ERP Timings & Rates 2026: Every Gantry in Singapore (Complete Table)

Electronic Road Pricing is Singapore's 1998-era congestion toll that, 28 years on, still quietly sets the tempo of the morning commute. For drivers, the question is not whether ERP exists but how much it costs on your specific route, which hours trigger the highest rates, and whether the forthcoming ERP 2.0 satellite system will change any of that. The answer to the third question is "not initially" — LTA has been clear that the first phase of ERP 2.0 replicates the current gantry model, with distance-based pricing left for a later, unspecified phase.

This guide lays out the 2026 rate structure, the peak-hour timings by expressway, the ERP 2.0 rollout status, which gantries to actually worry about, and the realistic options for avoidance. All figures are drawn from LTA's OneMotoring portal and are subject to quarterly review.

How much does ERP cost?

ERP in 2026 costs between $0.50 and $6.00 per gantry pass, with the exact figure depending on location, time of day, and vehicle type. The most expensive single pass is CTE Southbound at Chin Swee during the 8:00am–9:00am weekday peak, which has sat at $5–$6 across recent quarterly reviews. The majority of expressway gantries charge $1–$3 during their peak windows, and CBD cordon gantries typically $2–$4. Motorcycles pay half the car rate. Heavy vehicles pay 1.5x to 2x.

Indicative 2026 peak-hour rates for major gantries (weekday, car):

Gantry location	Direction	Peak window	Peak rate
CTE — Chin Swee	Southbound (to CBD)	8:00–9:00am	$5–$6
CTE — Braddell Flyover	Southbound	7:30–9:00am	$2–$4
CTE — Serangoon	Southbound	7:30–9:00am	$2–$3
AYE — Alexandra Rd	Eastbound (to CBD)	8:00–9:00am	$3–$5
AYE — Lower Delta	Eastbound	8:00–9:00am	$2–$3
PIE — Adam Rd	Eastbound	8:00–9:00am	$1–$3
PIE — Eunos	Westbound	8:00–9:00am	$1–$2
KPE — Defu	Southbound	7:30–9:00am	$2–$3
BKE — Dairy Farm	Southbound	7:30–9:00am	$1–$2
CBD — Havelock	Into CBD	8:00–10:00am	$2–$4
CBD — Kim Seng	Into CBD	8:00–10:00am	$2–$4
CBD — Shenton Way	Into CBD	8:00–10:00am	$3–$4
ECP — Ophir Rd	Westbound	8:00–9:00am	$2–$3

Rates outside peak windows drop sharply — a gantry charging $5 at 8:30am typically charges $0.50–$1.50 at 7:00am or 10:00am, and nothing at 11:00am. A typical CBD-bound commute can pass 2–4 gantries, producing $6–$12 per morning trip during peak, or $3–$6 if departure is shifted earlier. Check current figures through the ERP Calculator before budgeting, as LTA revises rates every three months based on observed average speeds.

What time does ERP start on CTE?

ERP on CTE Southbound (heading toward the CBD) activates from roughly 7:00am on weekdays, with the highest charges between 8:00am and 9:00am, and tapering off by 9:30am–10:00am. The three gantries to watch are Braddell Flyover, Serangoon, and Chin Swee — the last of which is consistently the most expensive single gantry in Singapore during its 8:00–9:00am window.

CTE Northbound (heading away from CBD) activates in the evening: gantries switch on from roughly 5:30pm and remain active until 8:00pm, with the highest charges between 6:00pm and 7:00pm. The evening peak is less punishing than the morning because traffic disperses faster.

Saturday schedules vary: some CTE gantries run reduced hours (typically a 12:00pm–2:00pm window), others are off entirely. Sundays and public holidays have no CTE ERP charges. The day before a long weekend or public holiday sometimes sees temporary rate adjustments, which LTA announces via OneMotoring and SMS to registered IU holders. Drivers who commute during the edges of peak — arriving at 7:15am or 9:45am — routinely pay half or less what full-peak commuters pay, and that 30-minute shift is the single most effective cost-reduction tactic short of not driving.

Is ERP 2.0 still happening?

Yes — ERP 2.0 is actively rolling out through 2026 and beyond, replacing physical overhead gantries with a satellite-GPS-based system that uses a new on-board unit (OBU) installed in every vehicle. LTA began OBU installation for new vehicle registrations in late 2023 and has continued in phases by vehicle type — motorcycles, taxis, private cars, commercial vehicles — with installation centres operating across the island.

What ERP 2.0 does at launch: replicates the current gantry-based charging model. Same locations (virtually), same peak-hour rates, same quarterly review process. What it enables later: distance-based and cordon-based congestion pricing, real-time rate adjustments based on live traffic, and consolidated payment/account management through a single LTA-linked wallet. LTA has explicitly stated there is 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 (notifications arrive via SMS and mail)
• The new OBU replaces the old IU unit — the old CashCard-based payment transitions to the ERP 2.0 wallet
• Physical gantries are being dismantled as coverage migrates; expect this to be 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

Check your vehicle's specific installation schedule and current status via OneMotoring. Missed installation windows can result in enforcement action, so treat the notification as a hard deadline rather than a suggestion.

Which ERP gantries are most expensive?

The most expensive gantries in 2026 are CTE Southbound Chin Swee ($5–$6 peak) and AYE Eastbound Alexandra Road ($3–$5 peak), followed by the CBD cordon gantries on Shenton Way, Havelock, and Kim Seng ($3–$4 peak). These hit hardest during weekday 8:00am–9:00am and 6:00pm–7:30pm, and are the reason most CBD-bound commutes from the north and west end up paying $8–$12 one-way.

Why these specific gantries? LTA's pricing algorithm adjusts rates quarterly based on measured average traffic speeds during the monitoring window. When speeds drop below 20km/h on expressways (or 45km/h on CBD arterials), rates go up at the next quarterly review; when speeds rise above 30km/h (or 65km/h on arterials), rates go down. Chin Swee and Alexandra consistently record the lowest observed peak speeds because of bottleneck geometry — narrow lanes, merge-heavy stretches, and the sheer volume of city-bound commuters from the northern and western corridors.

Friday afternoons and the last working day before a public holiday often see temporary rate bumps on select gantries. These are announced via OneMotoring but rarely widely publicised; frequent commuters pick them up from traffic-news apps. If you need to travel during one of these premium windows, budget $15–$25 one-way rather than the usual $10.

For reference, the cheapest "useful" ERP gantries are typically on BKE, KJE, and the outer PIE — which charge $0.50–$2 at peak and nothing outside peak. Commuters on these corridors pay a fraction of what CTE and AYE users pay, and the difference over a year is meaningful ($2,000+ annualised for a daily commuter).

Can I avoid ERP on the way to CBD?

Partially — but avoidance typically costs you in time and rarely in a way that works out cheaper once you factor in fuel and vehicle wear. There are three realistic approaches, each with tradeoffs.

Route avoidance. Surface roads into the CBD — Balestier Road, Serangoon Road, Geylang Road — bypass expressway gantries but fight their own congestion. Typical time penalty is 15–30 minutes versus a 20–30 minute expressway trip, meaning your total commute roughly doubles. Fuel cost on stop-start surface roads is also higher. Cordon gantries on the CBD's edge still catch you regardless of which surface route you take.

Time shifting. Leaving before 7:00am or after 9:30am cuts ERP cost by 50%–100%. A 7:00am departure on CTE Southbound typically pays $0.50 where an 8:30am departure pays $5. For drivers with flexible start times, this is the single most effective strategy — $2,000+/year saved on a daily commute.

Mode shifting. MRT and bus cover the CBD comprehensively and cost $2–$3 per trip versus $8–$12 in ERP plus parking. For trips that do not require a car at the destination, this is often the dominant option. Park-and-ride at outer MRT stations (with the HDB Parking Fee Calculator helping you budget that end) can combine the convenience of a car for the first leg with MRT for the CBD leg.

For frequent CBD commuters who must drive, total ERP cost typically runs $120–$240/month. Parking in the CBD runs $300–$600/month on top. If your employer offers flexible hours or hybrid work even twice a week, you can cut both by 40%+ without changing vehicle or route. Run your specific patterns through the ERP Calculator alongside parking costs to see your full monthly CBD-access bill.

Bottom line

ERP in 2026 is a known, quantifiable cost rather than a mystery. The three things that actually matter for your wallet: which gantries sit on your route, what time you cross them, and whether your employer's work hours allow for time-shifting away from the 8:00–9:00am peak. 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. For budget planning, the two useful tools are the ERP Calculator for per-trip and monthly totals, and a parking calculator for the other half of the CBD commute equation. 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.
