The northern terminus of the highway is located in the Macará International Bridge (Piura Region) at the border with Ecuador.

The highway crosses coastal and central Lima, the country's capital.

Once it reaches a roundabout in Santa Anita, the Northern part of the highway stops.

The section between Caquetá (Habich, according to the concessionaire)[1] and Javier Prado avenues is called the Vía de Evitamiento and is licensed to Lima Expresa, from the French group Vinci SA.
