The Regional Road Network is excellent in Castellón. The CV-10 transformed into a highway acts as an internal communication axis and bypass of La Vall d'Uixó and Castellón, linking the capital with the Airport in Vilanova d'Alcolea. At its completion it will link with Catalonia through the interland.

The CV-15 highway connects Pobla Tornesa and CV-10 with Teruel, almost at Iglesuela del Cid, crossing the province between the coast and the interland. Another road that perpendicular to the coast follows the course of the river Mijares is the CV-20 from Vila-real to the limit of the province in Puebla de Arenoso. For its part, the CV-12 connects the CV-15 with Morella and the CV-14, this town with the province of Teruel, following the Bergantes course.

The rest of the network is made up of roads in very good condition that bring any municipality in the province closer than 2 hours away.

The railway has its main axis in the Mediterranean corridor, through which the rail connections run both with Valencia, Alicante and Madrid, as well as with Tarragona, Barcelona and Europe. Shortly the High Speed Train will circulate along this same corridor, which will place Castellón less than 4 hours from any destination in Spain.
