Narrative Description of the Project:
All of these studies are framed within the province of Valladolid. The ambit of the study, as shown in the following image, covers the following municipalities: Tudela de Duero, Villabañez, Villavaquerín, Castrillo Tejeriego, Valbuena de Duero, Olivares de Duero, Sardón de Duero, Traspinedo, Quintanilla de Arriba, Quintanilla de Onésimo and La Cistérniga.
The detailed design referred to above corresponds to the so-called South Alternative Duplication Option, approved by the Aranda de Duero (West) – Valladolid study. The Ministry of Public Works took the decision to study the solutions proposed in this preliminary study, through the preparation of a Preliminary Design to analyse the feasibility of a the solution to the North of the N-22, without affecting the valuable vineyards located alongside the road, as happened with the South Alternative-Duplication Option.
For the Preliminary Design of the A-11 between Quintanilla de Arriba and Tudela de Duero, a total of two alternatives are currently being studied:
The Duero North Alternative has a total length of 38 km. Its layout runs separate from the current N-122, north of the River Duero. It starts in Tudela de Duero and ends west of Quintanilla de Arriba.
The typical motorway section consists of 7 m road sections, hard shoulders of 2.5 m (external) and 1.5 m (internal) and a 10 m central reservation. The planned speed limit of the section is 120 km/h.
A total of 5 intersections, 4 viaducts, 11 overpasses and 12 underpasses are proposed. Two viaducts that stand out in particular are the Valle (Bajada del Páramo) at 920 m and the one over the River Duero at 480 m.
The budget for investment in the project is 195 million euros.
The South Alternative-Duplication Option, has a total length of 27 km. The route runs next to the current N-122 with a section of the route to the south of the urban centres of Sardón de Duero and Quintanilla de Onésimo. The section starts to the east of Tudela de Duero, finally reaching Quintanilla de Arriba.
The typical motorway sections consists of 7 m road sections, hard shoulders of 2.5 m (external) and 1.5 m (internal) and a 2 m central reservation. The planned speed limit of the section is 100 km/h.
A total of 2 intersections, 2 viaducts, 11 overpasses and 13 underpasses are proposed.
The investment budget for the project is estimated at 178 million euros.
