Santa Rosa International Airport (IATA: ETR, ICAO: SERO) (also known as Coronel Artilleria Victor Larrea Airport) is an airport serving Machala, the capital of El Oro Province in Ecuador. Located 20 kilometres (12 mi) south in Santa Rosa, it replaces the closed General Manuel Serrano Airport in Machala, and is designed to handle international flights from Peru. It was built by the Ecuadorean Army Corps of Engineers under the direction of Ecuador's Directorate General of Civil Aviation. This great scale engineering project was led by Maj. Eng. Henry Miranda and Maj. Eng. J.C. Checa.
