The Agencia Nacional de Infraestructura (ANI) has discussed the signing of an addendum to begin studies for the construction of the second carriageway between Catambuco and the Pasto-Rumichaca corridor.

The project aims to improve road safety, reduce travel times, and enhance connectivity in the region. This initiative is part of Colombia's broader infrastructure development efforts and is expected to boost economic growth and regional integration. The studies will evaluate the project's feasibility, design, and environmental impact. This project benefits the entire department of Nariño and directly the inhabitants of the municipalities of Ipiales, Gualmatán, Contadero, Puerres, Funes, Iles, Tangua, Yacuanquer, Imués and Pasto.
