Arbitration Tribunal Orders the State to Pay the A8 Operator About 55 Million Euros Over Tolls on the Former SCUT Motorways
A tribunal has ordered the State to pay Autoestradas do Atlântico about 55 million euros for traffic lost when tolls came to the former SCUT motorways. The government may use it to negotiate a longer A8 contract.
An arbitration tribunal has ordered the Portuguese State to pay about 55 million euros to Autoestradas do Atlântico (AEA), the private company that runs the A8 and A15 motorways, to compensate it for traffic it says it lost when tolls were brought in on nearby motorways that used to be free. Jornal de Negócios reported the ruling on the evening of 9 November. The money is public money, and Negócios reports that the government intends to use the decision to negotiate a longer contract for the company rather than simply write a cheque.
What the A8 is
The A8 is the main motorway north out of Lisbon through the Oeste (West) region, running from Olival de Basto on the edge of Lisbon to Leiria South. Together with the A15 between Arnóia and Santarém, it makes up 170 kilometres run by AEA under a contract with the State that, according to the company's 2025 annual report, was signed on 21 December 1998 and ends on 21 December 2028. Drivers on the A8 have always paid tolls; AEA collected 105.2 million euros in toll income in 2025 and reported a net profit of 48.9 million euros.
Why the State owes money
The claim goes back to the SCUT motorways. SCUT stands for "sem custos para o utilizador", meaning no cost to the user: the State paid the operators a "shadow toll" per vehicle, and drivers paid nothing. Tolls were introduced on the Costa de Prata SCUT in 2010, and on the Beiras Litoral e Alta SCUT in 2011. AEA argued that the new tolls, which affected the Porto to Lisbon corridor, hit traffic on its own motorway.
Under concession contracts, a State decision that damages the operator's business can give it the right to a "reequilíbrio financeiro" (a financial rebalancing). According to Negócios, the 55 million euros covers the impact of the tolls up to 2028, when the contract runs out. In the 2022 State accounts, as reported by ECO, AEA's claim on this point stood at 73.2 million euros. AEA's own report says the hearing in its case over the former SCUT tolls took place in December 2025 and covered their impact from 2014.
It is the second award on the same grievance. In 2016, Observador reported that an earlier tribunal had given AEA 28.9 million euros for revenue lost between October 2010 and December 2013, against a claim of 530.4 million.
What it means for you
- Taxpayers pay. Compensation under road concession contracts is a cost to the State budget.
- A longer contract is on the table. Negócios reports the ruling will be used to negotiate extending the concession by two to three years beyond 2028, giving the government time to decide how it will run motorways as the current contracts expire. A8 drivers would keep paying tolls to AEA for longer.
- It is not the only bill. AEA's annual report says a separate tribunal ordered the State in November 2025 to pay 70.5 million euros for the impact of the Covid-19 pandemic. The State and the Public Prosecutor's Office appealed that award to the Constitutional Court in January 2026.
Whether the State will challenge the new award has not been reported. Separately, motorway tolls are expected to rise again in January; we set out how the October inflation figure points to next year's toll increase.
