road in Spain
The N-340 is a major highway in Spain. It is over 1,000 km long starting south of Barcelona and running predominantly along the coast to Chiclana de la Frontera and the N-IV to Cádiz. In many places the road has now been by-passed by the Autovía A-7 and Autopista AP-7.
It follows the former Roman road Via Augusta, that was one of the main roads of Hispania. The N-340 route passes the Arc de Berà, a Roman arch.
The road starts at the Passeig de Josep Carner in Barcelona. It follows the Avinguda del Paral·lel, Plaça d'Espanya, Carrer de Sants and Carretera de Collblanc before becoming the Carretera de Cadiz a Barcelona and heading through a series of suburbs and industrial areas.
The road crosses the Llobregat valley with a junction with the Autovía A-2 and Autovía B-24, it heads through the Garraf Massif to Vilafranca del Penedès. It then heads along the coast to Tarragona, changing to the A7 until Cambrils, then crossing the River Ebro (delta) and on to Peníscola. Then it passes through Castellón de la Plana after which much of the road has been superseded by the Autovía CV-10 and Autovía V-21 to Valencia.
