A1 motorway (Portugal)
The A 1—Autoestrada do Norte—is the biggest and the most important highway in Portugal. It connects the two largest cities in Portugal, Lisbon and Porto, also passing by some district capitals and industrial zones. Being the most important connection between two major cities, it was designed to be parallel to other roads, like the EN1.
