Sweden opened the world's first public electrified road, a 2-kilometer conductive rail segment near Arlanda airport called eRoadArlanda, in April 2018. By early 2023, the Swedish Transport Administration (Trafikverket) had recommended against large-scale deployment. The technology that promised to let cars and trucks charge while driving had been judged less cost-effective than stationary charging for battery-electric models.
Germany's eHighway program on a 10-kilometer stretch of the A5 autobahn in Hesse, launched in May 2019, met the same fate. The overhead wire setup was scheduled for dismantling by the end of 2024 after failing to prove economic viability. The Smartroad Gotland wireless charging pilot on a 1.6-kilometer segment concluded its test phase and was decommissioned without plans for permanent installation. Electreon, the Israeli company that ran wireless charging road pilots in Tel Aviv and Detroit, pivoted from open-road dynamic charging to closed-loop commercial applications such as bus depots and ports.
As of March 2025, no government has committed to large-scale national deployment of electrified roads beyond initial test segments. The total global length of operational electrified road open to public traffic is effectively zero.
Two Technical Approaches, One Unproven Economics
Electrified roads divide into two families: contact-based and contactless. Contact-based systems use a physical connection point, either a rail in the road surface or an overhead catenary wire, to transfer electricity directly to the vehicle. eRoadArlanda used a conductive rail buried in the asphalt. A movable arm under the vehicle made contact as it drove. The German eHighway used overhead catenary wires, familiar from trolleybuses and trains, with a pantograph on the truck roof.
Contactless systems, such as the Smartroad Gotland project and Electreon's pilots, use magnetic coils buried under the road surface. A receiver coil on the vehicle picks up the magnetic field and converts it back to electricity. No physical contact is needed. The driver does not have to align the vehicle precisely. But wireless transfer is less efficient than wired. Energy losses are higher, and the system requires expensive power electronics on both the road side and the vehicle side.
Both approaches share a fundamental challenge. The road network must be installed at high density to provide meaningful range extension. A 2-kilometer segment can add only a few kilowatt-hours to a vehicle's battery, even at high power transfer rates. To enable long-distance travel without stopping, electrified roads would need to cover a large fraction of the highway network.
Sweden's Pilot Projects: From First to Last
The eRoadArlanda Conductive Rail
Sweden was the most ambitious early adopter of electrified roads. The eRoadArlanda conductive rail segment, opened in April 2018, was the world's first public electrified road. It was a 2-kilometer stretch near Stockholm's main airport. Trafikverket, the government body overseeing the trials, also backed the Smartroad Gotland project, a 1.6-kilometer wireless charging road on the island of Gotland.
Smartroad Gotland's Wireless Trial
Both projects generated technical data. The conductive rail demonstrated that a vehicle could draw power at highway speeds. The wireless system showed that contactless charging could work in a real road environment. But the economic case never held up. Trafikverket published a report in 2023 concluding that electrified roads are not a cost-effective national strategy compared to stationary charging for battery-electric models.
Trafikverket's 2023 Verdict
The recommendation was decisive. Sweden effectively abandoned national ambitions for large-scale electrified road deployment. The eRoadArlanda segment was removed. Smartroad Gotland was decommissioned after its test phase. No permanent installation followed.
Germany's eHighway: Overhead Wires, No Business Case
The A5 Autobahn Experiment
Germany took a different technical path. The eHighway program, launched on a 10-kilometer stretch of the A5 autobahn in Hesse in May 2019, used overhead catenary wires to power hybrid trucks. Siemens Mobility was the primary technology provider. The system was funded by the Federal Ministry for Economic Affairs and Climate Action (BMWK).
How the System Worked
The idea was to let trucks run on electricity on the highway and switch to diesel or battery power for the first and last miles. A pantograph on the truck roof connected to the overhead wire automatically. The system worked technically. Trucks could draw power at autobahn speeds. But the economics did not.
Why the Business Case Collapsed
Multiple studies estimate the cost of building 1 kilometer of electrified road at between €1 million and €2.5 million, depending on the technology. For overhead catenary, the cost was at the higher end. The setup required wires, masts, substations, and grid connections. It only served trucks equipped with pantographs. No major truck manufacturer committed to producing eHighway-compatible models at scale. The program was terminated. The overhead wire network was scheduled for dismantling by the end of 2024.
The Cost Problem That Killed the Category
Per-Kilometer Infrastructure Costs
The cost per kilometer of electrified road is the central obstacle. Multiple studies put the figure between €1 million and €2.5 million per kilometer, depending on the technology and the road type. Rail-based systems tend to be cheaper than wireless ones, but both are expensive. A 100-kilometer highway corridor would cost between €100 million and €250 million for the road network alone. That does not include the cost of equipping vehicles with receivers, which adds thousands of euros per vehicle.
The Stationary Charging Alternative
Compare that to stationary fast-charging networks. A 350-kilowatt ultra-fast charger costs roughly between €100,000 and €200,000 installed. A highway corridor with charging stations every 50 kilometers might need 10 chargers, costing between €1 million and €2 million total. The cost advantage of stationary charging is massive. And stationary chargers improve every year, getting faster and cheaper. Electrified road networks do not benefit from the same learning curve. It is civil engineering, not consumer electronics.
Trafikverket's Arithmetic
Sweden's Trafikverket made the arithmetic explicit in its 2023 report. Stationary charging for battery-electric models is more cost-effective than electrified roads for any realistic deployment scenario. The conclusion ended Sweden's ambitions and set the tone for the rest of the industry.
No Automaker Commitment, No Ecosystem
The Chicken-and-Egg Problem
Electrified roads face a chicken-and-egg problem. Without cars and trucks that can use the roads, the network is worthless. Without a network, automakers have no reason to build receivers into production models. No major automaker or truck manufacturer has committed to integrating dynamic charging receivers into production vehicles. Not one.
Prototypes, Not Production
The German eHighway program required specially modified trucks. Siemens Mobility supplied the pantographs. But the trucks were prototypes, not production models. No truck maker offered a factory-installed pantograph option. The same problem applied to wireless systems. Electreon's charging pilots required retrofitted vehicles. No automaker has announced a production car with underbody charging coils for dynamic charging.
Why Stationary Charging Scales
Battery-electric cars and trucks with stationary charging have a clear path. Automakers build the vehicles. Charging networks build the stations. The two sides can scale independently. Electrified roads require simultaneous investment in vehicles and road networks, with no guarantee that either side will materialize. The coordination problem proved insurmountable.
What Remains: Closed-Loop Applications and Niche Use
Electreon's Pivot to Depots and Ports
Electrified roads have not disappeared entirely. The technology has retreated to closed-loop applications where the economics work better. Electreon, the Israeli company that conducted wireless charging road pilots in Tel Aviv and later in Detroit, Michigan, pivoted away from open-road dynamic charging. The company now focuses on commercial applications such as bus depots and ports. In a bus depot, a single charging pad can charge multiple buses overnight. The network cost is shared across many vehicles. The route is predictable. The business case is clearer.
Mining and Port Terminals
Some niche applications remain. Mining operations and port terminals use contact-based charging for trucks on fixed routes. The network is privately owned. The vehicles are a captive fleet. The cost per kilometer is high, but the alternative, diesel, is also expensive. These applications do not require public investment or coordination across multiple stakeholders.
The Verdict for Public Roads
For public roads, the verdict is settled. Sweden and Germany, the two most advanced programs, both concluded that electrified roads are not a viable strategy for mass deployment. As of March 2025, no government has committed to large-scale national deployment. The technology that promised to eliminate range anxiety and charging stops has been abandoned as a niche solution.

Frequently Asked Questions
Can you charge an electric car while driving on an electrified road?
Technically yes, but no such road is operational for public use as of March 2025. The two main approaches are contact-based (physical connection via a rail or overhead wire) and contactless (wireless magnetic coils). Both were tested in Sweden and Germany but were abandoned as too expensive compared to stationary charging.
Why did Sweden abandon electrified roads?
Sweden's Trafikverket published a report in 2023 concluding that electrified roads are not a cost-effective national strategy compared to stationary charging for battery-electric models. The cost per kilometer, estimated by multiple studies at €1 million to €2.5 million, could not compete with building fast-charging stations.
Are there any electrified roads in the United States?
Electreon conducted a wireless charging road pilot in Detroit, Michigan. The company later pivoted away from open-road dynamic charging to closed-loop commercial applications like bus depots and ports. The status of the Detroit pilot as of March 2025 is not established in this article.
Do any automakers make cars for electrified roads?
No major automaker or truck manufacturer has committed to integrating dynamic charging receivers into production vehicles. The German eHighway program used specially modified trucks with pantographs, but these were prototypes, not production models.
