Avinguda Diagonal is the broadest and most important boulevard of Barcelona. It is about 10 km long and it cuts Barcelona in two, diagonally (that is the reason it is called “Avinguda Diagonal”). The boulevard starts on the west side of the city, in Corts and passes across the whole city. It ends in the eastern part of Barcelona, in the district named Sant Marti.
The avenue serves as an important transport artery of Barcelona and numerous tourists pass through it on their way to or from the city. Most of the metro lines and 6 tram lines have stations throughout the avenue, as well as the public buses that come from the airport (for additional information – Public Transportation in Barcelona).
