In Spain, the main route connecting the city of Santander on the Atlantic coast of Cantabria with Palencia on the Central Plateau of Meseta Central in the region of Castile and León is the Cantabria-Meseta Motorway, also known as the A67. This toll-free motorway stretches for approximately 200 kilometres through a variety of striking natural landscapes. The route includes 16 tunnels as it crosses mountainous areas, along with several smaller tunnels on its descent towards the plateau. It passes through regions where peaks rise well above 2,000 metres, creating a high risk of snowfall during the winter months. This is particularly true of the Picos de Europa, a spectacular mountain range in the Cantabrian Mountains, known for its glacial lakes and dramatic, steep gorges.
The A67 continues through equally picturesque landscapes, including the upper Ebro basin, before entering the valley and later running alongside another river, the Besaya. On this stretch, the deep gorge carved out by the River Bisueña, a tributary of the Besaya, is crossed by a colossal structure: the Montabliz Viaduct. Supported by piers ranging from 130 to 140 metres in height and reaching a maximum of 150 metres above ground level, it is recognised as the highest viaduct in Spain and the sixth highest in Europe. Continuing through the scenic valley of the River Galerón, still within the Cantabrian region, stands another outstanding engineering accomplishment: the Pujayo Viaduct. Measuring 420 metres in length, it features piers reaching a maximum height of 64 metres.
After leaving the mountains behind, the motorway begins its descent towards the plateau of Castile and León, where it winds gently through fertile farmland and areas of unspoilt countryside. Along the way, it also passes through charming towns, such as Frómista, located along the French Way of St James, and Palencia, the provincial capital, renowned for its rich historical and artistic heritage preserved in its monuments, museums and churches.
Recently, the Cantabria-Meseta Motorway has undergone major modernisation works, including the refurbishment of lighting systems in several tunnels. To address the technical complexity of these environments, the project was entrusted to Disano, which provided tailored lighting solutions based on its extensive experience in developing lighting systems for infrastructure projects.
The choice fell upon Rodio and Astro Q, which represent the very latest in LED technology. Both luminaires have been designed to ensure durability and long-term reliability by using special coatings and LED light sources that are highly resistant to exhaust fumes and other pollutants typically generated by road traffic.
The advanced LED technology also delivers high colour rendering, stable light with low flicker, and optimal horizontal and vertical illuminance levels, helping to ensure safer and more comfortable driving. The precisely engineered optics prevent glare, further enhancing visibility and protecting the eyes.
Moreover, the adoption of these systems significantly reduces energy consumption and maintenance costs, an important consideration when artificial lighting operates continuously, day and night.
From an aesthetic perspective, Disano’s products also combine functionality and design, blending seamlessly into the infrastructure environment. The luminaires feature understated lines and simple, clean shapes.
Thanks to the solutions implemented by Disano, the new tunnel lighting system on this major Spanish motorway meets the highest technical standards, fully addressing the requirements for driver protection, efficiency and visual quality needed to ensure safe and comfortable journeys along these stretches of road.
