Work is underway on the third stage of Colombia’s Bogota-Villavicencio road project. This 24km project is being carried out under the PPP model by the concession holder, Concesionaria Vial Andina (Coviandina). The project is complex and includes the construction of seven tunnels in all, which have a total length of 10.7km, as well as 21 bridges and overpasses measuring 3.8km in all. Coviandina has bored around 930m of the total tunnel length at present. The tunnel sections driven to date include the 4.5km Buenavista II section and the 200m Bijagual II tunnel. Meanwhile three of the bridges should be complete by the end of this year. Coviandina is itself part of the Colombian financial services company Grupo Aval.
