ERP Timing 2026 Singapore: Every Gantry by Expressway (CTE, AYE, KPE, PIE, BKE)

ERP timing in Singapore 2026: weekday morning peak runs 7:00am–9:30am with the highest charges (up to $6 per gantry) between 8:00am–9:00am on CTE Southbound (Chin Swee) and AYE Eastbound (Alexandra). Evening peak runs 5:30pm–8:00pm on northbound/outbound corridors. Saturdays have reduced schedules; Sundays and public holidays = no ERP except select CBD locations.

Use the ERP Calculator to model your specific route + departure time.

Peak-hour ERP rates by gantry (2026 reference)

Indicative weekday-car rates. Motorcycles half-rate, heavy vehicles 1.5–2×. Rates revised quarterly by LTA.

Rates outside peak windows typically drop to $0.50–$1.50, then $0 outside the operating window. A typical CBD-bound peak commute crosses 2–4 gantries = $6–$12 one-way.

CTE ERP timing 2026

CTE Southbound (heading toward CBD) activates from 7:00am on weekdays, with peak charges between 8:00am and 9:00am, tapering off by 9:30am–10:00am. The three gantries to know: Braddell Flyover ($2–$4 peak), Serangoon ($2–$3), and Chin Swee ($5–$6 — the most expensive single gantry in Singapore).

CTE Northbound (away from CBD) activates 5:30pm–8:00pm, peaking 6:00pm–7:00pm. Less punishing than the morning because evening traffic disperses faster.

Saturdays: reduced schedules — typically a 12:00pm–2:00pm window on some gantries, others off entirely.

Sundays + Public Holidays: no CTE ERP. The day before a long weekend can see temporary rate bumps on key corridors — LTA announces these on OneMotoring.

For frequent CTE commuters, the simplest mitigation is time-shifting: a 7:00am departure typically pays $0.50 at Chin Swee where an 8:30am departure pays $5. Across a year, that's $2,000+ in saved ERP without changing route.

AYE ERP timing 2026

AYE Eastbound (toward CBD) activates around 7:30am with peak charges 8:00am–9:00am. The two gantries that matter: Alexandra Road ($3–$5 peak — the second-most expensive single gantry in Singapore) and Lower Delta ($2–$3). Alexandra Road has been raised in successive quarterly reviews because monitored speeds consistently fall below 20km/h during peak.

AYE Westbound (away from CBD) has lighter evening peak charges 6:00pm–7:30pm.

Saturday + Sunday: broadly no AYE ERP, with rare exceptions for special events.

Why AYE Eastbound is expensive: traffic from Tuas, Jurong, Boon Lay and the west converges at Alexandra during the morning peak, creating a structural bottleneck. The geometry of the lanes here means even small congestion increases trigger sharp speed drops.

KPE ERP timing 2026

KPE Southbound (toward Marina Bay / CBD) at Defu activates around 7:30am with peak rates 7:30am–9:00am ($2–$3 in 2026). The KPE tunnel section keeps traffic moving better than CTE or AYE, so monitored speeds stay above LTA's escalation threshold and rates stay moderate.

KPE Northbound (away from CBD) has light evening peak charges, primarily during 6:00pm–7:30pm.

Sundays + Public Holidays: no KPE ERP.

KPE is the cheapest "useful" CBD-bound expressway corridor for drivers coming from the northeast (Hougang, Sengkang, Punggol). Compared to CTE Southbound, a Defu pass saves $2–$4 per morning trip vs Chin Swee.

PIE ERP timing 2026

PIE Eastbound (toward Changi, but also feeding into the CBD via Bendemeer/Lavender) — the Adam Road gantry activates around 7:30am with peak rates 8:00am–9:00am ($1–$3 in 2026).

PIE Westbound (toward Tuas / Jurong) — the Eunos gantry has lighter peak charges, typically $1–$2 in the same morning window.

PIE rates are generally lower than CTE/AYE because the expressway is longer (E–W across the island) and traffic disperses across multiple exits. PIE commuters coming from the east (Bedok, Tampines) face lower total ERP than those coming from the north.

Sundays + Public Holidays: no PIE ERP.

BKE / KJE ERP timing 2026

BKE Southbound (toward CTE) at Dairy Farm activates around 7:30am with peak rates 7:30am–9:00am at $1–$2.

KJE has light gantries that activate in similar windows at $0.50–$1.50.

These are the cheapest expressway gantries in the system — drivers from the northwest (Choa Chu Kang, Bukit Panjang, Woodlands) face lower total ERP than CTE/AYE commuters by a meaningful margin (~$2,000/year saved).

CBD cordon ERP timing

CBD cordon gantries — Havelock, Kim Seng, Shenton Way, Ophir, Bras Basah — activate from 8:00am–10:00am weekday morning peak at $2–$4. They catch you regardless of which expressway brought you in. Evening reverse peak runs 6:00pm–7:30pm on outbound directions.

The reason CBD cordon gantries persist alongside expressway gantries: they price the marginal congestion of crossing into the central business district, on top of the expressway-segment charges. A drive from Toa Payoh to Raffles Place typically pays one expressway gantry (CTE Chin Swee) plus one CBD cordon gantry (Shenton or Havelock).

Saturdays: typically no CBD cordon ERP.

Is ERP 2.0 still happening?

Yes — ERP 2.0 is actively rolling out through 2026 and beyond. It replaces physical overhead gantries with a satellite-GPS-based system using a new On-Board Unit (OBU) installed in every vehicle. LTA began OBU installation for new registrations in late 2023 and continues in phased waves by vehicle category — motorcycles, taxis, private cars, commercial vehicles.

What ERP 2.0 does at launch: replicates the current gantry-based charging model. Same virtual locations, same peak-hour rates, same quarterly review process. The OBU just enables collection without the overhead arch.

What it enables later: distance-based and dynamic congestion pricing, real-time rate adjustments based on live traffic, consolidated payment via an LTA-linked wallet. LTA has explicitly stated no distance-based charging in the initial rollout — a message repeated in multiple parliamentary responses to dampen public concern.

Practical implications for drivers in 2026:

• Book your OBU installation within the window LTA notifies you of (SMS + post)
• The new OBU replaces the old IU. CashCard payment migrates to the ERP 2.0 wallet
• Physical gantries are being progressively dismantled — expect this largely complete by 2027–2028
• Existing ERP charges continue on legacy gantries until each corridor fully transitions
• No additional charges during the rollout — LTA has committed to cost-neutral migration

Missed installation windows can result in enforcement action. Treat the notification as a hard deadline.

How to avoid ERP on the way to CBD

Three realistic approaches, each with tradeoffs:

1. Time-shift. Leaving before 7:00am or after 9:30am cuts ERP by 50%–100%. A 7:00am Chin Swee crossing pays $0.50 where 8:30am pays $5. For flexible workers, this is the single most effective tactic — $2,000+/year saved.

2. Route-avoid via surface roads. Balestier, Serangoon, Geylang bypass expressway gantries — but fight surface congestion and add 15–30 minutes. CBD cordon gantries still catch you on the way into the district. Time penalty rarely worth the dollars saved.

3. Mode-shift. MRT and bus cover CBD comprehensively at $2–$3 per trip vs $8–$12 ERP plus $300–$600/month parking. For trips that don't require a car at the destination, this is the dominant option. Park-and-ride at outer MRT stations combines convenience with cost.

For frequent CBD commuters who must drive, total ERP runs $120–$240/month before parking. Hybrid work even twice a week cuts that 40%+. Run your specific patterns through the ERP Calculator.

Bottom line

ERP in 2026 is a known, quantifiable cost — not a mystery. Three things matter: which gantries sit on your route, what time you cross them, and whether time-shifting is an option. ERP 2.0 is real and rolling out, but at launch it replicates current pricing — not a tactical consideration for 2026. The migration to OBUs is mandatory; book your installation when notified.

Re-check rates quarterly — LTA's reviews can add or subtract $40–$80/month from a frequent commuter's bill without any change in your driving pattern. Pair the ERP Calculator with the HDB Season Parking Calculator for the full monthly cost of CBD access.
