AP-66 Toll Probe: Asturias Prosecutor Investigates Full Charges 2026

The AP-66 toll road in Asturias is under scrutiny as the regional prosecutor's office opens a preliminary investigation into whether it is legal to charge full tolls while the highway has been plagued by works and restrictions for nearly two years. The probe could pave the way for thousands of drivers to claim refunds for payments made during a period when the road was far from fully operational.

The AP-66, known as the Huerna highway, connects Asturias with León and currently charges up to €16.20 for the full journey—the highest rate in its history. Drivers have long complained about paying premium prices for a road that has repeatedly failed to deliver the time savings it promises.

What Sparked the Investigation into AP-66 Tolls

The Asturias Prosecutor's Office launched the preliminary investigation after mounting complaints from drivers and consumer groups. The central question is whether the concessionaire can legally charge the full toll when the road has been subject to significant restrictions and closures.

Over the past two years, the AP-66 has faced a series of setbacks. In November 2024, a major landslide near Lena buried two lanes. Since last summer, continuous tunnel renovation works have caused ongoing disruptions. And in late August, a new rockfall in the El Negrón tunnel closed the road completely for nearly 12 hours.

Despite these issues, drivers have continued to pay the full toll for a route that is supposed to be faster and more convenient. The investigation will determine whether the concessionaire's pricing practices comply with the terms of its contract and consumer protection laws.

Why This Matters for Drivers and the Concessionaire

If the prosecutor finds that charging full tolls during prolonged works is illegal, it could set a precedent for similar cases across Spain's toll road network. For drivers, it opens the door to reclaiming money paid for a service that was not fully rendered.

The concessionaire, meanwhile, faces potential legal and financial consequences. The company has argued that tolls are necessary to fund maintenance and improvements, but critics say that charging full price during major disruptions is unfair and possibly unlawful.

The outcome of this investigation could also influence future toll road contracts, pushing for clearer clauses on service levels and compensation when disruptions occur.
