Colombia: Cementos Argos Colombia supplied around 220,000m3 of concrete and over 8000t of cement for the constriction of the Oriente Tunnel. The road infrastructure project near Medellín in Antioquia is scheduled to be commissioned in mid-August 2019. Work on the project started in 2015. The tunnel had an investment of around US$300m and it will be the longest operational road tunnel in South America when it opens.
