2025, the same as Singapore’s, so weekends on both sides now line up.
| Date (2027) | Day | Singapore | Malaysia / Johor |
|---|---|---|---|
| 1 Jan | Fri | New Year’s Day | Not on Johor’s holiday list |
| 22 Jan | Fri | – | Thaipusam (Johor) |
| 6–7 Feb | Sat–Sun | Chinese New Year (Mon 8 Feb in lieu) | Chinese New Year (national) |
| 8 Feb | Mon | Public holiday in lieu | Awal Ramadan (Johor, date subject to change) |
| 10–11 Mar | Wed–Thu | Hari Raya Puasa (10 Mar only) | Hari Raya Puasa (both days) |
| 23 Mar | Tue | – | Sultan of Johor’s Birthday (Johor) |
| 26 Mar | Fri | Good Friday | – |
| 1 May | Sat | Labour Day | Workers’ Day |
| 17 May | Mon | Hari Raya Haji | Hari Raya Qurban |
| 20 May | Thu | Vesak Day | Wesak Day |
| 6–7 Jun | Sun–Mon | – | Awal Muharram (Sun), Agong’s Birthday (Mon) |
| 11 Jul | Sun | – | Hol Day of Almarhum Sultan Iskandar (Johor) |
| 9 Aug | Mon | National Day | – |
| 15 Aug | Sun | – | Prophet Muhammad’s Birthday |
| 31 Aug | Tue | – | National Day (Merdeka) |
| 16 Sep | Thu | – | Malaysia Day |
| 28 Oct | Thu | Deepavali | Deepavali |
| 25 Dec | Sat | Christmas Day | Christmas |
Malaysian holidays that fall on a Sunday are generally replaced by the next working day, so expect replacement Mondays or Tuesdays around 7 February, 6 June, 11 July and 15 August in Johor. Confirm the final replacement dates with the official state list closer to the time.
2027 school holidays in Singapore and Johor
School holidays are the biggest jam drivers because families travel for days, not hours. When Singapore’s and Malaysia’s breaks overlap, both directions get busy at once.
| Break | Singapore (MOE primary and secondary) | Malaysia (KPM Group B, incl. Johor) | Overlap |
|---|---|---|---|
| March | 13–21 Mar | 6–14 Mar (Term 1 break) | 13–14 Mar |
| Mid-year | 29 May–27 Jun | 22 May–6 Jun | 29 May–6 Jun |
| August / September | 4–12 Sep | 28 Aug–5 Sep (Term 2 break) | 4–5 Sep |
| Year-end | 20 Nov–31 Dec | 4–31 Dec | 4–31 Dec |
Extra school-only days also add traffic. Malaysia’s KPM gives Group B schools extra Chinese New Year days on 5 and 9–12 February, Hari Raya Korban days on 18–19 May, Wesak on 21 May and Deepavali days on 27 and 29 October (as published from KPM’s 2027 academic calendar). Singapore’s MOE adds Youth Day (5 July), the day after National Day (10 August), Teachers’ Day (3 September), Children’s Day for primary schools (8 October) and off-in-lieu days on 9 February, 3 May and 27 December. Malaysia’s 2027 school year runs from 4 January to 3 December for Group B states, KPM said.

How ICA warns about festive jams, and where to check live traffic
ICA issues a public advisory before almost every long weekend and school holiday, typically a few days ahead, naming the dates when it expects heavy traffic at Woodlands and Tuas. In recent years it has issued advisories for Chinese New Year, the Qing Ming and Good Friday period, the March holidays with Hari Raya Puasa, Hari Raya Haji with the June holidays, the September holidays and Deepavali, most recently for 6–9 November 2026. Expect a similar rhythm in 2027.
ICA lists these sources for checking conditions before you set off:
- LTA’s OneMotoring website and its checkpoint traffic cameras.
- The Expressway Monitoring and Advisory System signs on the BKE and AYE.
- ICA’s official Facebook and X accounts.
- Traffic reports on SPH and Mediacorp radio stations.
ICA also enforces against queue-cutting: drivers caught are made to U-turn and rejoin the back of the queue, and serious cases can be referred to the Traffic Police or face entry bans.
Tips to beat the jam in 2027
The most reliable ways to save time are preparation, timing and, from 2027, the RTS Link.
- Get your QR codes ready. Use MyICA for the Singapore side and MyNIISe (or MyBorderPass for Malaysians) for the Malaysian side, and generate them before you reach the checkpoint.
- Shift your timing. Avoid Friday evenings JB-bound and Sunday evenings Singapore-bound on long weekends; midweek mid-mornings are usually quietest.
- Do your paperwork early. Foreign visitors should submit the SG Arrival Card and MDAC within three days before arrival; drivers need a valid VEP, and Singapore’s VEP fees rise from 1 January 2027.
- Check live traffic using the sources above before you leave home.
- Plan around the RTS Link. Passenger service is targeted for February 2027, with clearance for both countries done once at the departure station. The fare has not been announced; follow our RTS Link latest news page, and see how long JB to Woodlands takes by RTS.
How should different travellers plan their crossing?
The same calendar means different things for different people. Daily commuters benefit most from a fixed early routine and from avoiding Friday evenings; during school holidays, allow extra time because holiday traffic spills into commuter hours. Singapore families visiting JB for the weekend usually leave on Friday evening and return on Sunday evening, exactly when queues peak, so a Saturday-morning start and a Sunday-midday or early-Monday return can save a lot of time. Drivers should check the OneMotoring checkpoint cameras before leaving and consider the Second Link when the Causeway is backed up. First-time foreign visitors cannot use QR codes on their first entry, so they gain most from crossing midweek in the morning with their arrival cards already submitted.
The long-term answer to Causeway jams: live within walking distance
The most effective jam-beater is not an app but an address. Residents who can walk to the CIQ and the RTS Bukit Chagar station avoid the road queues on the Johor side entirely. Causewayz Square by EXSIM is about 600 m from the BSI CIQ and about 800 m from the RTS Bukit Chagar station, and the developer has proposed a pedestrian link bridge towards the CIQ and RTS. Target completion is around 2030.
For Singapore-based workers, that location can turn the daily crossing into a short walk plus a five-to-six-minute train ride, which is why homes near the RTS have historically drawn strong interest from commuter tenants. Our day-in-the-life walkthrough for Singapore commuters shows how such a routine could look once the RTS is running. WhatsApp us for the latest SPA price list and unit availability.
