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 under the Arc de Berà, a Roman arch.
The road starts at the Passeig de Josep Carner in Barcelona. It follows the Avinguda del Parallel, 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, then to 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 Then it passes through Castellón de la Plana after which much of the road has been superseded by the Autovía CV-10 and Autovía V-21 to Valencia.
South of Valencia the road is the Autovía V-31 before becoming the N-340 after junction 536 km of the A-7. The road then heads inland with a junction with the Autovía A-35 before crossing the Sierra de Benicadell through Alcoy. The road then branches off along the Rio Torremanzanas towards Alicante. Through traffic now takes the Autovía A-36. The N-340 then passes through Elche and Murcia, where the road is at parts dangerous.[1] after which the road is downgraded and joins the A-7 for several stretches. It goes through Lorca.
At junction 516 km the road branches in two with the N-340A heading west to Tabernas and the Autovía A-92. The main N-340 becomes the A-7 past Almería until Adra where the Autopista is under construction. The N-340 passes along the coast past Motril, Nerja where the A-7 begins again. After Málaga the road heads through Torremolinos and Fuengirola before becoming the A-7 again. The N-340 re-emerges at Marbella and Puerto Banús and follows the coast south to Estepona where it joins the A-7 again to Algeciras past Gibraltar. The Autovía A-381 takes most traffic west to Jerez de la Frontera through the Sierra Blanquilla.
The N-340 passes Tarifa past the Punta Marroquí o de Tarifa. It then passes Vejer de la Frontera and ends at Chiclana de la Frontera and the N-IV. The last section is being upgraded to the Autovía A-48.
