- The project included the restructuring of the Lugones, Paredes and Matalablima link roads
Madrid, 19 October 2023. Lantania, in a joint venture with ASCH Infraestructuras y Servicios, has completed the works to add a third lane to the A-66 dual carriageway in Asturias, between Lugones and Matalablima. The President of the Principality of Asturias, Adrián Barbón, and the acting Minister of Transport, Mobility and Urban Agenda (Mitma), Raquel Sánchez, presided over the inauguration of the new infrastructure on Thursday 19 October, accompanied by the President of Lantania, Federico Ávila, and the company’s General Manager of Infrastructure and Construction, José Alberto Carrasco.
The project, awarded by the General Directorate of Roads to the Lantania-ASCH consortium with a budget of 25 million euros including taxes, involved widening the two lanes of the A-66 dual carriageway along the section known as the Asturian ‘Y’ between the Lugones and Matalablima link roads. The widening was done by constructing a third lane for mixed traffic, light and heavy vehicles, both on the outside and on the central reservation, preserving the platform and readjusting the transversal distribution of the lanes and the hard shoulders.
The project, which covered 4.39 km of road, also included rebuilding the Lugones, Paredes and Matalablima link roads. Collector roads and weaving lanes have been added, improving the level of service of the section, increasing its capacity and thus improving traffic flow and safety in the area.
The widening was done using concrete, followed by the application of a surface course over the entire width of the road to improve safety during rainfall and reduce traffic noise. In addition, acoustic barriers have been installed on the sides to reduce the noise that could reach nearby houses, and complementary works have been carried out to replace the lighting with LED technology. The work was completed with the restoration of the surrounding vegetation, using hydroseeding and coconut netting.
The Asturian ‘Y’, which links Gijón, Oviedo and Avilés, is considered the main artery of communication in the centre of Asturias. One of the most important conditions during the works was to maintain the current traffic on the A-66 with two lanes in each direction, which has daily traffic of approximately 60,000 vehicles/day, which meant that part of the works had to be carried out at night.
