OHLA has carried out the construction of the Quindío section to complete the Central Cordillera Crossing, the most important road infrastructure in the history of the country. The main objective of this project is to improve the logistics of land transportation of passengers and cargo, since 40% of the country’s merchandise is transported along this road corridor and 18,000 cargo vehicles circulate each month.
Specifically, OHLA has carried out the construction of the Quindío section to complete the Cordillera Central-La Línea Crossing with the execution of five short tunnels, seven viaducts, a road interchange, a toll station and all the open-pit works in the 8 km that make up the corridor, including earthworks, retaining walls, slope stabilization, pavement and signaling.
Constructive challenges
During the project, OHLA’s technical team had to face several construction challenges such as the seismic isolation of the Yarumo Blanco, Macanas, Nogal Cafetero and Robles bridges, which have been developed in a high seismic hazard zone. There were also large differences in length (and stiffness) between the piers of each bridge. From the point of view of road safety, OHLA has opted for the installation, for the first time in Colombia, of the PMH-38 vehicle restraint barrier on the Yarumo Blanco and Nogal Cafetero bridges.
