The Colombian authorities have inaugurated the 21.9km Ipiales-Guachucal-El Espino highway pavement project crossing the municipalities of Ipiales, Guachucal and El Espino, Nariño department.
The inauguration ceremony was led by the country's vice president Germán Vargas Lleras and road authority Invías' director Carlos García.
"This route is of great importance to the region for it connects Ipiales with the Tumaco port and can be used as an alternative route to the Panamerican highway, which connects to the south of the country and with Ecuador," said Vargas Lleras.
The project's investment was 42bn pesos (US$14.5mn).
The Ipiales-Guachuca-El Espino project is part of the broader so called Contratos Plan, which are ad-hoc agreements signed between the national and local governments to develop, in this case, specific projects in the Nariño department.
During the inauguration ceremony, Vargas Lleras also signed a contract for 5.8km of maintenance work and 1.7km of highway rehabilitation for the leftover stretch of the total 35km of highway.
