of road upgraded to improve transportation infrastructure

Located some three-and-a-half hours from Libreville, in the heart of the Equatorial forest, the twisting road runs down a hillside and along the Ogowe river.

The Ndjole –Medoumane highway project consists of the renovation and upgrade of Gabon’s main national highway.

Constantly beset by technical and climatic challenges, the works include the installation of drainage, construction of four viaducts and renovation of five bridges.

This is the first project in Africa on which Bouygues Construction subsidiary, DTP Terrassement, has taken responsibility for the project from the design phase.

To meet the needs of the site, a quarry was opened near the village of Medoumane, incorporating a crushing plant, a ready-mix concrete plant and an asphalt mixing plant, along with zones for pre-casting and storing and washing sand.

The project forms part of the country’s regional and economic development plan as the road is a strategic route that is principally used for transporting logs for export.

The project is supporting local employment with 95% of the workers being nationals of Gabon or the Central African Republic.

In a Better Life initiative, Bouygues Construction is committed to the local community through programs to raise awareness of wood recycling (composting, charcoal); distribution of mosquito nets every 6 months to help battle malaria; and the renovation of access roads to schools and water sources to improve safety.
