Tunel de la Risa, which started construction in 1933 and began operation in 1967, is the railway network with the largest circulation in Spain. Its renovation is taking place from July until October 2019, transforming early 20th century infrastructure into a modern facility with the safest transportation technology.
CEMEX supplies 30,000 cubic meters of concrete, including high-strength concrete and fiber, to meet the needs of the 7-kilometer project. The company made continuous material deliveries day and night, seven days a week, according to the contractor’s requirements and project deadlines.
Due to the difficulty of maneuvering inside the tunnel, thorough and calculated logistics of the tunnel’s entrances and exits was designed to achieve constant delivery. Additionally, in some sections, concrete was pumped from outside the Paseo de la Castellana in very precise coordination with the contractor’s work to achieve continuous supply without affecting traffic on the surface, which is one of the main transportation channels of the country’s capital.
