The Franco-Brazilian Binational Bridge spans the Oyapock River, linking the cities of Oiapoque in Amapá, Brazil and Saint-Georges-de-l'Oyapock in French Guiana, France.

Construction of the bridge was undertaken by a partnership between EGESA and the Consórcio Metropolitano de Transportes - CMT, both of which are headquartered in Brasília.

The Professor Carlos Augusto Bittencourt Foundation - FUNCAB (based in the city of Niterói, Rio de Janeiro) was hired to oversee the environmental engineering of the project, so that the construction of the bridge does not harm the natural environment.

Furthermore, the connection between Route N2 and BR-156 is yet another initiative undertaken under the scope of the Brazilian government's PAC (Growth Acceleration Plan) infrastructure project.

In the words of Walter do Carmo pioneer, entrepreneur and engineer actively involved on the project, "the federal highway BR-156 was planned to establish the terrestrial junction between the Amazon River Basin, south of Macapá and Oyapock River Basin in northern Brazil's border with French Guiana."

Though the Oyapock Bridge was to be inaugurated in early 2012,[14] it remained closed as the road on the Brazilian side was not completely paved.

[4][20] The French Minister of Ecology, Sustainable Development and Energy, Ségolène Royal, was originally due to attend the inauguration ceremony,[21] but in the end was not present.

The official reason for her absence at the inauguration ceremony was that her Brazilian counterpart would not be present, but local media suggested that the actual reason was the various protests she faced during her visit in French Guiana, which led her to cut short her visit in the overseas department and fly back to Paris on 17 March 2017.
