National Route 9 crosses the provincial border and the Industrial Corridor continues up to San Nicolás de los Arroyos, province of Buenos Aires. Route 9 also runs west through Santa Fe and towards Córdoba. In addition, a national highway is being built, ultimately to reach the Córdoba City. To the east, the metropolis communicates with the neighboring Entre Ríos (and from there Uruguay and Brazil) through the Rosario-Victoria Bridge, opened in 2003. Much of the agricultural exports of the north of Argentina go overseas through the ports of the Greater Rosario on the Paraná, the Port of Rosario and Puerto General San Martín being the most important ones. Air traffic in the area is serviced by the Rosario International Airport , located 13 km from the center and partly in lands of the city of Funes.
