Highway AP-71 León-Astorga.

León, Castilla y León.

Within civil engineering, it is widely acknowledged that, under normal circumstances, it is only sensible to build a highway if the average daily traffic (ADT) on a certain stretch exceeds 10,000 vehicles. Highway AP-71 from León to Astorga was opened in 2002 and has never reached more than half that figure (its ADT for 2014 was 4,000 vehicles). The concessionary filed for bankruptcy, so the construction cost of €115 million for this 37 km stretch will, most probably, be paid with public money through the rescue of the toll-highways in deficit.
