The main highway passing through San Salvador is the CA-1 ([[Pan-American highway]]), which at one point becomes Bulevar Arturo Castellanos. The RN-21 (Bulevar Monseñor Romero) is a major east–west road connecting the cities of Santa Tecla and Antiguo Cuscatlán, finally merging in San Salvador with the [[RN-5 (Autopista Comalapa)|RN-5]] East/West (also known as Bulevar los Próceres), that later turns into the North/South RN-5 heading towards the International Airport. Another major roadway is the RN-4 (Carretera Este Oeste) which runs from San Salvador through Apopa, and subsequently merges with the CA-1 Panamericana.

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.

One particularly heavily traveled road is 49a Avenida Norte, which connects with the RN-5 highway to the airport. An important historical street is Calle Arce, which was closed in order to create a pedestrian-only mall in the historic downtown of San Salvador. Some streets in the city are very narrow with little room for cars to pass, although many streets are wide. Speed limits are {{convert|90|km/h|0|abbr=on}} on highways, {{convert|60|km/h|0|abbr=on}} on main roads, and {{convert|40|km/h|0|abbr=on}} on secondary streets and avenues.
