With the delivery of nearly 700 000 m3 of specialised and high-strength concretes (equivalent to about 110 000 trips of mixer trucks, which if parked in a row would represent travelling almost three times the distance between Medellín and Bogotá) and more than 220 000 tons of cement, Argos participated as a strategic ally in the construction of the La Línea Tunnel, one of the most important infrastructure works in Colombia and now the longest tunnel in Latin America.
This project, about to be inaugurated, has an extension of 8.5 km in length and is made up of three short tunnels, 13.4 km of dual carriageway and five viaducts. All of the above connect to the Central Cordillera between Cajamarca (Tolima) and Calarcá (Quindío), and allow communication between the port of Buenaventura and the centre of the country.
“We are proud to have participated as allies in the construction of this mega-project that represents a great milestone for the infrastructure of our country and Latin America. This was a project that represented great logistical and technical challenges, that at Cementos Argos, we attended with height. We are sure that this strategic interconnection project will contribute enormously to the progress of Colombia and its people. This reflects our commitment to continue contributing to the construction of dreams that promote development and transform lives”. – Tomás Restrepo, Vice President of the Regional Colombia.
In order to contribute to the success of the project, and thinking of delivering tailor-made solutions to its clients, Argos, a cement company of the Argos Group, delivered specialised and high-resistance concretes, of which the following stand out: the cast or pneumatic – ideal for the tunnel lining and slope stabilisation on roads, mines, underground works and dams, and hydraulic concrete – a quick-set product that provides greater resistance and, therefore, extends the useful life of the pavement.
For the production and dispatch of concrete, Argos implemented its plant-on-site model, which made it possible to supply construction in real time and contribute to air quality by reducing the traffic of mixing vehicles. In addition, it developed a plan that guaranteed not only the supply of raw materials, but also compliance with high quality standards and the technical support of the company's experts throughout its construction.
About the Megaobra:
Due to its 8.65 km in length, the project is positioned in the ranking of the 20 longest road tunnels in the world. More than 6000 jobs were created during its construction.
It has 17 connection galleries every 500 m that allow the main tunnel to be connected to the rescue tunnel to guarantee safe evacuation in the event of any contingency.
With the delivery of the first phase of the Line Tunnel and its complementary works, it is estimated that, in total, users will save 20 km of travel between the west and the centre of the country, equivalent to reducing their travel times by 50 minutes. When the work is completely finished, the saving in total travel time will be 1 hour and 20 minutes.
