 In the opening of his speech in the General Council of Senegal , governor Henri de Lamothe proposed that the country should take a loan for infrastructure development . The council agreed on a loan worth five million gold francs , much of the money being for the construction of a metallic bridge between Saint @-@ Louis and Sor . The loan was approved on November 2 , 1892 , by the French president Marie François Sadi Carnot . A French bank , CDG , agreed to give the loan with a low interest of only four percent .
