Roads in the capital are called "street" if they run east–west, and "avenue" if they run north–south. Road numbering starts at the downtown intersection of Avenida Espana/Avenida Cuscatlán and Delgado Arce street. Avenues to the west of this intersection have odd-number names, and to the east they have even-number names. Streets have odd-number names if they are to the north of the intersection, and even-number names if to the south.
