First-class roads connect Lisbon with the chief towns of the districts and with the principal places on the frontier. Second-class roads connect the above named and the cities and principal towns either with each other or with the railway stations and river ports; and lastly, those of the third class join the townships or concelhos with each other or with the preceding roads.
