History

CTB

The Biscay Transport Authority was launched with the goal of building the Bilbao underground and in December, 2000, it celebrated its 25th anniversary deeply involved in work on Line 2 which provides service for the Left Bank of Greater Bilbao.

Also by that time, it managed to come up with CREDITRANS, a step prior to reordering public transport in the territory which will be another one of its most complicated and important challenges.
