For 2018-2020, the commune has applied for a government grant in order to engage, with the help of public and private partners; in the further restoration of another 13 arches at a cost of 280,000 Euros before tax:
- In 2018 : restoration of arches 38 to 43
- In 2020 : restoration of arches 44 to 50
As in 2016, the works will centre on consolidating the existing structure with new materials and lime mortar, restoration of the bases of the piers to protect them from erosion, and the adding of a patina better to distinguish the restored parts from the original.
On 16 September 2017, during the European Heritage Days, the commune of Chaponost officially launched a second campaign of seeking sponsorship from individuals and businesses thanks to the signature of a new partnership agreement with the Heritage Foundation.
