Interbiak Bizkaia

What Interbiak Bizkaia does

Interbiak Bizkaia S.A.M.P. is a foral public limited company (Sociedad Pública Foral) wholly owned by the Diputación Foral de Bizkaia, the provincial council of Bizkaia in the Basque Country, Spain. The company holds the statutory mandate to manage all toll roads and tunnels in the province, operating the AP-8 motorway (Bizkaia section), the Variante Sur Metropolitana (VSM), the Artxanda tunnels, and the pay-per-use provincial roads N-240, BI-625, A-8/BI-10, N-636, and BI-30. Its core function is the operation, maintenance, and capital development of this provincial network, with all activity governed by its public-ownership structure and overseen through a formal electronic contracting platform with 143 historical contracts on record.

The company runs the Bidesaria integrated digital platform, which unifies toll payment, invoicing, monthly Bizkaia-resident subsidies, discount administration, and free-flow debt settlement, and is interoperable with OBE/Via-T electronic tolling. Field infrastructure consists of FreeFlow control arches performing automatic vehicle classification on every transit, alongside a public electronic contracting platform for procurement. The Pollutant-Capturing Tree, a proprietary air-quality technology deployed in the Artxanda tunnels, extends the asset's scope beyond tolling into environmental management. The organisation is headquartered in Bilbao and operates with 51-100 employees under a model that contracts heavy construction externally.

Revenue is generated through per-transit toll fees on roads and tunnels, distance-based pay-per-use tariffs for heavy goods vehicles, electronic toll collection settled via partner banks, and the administration of public-works construction contracts. The company also administers a recurring monthly subsidy programme for Bizkaia residents. Major capital activity is anchored by the €507 million Lamiako Tunnel project — a 3.9 km sub-Nervión crossing — partially financed by a €200 million EIB loan signed in December 2023. Recognition includes the 2024 International Bridges Congress award for the Bolintxu Viaducts and the 2026 Caminos Euskadi innovation award.
