(by the University of Deusto), Deusto, Ibarrekolanda and San Ignacio; after the opening of the metro system this overground track was shut down, although service was maintained between Deusto and the Casco Viejo station operated by Euskotren. The service was finally suspended in 2010 and the remaining Deusto and Universidad stations closed down. The district is served by numerous local Bilbobus lines connecting to elsewhere in the city and particularly to Abando and the city centre. The regional buses Bizkaibus serve several stops across the district, connecting to the main University of the Basque Country campus in Leioa and other cities on the right bank of the estuary. According to the Zorrotzaurre Master Plan, an extension of the Bilbao tram is expected to traverse the new Zorrotzaurre island, with four stations planned. Lehendakari Aguirre Avenue, named after the first Basque president José Antonio Aguirre, is the main avenue traversing the district, connecting the Deusto Bridge area all the way to Elorrieta across Ibarrekolanda and San Ignazio. The regional road BI-604 starts at Deusto, connecting with the Asua valley across mount Artxanda, whereas from Saint Pius X square there are connections to the BI-625 regional road towards east Bilbao and the Artxanda-Ugasco tunnels towards the Bilbao Airport. Deusto Canal The Deusto Canal is the district's main waterway after the estuary itself, separating the Erribera quarter into two sections; the riverside proper and the Zorrotzaurre island. It is an artificial canal whose construction began in 1950, although the original project dates the early 20th century. The canal was intended to relieve maritime traffic in the estuary by serving as docks for the industrial activities that then were common in the Deusto riverside. The canal served its original purpose until 2006, when the construction of the new outer Port of Bilbao was completed. The last ship to depart from the Deusto docks was the vessel Fri River, carrying laminated steel. The original project intended the canal to connect directly Elorrieta with the Euskalduna shipyards, transforming Zorrotzaurre into an artificial island, however the construction was stopped before completion, leaving Zorrotzaurre as a peninsula instead. Following the Zorrotzaurre Master Plan designed by architect Zaha Hadid, a key element in the configuration of Zorrotzaurre and the Deusto riverside as new residential areas, works to finally complete the canal resumed in 2014 and was completed in 2018. Bridges There are four bridges in the district, three crossing
