Improvement works for railway permeability on the Palencia – A Coruña line in O Barco de Valdeorras (Ourense).
A new underpass is constructed beneath the switch leading to the O Barco de Valdeorras Station on the Palencia – A Coruña railway line at k.p. 297/950, connecting Rúa da Rampa and Rúa Ramón y Cajal, near Rúa Xirimil. This new underpass is intended for vehicular traffic, while the existing structure will be repurposed for pedestrian use.
The structure consists of a 10m long, 8 m wide and 3.074 m high reinforced concrete box culvert. The roadway consists of two 3 m wide lanes and 1m wide shoulders on each side.
The project requires the construction of two micropile retaining walls, two reinforced concrete retaining walls, temporary bridge railroad track (maintaining rail service during construction), replacement of the ballast under the switch, reestablishment of the railway systems, tamping and leveling of the track, and improvement of the new roadway and adjacent areas of the affected streets.
