In short: The Bilbao Metro wasn't an immediate success. Early proposals collapsed in 1925 after funding vanished, and the project was abandoned entirely following the civil war. Decades later, a vision for urban regeneration transformed the city, turning a fragmented railway into a vital, high-capacity transit network.

The foundations of the Bilbao Metro were laid much earlier than its 1995 inauguration. The first serious proposal emerged in the 1920s, intended to link Atxuri station with the western edges of the city. However, the project was rendered infeasible in 1925 when the Banco Español de Crédito withdrew its financial backing. Following the civil war, the metro concept was abandoned for years until new momentum built in the 1970s. This initial failure was due to the withdrawal of support from Banco Español de Crédito. The project remained dormant until the government of Biscay and the Bilbao City Council formed a commission in 1971 to study transport needs. By 1974, the Spanish government had pledged financial assistance to revive the metro project.

The modern network is a complex feat of engineering and political negotiation. While Line 1 and Line 2 were inaugurated in 1995 and 2002 respectively, they were built by taking over existing suburban railway lines, such as the one between San Ignazio and Plentzia, which originally opened in 1887. The system's design for underground stations was awarded to architect Sir Norman Foster in 1988, following an open competition to address the city's growing congestion.

Today, the system spans 51 kilometers across 48 stations, making it the third-busiest metro in Spain, trailing only Madrid and Barcelona. The network is highly integrated, connecting with the Bilbao tram, various commuter rail services like Euskotren Trena and Renfe, and the Bilbao Intermodal bus station. While Line 3 opened in 2017 to serve higher neighborhoods, the network continues to evolve, with ongoing discussions regarding potential extensions to the airport and new connections in areas like Rekalde.
