Construction project for the Rumichaca-Pasto corridor in Colombia
In 2016, Prointec, the head of a consortium with another Colombian company, was awarded the contract for the project to build the section of the Rumichaca-Pasto corridor between the start of the road and the town of Pedregal. Ruminchaca is the main border crossing between Colombia and Ecuador, and is located in a cluster of grazing areas. This route serves as a major channel for the exchange of products between the two countries, so the new corridor will significantly improve communications between southeast Colombia and its next-door neighbour.
The section of the corridor developed by Prointec consists of 44 km of a two-lane road, of which 19 km involve the duplication and improvement of the existing road, and 25 km are a new construction. The project includes nine junctions, four changes of direction and around 24,500 m2 of viaduct.
Specifically, Prointec carried out the following works: • Traffic study
• Geological and geotechnical studies
• Geometric design studies
• Climatology, hydrology and drainage
• Earth moving and levelling
• Surfaces and paving
• Structures and walls
• Building and urbanisation project
• Signage, road markings and safety barriers
• Additional works: ITS and lighting
• Service replacement
