Project Phases

  • In its initial phase, work will be undertaken to improve the A-8 link road at Portugalete-Ortuella, Santurtzi Santurtzi-Puerto that will join the new infrastructure. A new 12-km road, 7 km of which consists of tunnels, will be built between Trapagaran Venta Alta. There will be a slip road to the Kadagua Corridor at Alonsotegi a link road to the Bilbao Bypass at Larraskitu.
  • The second stage will involve work on the 11-km Venta Alta Kortederra section, with more than 5 km running through tunnels, with a link road to the current A8 motorway at Urgoti-El Gallo at Kortederra (Amorebieta). There are also plans to improve the La Arena (Zierbena) link road on the current A-8 to build a third lane between La Arena Abanto.
  • The last phase of the VSM envisages building the bypass between San Fuentes Trapagaran by means of a new infrastructure to the south of the current A8 the towns of Ortuella Trapagaran. This measure, which will be undertaken according to mobility needs, will involve an alternative infrastructure to the current one.
