Argos, a cement and ready-mixed concrete company of Grupo Argos, has contributed to an interconnection project, which started more than 20 years ago and began its construction process in 2015. The cement company has delivered approximately 220 000 m3 of ready-mixed concrete (the equivalent of about 37 000 mixer trucks, which, if parked in a row, would represent 1233 times the height of the Eiffel Tower), and more than 8000 t of cement.
During the construction process, this project allowed Argos to carry out research and tests in real time to realise the development of another of its patents. The microcement used injections, a product that, due to its particle size, allows sealing cracks and fissures where conventional cements cannot arrive. The company is a pioneer in the production of this type of cement in Colombia and Latin America.
About the Eastern Tunnel (Túnel de Oriente)
The project will connect the metropolitan area of the Aburrá Valley with the San Nicolás Valley. It contemplates a route of approximately 24 km (between tunnels, viaducts, and road interchanges), and will allow almost 19 000 people to move daily from Medellín to the José María Córdova International Airport in just 18 min.
It is designed on a bidirectional roadway and will allow an average speed between 70 and 80 km/hour. It begins in Medellín at the height of the palms in the Baltimore sector, and ends in Saxony, arriving at the José María Córdova International Airport.
The investment of the project was close to COP1 billion. With 8200 m underground, the tunnel is currently the longest excavated vehicle tunnel in the Americas.
