The excavation work for the new La Quiebra road tunnel link in Colombia is close to completion. The drive is being carried out from both ends of the tunnel and should meet by November 2019. The tunnel construction work will then include completing the lining, building the roadway and carrying out fitting out work. The 8.4km tunnel is costing around US$170 million to build and should be complete by December 2020. The tunnel will form part of the Vias del Nus 4G highway connecting the country’s second city, Medellin, with Colombia’s Caribbean coast.
