Singapore’s ERP Gantries Are Coming Down: What Every Driver Needs to Know About ERP 2.0

Introduction

If you have driven anywhere in Singapore this October, you may have already spotted something different on the roads. The familiar overhead gantries – those towering structures that have defined Singapore’s expressways and city roads since 1998 – are starting to disappear. In their place, keep an eye out for blue oval road markings and new ‘ERP Charge Zone’ signs. This is not a minor road-works project. It is the beginning of the most significant transformation to Singapore’s road pricing infrastructure in nearly three decades.

On 28 September 2026, the Land Transport Authority (LTA) confirmed that from October 2026, new ERP road markings and signs would be progressively installed across Singapore’s roads, ahead of the full launch of the satellite-based ERP 2 system on 1 January 2027. Simultaneously, the physical removal of ERP gantries began this month – starting with 62 non-operational gantries, followed by the remaining 33 active ones after gantry-based charging ceases on 31 December 2026. All 95 gantries are expected to be modified or removed by June 2027.

For everyday motorists, the change raises immediate practical questions. What exactly is changing on the road? Will you be charged differently? What do the blue markings mean? Do you need to do anything before 1 January 2027? And looking further ahead – is distance-based road charging coming, and what would that mean for the cost of driving in Singapore?

In this article, we break down everything Singapore motorists and car rental customers need to know about the ERP 2 transition – from the visible changes happening on the roads right now, to the longer-term implications of a fully-satellite-based road pricing future.

Key Takeaways

• ERP gantries are being progressively removed from October 2026, starting with 62 non-operational ones in October. The remaining 33 active gantries will come down after 31 December 2026, with all 95 expected gone by June 2927.
• Blue oval ‘ERP’ road markings and ‘ERP Charge Zone’ signs are being installed from October 2026 across all 33 current ERP charging locations to replace gantries as the visual indicator of a priced zone.
• ERP 2 launches fully on 1 January 2026. All Singapore-registered vehicles must have the new On-Board Unit (OBU) installed by that date. As of September 2026, more than 98% of eligible vehicles are already fitted.
• Charges are NOT changing on 1 January 2027. ERP 2 launches with the same zone-based charging approach as the current system. You will not be charged for how far you drive – only for passing through designated charging zones during congested periods.
• Distance-based charging is not imminent. LTA and the Ministry of Transport have confirmed there are no immediate plans for distance-based road pricing. It remains a future policy option that is still several years away.
• The OBU does far more than just ERP. It also handles EPS carpark payments, checkpoint tolls, off-peak car usage licenses, and roadside parking, replacing the older In-Vehicle Unit (IU) entirely.
• For car rental customers, no additional action is needed. Rental vehicles from reputable operators are already OBU-equipped. ERP charges apply normally during your rental period.

A Brief History: Why Singapore Built Gantries in the First Place

The World’s First Electronic Road Pricing System

To appreciate why the gantries are coming down, it helps to understand why they went up. Singapore introduced the world’s first urban congestion charging system – the Area Licensing Scheme – in 1975. Drivers who wanted to enter the Central Business District during peak hours had to buy a paper license and display it on their windscreen. By the early 1990s, this manual system was being overwhelmed by rising car ownership and traffic volumes. 

In 1998, Singapore replaced it with the Electronic Road Pricing system – the world’s first fully automated, electronic congestion pricing system. ERP used a network of overhead gantries equipped with sensors that could read an In-Vehicle Unit (IU) fitted to every Singapore-registered car. When a car passed under a gantry during operational hours, the applicable charge was automatically deducted from a stored-value CashCard in the IU.

The system was a genuine breakthrough, and Singapore became an international benchmark for urban traffic management. For nearly three decades, the gantries became as much a part of Singapore’s road landscape as traffic lights – so familiar that most drivers barely noticed them.

Why the System Needed to Change

But the infrastructure that was revolutionary in 1998 has been running on ageing hardware for far too long. The gantries are costly to maintain. Each new charging location requires the physical construction of a gantry – a multi-million-dollar infrastructure commitment. The IU technology is decades old. And critically, the current system can only charge at fixed physical points, limiting its flexibility as a congestion management tool.

LTA announced as far back as 2013 that it was planning a GNSS-based successor. The development and procurement process took years. OBU installation began in late 2023 and has been rolling out across the fleet since. As of September 2026, more than 98% of eligible Singapore-registered vehicles have been fitted with the new OBU – laying the hardware foundation for a clean switchover on 1 January 2027. 

What is Actually Changing on Singapore’s Roads Right Now

The Blue Markings: What They Look Like and What They Mean

From October 2026, motorists are progressively seeing new blue oval ‘ERP’ symbols painted directly onto road lanes across Singapore. These oval markings indicate that a vehicle is entering or passing through an ERP charging location. At the start of each zone, a new ‘ERP Charge Zone’ road sign is also installed as an additional visual cue.

LTA tested several design options during a two-phase user experience study from March to July 2026. The first phase at Bayshore Drive in March tested options including a 25-metre stretch of road painted entirely blue and a blue oval ‘E’ symbol. The second phase ran from June to July at five expressways and arterial roads, testing different combinations of markings and signs across the CTE, PIE, Marina Boulevard, AYE, and Tampines Expressway.

The study confirmed that road markings and signs effectively help motorists identify ERP charging locations without gantries. The settled design uses the blue oval ‘ERP’ lane symbol as the primary marking, with the ‘ERP Charge Zone’ sign at zone entry points. These visual cues work in tandem with OBU notifications, which will alert drivers before they enter a charging location, display the prevailing charge, and confirm the amount deducted when they pass through. Three layers of information – road marking, zone sign, and OBU dashboard alert – replace the single overhead gantry. 

The Gantry Removal Timeline

It is worth noting that while gantry structures are being removed, some frames may be retained and repurposed as mounting structures for Roadside Units (RSUs) that support satellite connectivity for the new system. The visual transformation of Singapore’s expressways will be striking – but the infrastructure footprint does not disappear entirely overnight.

The Remaining ERP Charging Zones

As of October 2026, only 33 ERP locations remain in active operation, down from 93 at the system’s peak. From January 2027, these will be renamed ‘road charging zones’ under the ERP 2 framework. Active zones are concentrated on the AYE, CTE, KPE, and MCE – the expressways where congestion management remains a genuine, persistent need. The many other gantry locations that have sat inactive for years will simply be removed without replacement.

ERP 2.0: How the New System Actually Works

GNSS Technology: Satellites Replace Structures

The fundamental shift in ERP 2 is from physical detection to satellite positioning. Under the current system, a gantry physically detects when your IU passes beneath it. Under ERP 2, your OBU communicates with the Global Navigation Satellite System (GNSS) to determine your vehicle’s precise location in real time. When your vehicle enters a designated ERP charging zone, the OBU recognizes the location and processes the applicable charge automatically – no overhead structure required.

This is a far more flexible architecture than gantries allowed. New charging locations can be activated or deactivated by creating or removing ‘virtual zones’ in software at a fraction of the cost of building a physical gantry. Charging rates can be adjusted with greater granularity. The system can respond to real-time traffic conditions more dynamically than any fixed-point network could manage.

Your On-Board Unit (OBU): What It Does

The OBU is the hardware centre-piece of ERP 2. Unlike the older IU, which was a simple stored-value card reader, the OBU is a three-component system for cars – an antenna unit, a processing unit, and an optional touchscreen display. Motorcycles use a single-piece OBU. The antenna, mounted on the windscreen, communicates with the GNSS satellite network. The processing unit handles charge calculation and payment. The display provides real-time ERP information, road safety alerts, speed camera notifications, silver zone and school zone reminders, and bus lane indicators.

Beyond ERP charging, the OBU also handles Electronic Parking System (EPS) carpark payments, checkpoint tolls at Woodlands and Tuas (for Singapore-registered vehicles), off-peak car usage licenses, and roadside parking. It is, in fact, a complete replacement for the entire ecosystem of transport-related in-car devices Singapore motorists have accumulated over the years.

Missed ERP Charges: Decriminalized

One meaningful improvement in ERP 2 is how missed charges are handled. Under the old gantry system, failing to have sufficient CashCard funds when passing a gantry was a criminal offence under the Road Traffic Act – a remarkably punitive position for what is often a simple oversight. The Land Transport and Related Matters Bill, introduced in Parliament in 2026, decriminalizes missed ERP charges and simplifies settlement. Motorists who miss a charge can clear it directly via their OBU at the click of a button. This practical reform acknowledges that a satellite-based system processing many smaller charges across multiple locations needs a more forgiving mechanism than the gantry-era model.

Foreign Vehicles

Foreign-registered vehicles crossing from Malaysia can install the Singapore OBU from April 2026 at S$158.70 plus installation fees, enabling seamless ERP charge integration. Vehicles without an OBU will pay a flat daily ERP rate of S$3 for motorcycles and S$10 for all other vehicles from 2027. Malaysia taxis are required to install the OBU for enforcement and tracking purposes. For regular cross-border drivers, the OBU installation is likely to be more economical than the daily flat rate on multi-day visits.

The Question Every Motorist Is Asking: Will I Pay More?

On Launch Day, 1 January 2027: No

LTA and the Ministry of Transport have been consistent and clear on this point: ERP 2 launches with the same zone-based charging framework as the current system. You are charged for passing through designated zones during peak periods, not for how far you drive or how long you spend on the road. The satellite technology changes the infrastructure behind the system entirely – but the charging philosophy and the specific active zones remain the same at the point of transition.

Acting Minister for Transport Jeffrey Siow confirmed in Parliament that the government will be ‘judicious’ about adding new charging zones under ERP 2, with additions only at ‘persistent congestion hotspots’. The satellite capability to create virtual charging zones anywhere does not mean LTA intends to do so broadly. Any expansion of charging locations will require deliberate policy decisions and appropriate public communication.

Distance-Based Charging: The Future Option That Is Not Yet Here

ERP 2’s GNSS technology provides the technical capability for distance-based charging – a model where you pay for every kilometre driven, factored by location, time of day, and road conditions. This would represent a fundamental shift in how Singaporeans pay for road use: from a charge triggered at specific fixed points to a charge that accrues with every kilometre on priced roads.

The government’s messaging has been explicit and repeated: distance-based charging is not coming in the immediate term. MOT’s written parliamentary reply in March 2026 stated clearly that the priority is giving motorists time to adjust to ERP 2 first, and that distance-based charging requires careful study of its impact on professional high-mileage drivers – taxi drivers, delivery workers, private-hire operators – before any decision is made. When and if it does arrive, Acting Minister Siow confirmed, adequate notice will be provided.

For motorists and businesses, the key takeaway is this: ERP 2 lays the groundwork for distance-based charging as a future policy option. It is not a surprise awaiting you on 2 January 2027. Transport analysts generally expect it to arrive eventually, but there is no committed timeline, and any implementation will come with accompanying measures – likely including road tax restructuring and relief for affected groups.

What This Means for Car Rental Customers

For Renters: A Seamless Transition

If you rent a Singapore-registered vehicle from Asia Car Rental or any reputable rental operator, the ERP 2 transition requires nothing from you. Our fleet vehicles are Singapore-registered and fitted with the OBU as required. ERP charges incurred during your rental period are processed automatically through the OBU – exactly as they were through the older IU. The visual experience on the road changes in October 2026: you will see blue oval markings at lane level and ‘ERP Charge Zone’ signs where you once looked up for an overhead gantry. But the charging mechanism is entirely unchanged on 1 January 2027.

For customers who relied on spotting gantries overhead as a visual reminder of ERP zones, the adjustment is simple. Watch for the blue oval ‘ERP’ symbols on the road surface and the ‘ERP Charge Zone’ signs as you approach a zone entry. Your OBU will also alert you before you enter a charging location and confirm the amount charged as you pass through. Between the road marking, the entry sign, and the OBU notification, you have multiple layers of advance warning – arguably better information than a single overhead gantry ever provided.

For the Rental Industry: Lower Infrastructure Friction

At the fleet management level, ERP 2 removes the need for rental companies to manage CashCard top-ups for IU devices – an administrative friction point under the current system. The OBU’s integrated payment capability and the decriminalization of missed charges create a more streamlined process for operators managing large fleets.

More significantly, ERP 2’s ability to activate new virtual charging zones without physical infrastructure gives LTA greater flexibility to manage congestion across Singapore’s road network. For rental operators whose fleets operate extensively around the central area, this is worth monitoring. New zones can be added at congestion hotspots more easily than before – though the government’s commitment to being judicious about this provides meaningful reassurance that the charging landscape will not shift dramatically without notice.

Looking Ahead: If Distance-Based Charging Eventually Arrives

It is worth thinking through how distance-based charging would affect car rental economics when it eventually arrives, even if it is not imminent. Under a distance-based model, the total ERP cost per rental would be directly tied to kilometres driven – making high-mileage rentals meaningfully more expensive than low-mileage ones and adding variable cost complexity that fixed-rate rentals today do not carry.

The predictability and simplicity of a fixed monthly rental rate – one that includes ERP costs without per-kilometre variability – would become even more valuable to customers seeking cost certainty in a distance-charging environment. Asia Car Rental will keep customers fully informed as policy developments unfold, and will update rental structures transparently if and when the landscape shifts.

Frequently Asked Questions

1. Do I need to do anything before 1 January 2027 as a Singapore driver?

If you drive a Singapore-registered vehicle, you must ensure your OBU is installed before 1 January 2027. As of September 2026, more than 98% of eligible vehicles are already fitted. If yours is not yet installed, contact LTA immediately – the free installation window was specified in LTA’s notification letter. If you rent a car from Asia Car Rental, the vehicle already has an OBU fitted and you do not need to take any action.

2. What are the blue oval markings appearing on Singapore roads?

From October 2026, LTA is progressively painting blue oval ‘ERP’ symbols on road lanes at the 33 currently active ERP charging locations. These markings replace the overhead gantries as the primary visual indicator that you are entering or passing through an ERP charging zone. A new ‘ERP Charge Zone’ sign is also placed at the start of each zone. Together with the OBU alert inside your vehicle, these give you three layers of advance warning before and ERP charge is applied.

3. Will I be charged more under ERP 2 from 1 January 2027?

No – not at launch. ERP 2 begins with the same zone-based charging framework as the current gantry system. You are charged for passing through designated zones during peak periods, exactly as before. The technology behind the system changes completely, but the charging philosophy and specific zones remain the same on day one. New zones are added more easily under ERP 2, but the government has committed to doing so only at persistent congestion hotspots and with appropriate notice.

4. Why are some gantry frames being kept even after removal?

While the gantry overhead structures and sensor equipment are being removed, some frames at specific locations may be retained and repurposed as mounting structures for Roadside Units (RSUs) that support satellite connectivity for the ERP 2 system. These retained frames serve the new system’s infrastructure needs rather than the old gantry-based charging function. Over time, as alternative mounting options are established, these too may be removed.

5. Is distance-based road charging coming soon?

No. LTA and Ministry of Transport have confirmed clearly that there are no immediate plans for distance-based road pricing. ERP 2 has the technical capability to support it, but the government has said it will allow motorists time to adjust to the new system first, study the impact on high-mileage professional drivers carefully, and provide adequate advance notice if the policy is ever pursued. It is expected to remain several years away at minimum.

6. What does the OBU do that the old IU did not?

The OBU is a significant upgrade. In addition to ERP charge processing, it handles Electronic Parking System carpark payments, checkpoint tolls at Woodlands and Tuas for Singapore-registered vehicles, off-peak car usage licenses, and roadside parking – replacing the need for a separate CashCard and multiple in-car devices. Its touchscreen provides real-time road safety alerts, speed camera notifications, silver zone and school zone reminders, and bus lane indicators. It also allows missed ERP charges to be settled with one button press rather than triggering a criminal offence as under the old system.

7. I drive a Malaysia-registered car into Singapore. What changes for me?

From April 2026, foreign-registered vehicles can install the Singapore OBU at S$158.70 plus installation fees, enabling seamless ERP charge integration. Vehicles without an OBU will pay a flat daily ERP rate of S$3 for motorcycles and S$10 for all other vehicles from 2027. Malaysian taxis are required to install the OBU for tracking and enforcement purposes. If you make regular cross-border trips, installing the OBU is likely more economical than the daily flat rate on frequent multi-day visits.

8. Where will I still encounter ERP charges after 1 January 2027?

From January 2027, ERP charging continues at the same locations active today – concentrated on the AYE, CTE, KPE, and MCE expressways, which represent Singapore’s persistent congestion corridors. These will be renamed ‘road charging zones’ under ERP 2. Your OBU will alert you before you enter any active charging zone, providing advance notice of the upcoming charge wherever you are driving.

Conclusion

The physical disappearance of ERP gantries from Singapore’s roads this October marks the end of a 28-year era and the beginning of a new chapter in how Singapore manages its roads. For many drivers, the gantries have been a fixture so constant they have faded into the background of the daily commute. Their removal, replaced by blue oval road markings and satellite signals invisible to the naked eye, is a quiet but profound shift in the urban landscape.

For everyday motorists, the immediate practical impact is modest. The charging framework remains the same on 1 January 2027. Your OBU handles everything automatically. The familiar look-up-at-the-gantry habit is replaced by looking down at the road surface for the blue oval marking, glancing at the ‘ERP Charge Zone’ sign, and catching the OBU notification on your dashboard. Three clear layers of information in place of one overhead structure.

The longer-term significant of ERP 2 lies in the infrastructure it puts in place: the flexibility to manage congestion with far greater precision, the potential for distance-based charging as a future policy tool when the time is right, and the integration of road pricing into a broader ecosystem of connected in-car services. Singapore has once again positioned itself at the frontier of urban mobility management – consistent with the pioneering role it has played since introducing the world’s first urban congestion pricing scheme in 1975.
