Within the scope of its internationalisation, AFA, SA has been involved since February 2007, when the first stone was laid, in a joint project with Construtora do Tâmega, S.A., in south Mauritania, 430 km from the capital, Nouakchott.

This project consists of the construction of engineering structures (bridges, culverts and run-off sills) over a distance of approximately 300 km, plus about 160 km of asphalt surfacing. The work is divided into two lots:
- Lot 1 - Kaedi - M'bout (Construtora do Tâmega)
- Lot 2 - M'bout - Gouraye (AFA, S.A)

In regard to Lot 2 (the part belonging to AFA), the work consists of the construction of priority works between M'bout and Selibaby, with a view to making travel possible during the rainy season, and the double bituminous surface between Selibaby and Gouraye over a distance of approximately 43 km. Overall, the intervention of AFA, S.A.consists of the construction of 10 bridges, 74 culverts, 13 run-off sills and 43 Km of double bituminous surfacing.

The goal of this project is to equip this zone with the means of communication needed to avoid the cutting off of the population and guarantee them supplies, as well as enable year-round trade with Malí.
