Within Galicia are the Autopista AP-9 from Ferrol to Vigo and the Autopista AP-53 (also known as AG-53, because it was initially built by the Xunta de Galicia) from Santiago to Ourense. Additional roads under construction include Autovía A-54 from Santiago de Compostela to Lugo, and Autovía A-56 from Lugo to Ourense. The Xunta de Galicia has built roads connecting comarcal capitals, such as the aforementioned AG-53, Autovía AG-55 connecting A Coruña to Carballo or AG-41 connecting Pontevedra to Sanxenxo.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): The Autopista AP-53 was originally built by whom?
Xunta de Galicia
