A second loan of 179 million francs for the work was approved on 26 June 1903. On 28 December 1905, the Council of Paris awarded the expansion project to the CMP. The decision was formalized on 23 December 1907. Eventually, a third loan of 40 million francs was authorized on 10 April 1908, but this was not granted until April 1910 due to the associated déclaration d'utilité publique, a process required in France to demonstrate the public benefits of a proposed project.
