It was then that, without that nobody invited it, it appeared the Societe des Grands Travaux de Marseille and despite being her last to arrive at the bid was to her was granted that the construction of the tunnel of the Havana Bay, despite the usual preferences that existed in Cuba toward American interests. Jose Menendez recommended acceptance of the preliminary draft of the French company, as superior to the Americans from the point of technical view, and also with variants of payment much more advantageous.
The tunnel represented an investment of 28.5 billion pesos, equivalent to $, and they added another 7.5 million for the construction of the Monumental road, which away the tunnel with the white road. The French proposed a business of payment which consisted in that the owners of lands in the East of the city, which no doubt the value of their land would be revalued before the construction of the expressway, through bank loans they would buy the amount certain amount of Cuban sugar which later became at the hands of the French.The Cuban State, one of the big beneficiaries of the work, would not invest a penny in it. The Government would gain lucrative barter of sugar and the same French company would have additional utilities if you speculated with sweet in the world market. Work began with the blessing of the French part.
