The major tributaries of the river are the Malleco and the Laja. The river is Chile's second-longest river (the longest being the Loa River) and the Biobío basin is Chile's third largest watershed, after the Loa and Baker basins. The river is also the widest river in Chile, with an average width of 1 km. In the Metropolitan area of Concepción, the river is crossed by four bridges: Biobío Railroad Bridge (1889), Juan Pablo II Bridge (1973), Llacolén Bridge (2000) and Bicentennial Bridge (2010).
