along a north -south axis up to recent times along the rivers heading to the ocean. Accordingly, the inland Way of St. James, i.e. the Tunnel Route penetrated the province via Irun and turned south-west along the Oria River towards the provincial limits at the tunnel of San Adrian. This stretch was in operation up to 1765 when the Royal Road moved to the western Deba Valley. A minor St. James route crossed Gipuzkoa east to west along the coast. Currently, the main road cutting through Gipuzkoa largely follows that layout, i.e. the N-1 E-5 from Irun to Donostia and on to Altsasu all along the Oria River for the most part (gateway to Navarre through the pass of Etxegarate). Also, the major Irun-Madrid railway runs close to the river up to its very origin on the slopes of Aizkorri at train stop Otzaurte in Zegama. By 1973 engineering works for the Bilbao-Behobia A-8 E-70 motorway had been completed, with the new road cutting across the valleys east to west and turning into the main axis between Donostia and Bilbao, besides enabling heavy load traffic to access the west and south of Spain as a toll road. The regional railway network Euskotren Trena also follows along the coast from east to west, while it proves impractical for long distance on the grounds of its tortuous layout and as it serves small towns. The railway network reaches the border town Hendaia before it changes to SNCF. Within the Donostialdea region, the San Sebastián Metro provides service. The stretch of the A-15 motorway serving Gipuzkoa and Pamplona opened in 1995 embroiled in controversy under protest and an attack campaign led by ecologists, Basque leftist nationalists and eventually ETA. Conflict resolved after a deal about the definitive layout was struck. In January 2010, following a scheme drawn up by the regional government of Gipuzkoa to improve provisions for the ever-increasing road traffic, the Maltzaga-Urbina AP-1 motorway stretch leading to Gasteiz was completed, providing likewise access to the industrial areas of Arrasate and Bergara, the gateway to Álava by village Landa. AP-1 and N-1 E-5 are connected by a highway east to west from Bergara and Beasain. European traffic to south of Spain avoids Donostia's metropolitan area by means of the southern outer road ring. The AVE high-speed rail is currently under construction, with an Y-type layout and links to the SNCF network in
