The intervention concerns the consolidation and conservative restoration of Ponte Risorgimento and its access walkways. This architectural work is subject to historical constraints. Given the importance of the structure, diagnostic analyses on the coating and in-depth studies to define the exact colour of the final finish were carried out – in collaboration with the protection bodies.
The intervention focuses particularly on consolidating the internal and external structures of the bridge and improving the pavements by installing basalt slabs, a hard-wearing material. To enable this work, the plans include renovating both the substrate and the waterproofing layer. The operations also include the arrangement of the curbs of the pavement. Finally, at the end of the entire intervention, the road surface will be redeveloped and the joints replaced.
The first phase of the work, which has already been completed, focused on the north side of the bridge. It included the repositioning of all sub-services (such as cables and pipes) under the pavement, the construction of two inspection chambers to allow access to the systems in the event of future interventions without the need to demolish the pavement, and the structural restoration and reconstruction of the plasterwork inside the bridge, together with cleaning of the parapet.
Work is currently underway on the south side, which consists of the internal structural restoration of the bridge and the restoration and cleaning of the parapet plaster.
Work on the pavement and utilities on the south side will resume after the Jubilee Year to avoid negative impacts on traffic. This is because these operations require the occupation of the left lane adjacent to the pavement.
