A collapse or structural failure of public infrastructure can cause sudden damages: a retaining wall that gives way, debris falling onto the roadway, a section of road that sinks, a barrier or an element of an underpass that detaches. In these cases, the question is not just about the damage suffered: it is necessary to understand which entity had control of the work, what connection exists between the failure and the event, and whether there are external circumstances capable of excluding or reducing liability.
I want to help you distinguish situations where strict custody liability may apply from those where the event depends primarily on an exceptional occurrence, the behavior of a third party, or the conduct of the injured party. We will also examine what elements are needed to file a compensation claim without confusing the formal owner of the infrastructure with the entity that, in practice, was supposed to manage it and keep it safe.
The starting rule is liability for things in custody. Article 2051 of the Civil Code establishes that whoever has custody of a thing is liable for the damages it causes, unless they prove a fortuitous event. A road, bridge, viaduct, retaining wall, equipped slope, or underpass can fall under this rule if the damage derives from their structure, appurtenances, or a defect that manifests itself through a collapse or the detachment of materials. The regulatory reference is Article 2051 of the Civil Code.
However, it is not enough for the damage to occur near a public work. A causal link is required, meaning a concrete connection between the infrastructure and the event. If a fragment of concrete detaches from an overpass and hits a vehicle, the relationship with the work is normally immediate. If instead the damages follow a landslide originating from an external terrain, it must be clarified whether the material fell from a slope, a wall, or a protection system actually included in the custodied infrastructure.
Custody does not coincide with an absolute guarantee against every accident. The injured party must prove the damage and the causal connection with the thing; the custodian, to be released, must prove an external factor capable of interrupting that connection. This criterion is also recalled by the Superior Tribunal of Public Waters in judgment no. 26 of February 18, 2025, which distinguishes the initial burden of the claimant from the proof of the fortuitous event borne by the custodian.
The first practical problem is identifying the actual custodian. For a municipal road, the municipality may play a central role; for a provincial, regional, or state road, other entities may be relevant; for a highway or a section entrusted under concession, the concessionaire or manager may be decisive. It is not sufficient to choose the recipient of the claim based on the location of the accident or a sign: data on the classification of the road, ownership, and management functions attributed for that section are required.
The highway code attributes precise tasks to owning entities. Article 14 links traffic safety to the maintenance, management, and cleaning of roads, technical control of their efficiency, and signage. For concession roads, the powers and duties of the owning entity are exercised by the concessionaire, barring different regulations. You can consult the New Highway Code for the regulatory framework.
Ownership, management, and custody may not belong to the same subject. A work can remain public and, at the same time, be managed by a concessionaire or a person in charge of maintenance. A contract with a company does not solve the problem on its own toward the injured person: what counts is who had effective power of control, intervention, and hazard prevention at the time the damage occurred. For this reason, in complex works, identifying the responsible party requires particular attention.
The evidence must reconstruct a precise fact, not just obvious damage. Photographs and videos of the work, fallen materials, the exact spot, and the conditions of the roadway can show where the debris came from and what obstacle was created. Reports from intervening forces, notifications to the manager, statements from witnesses, and any available images from nearby cameras are also useful.
The timing of the incident can be decisive. A previously reported failure, a moved barrier, ongoing work, intense rainfall, or temporary closure are facts that can modify the reconstruction. They do not automatically demonstrate either the liability of the entity or the fortuitous event, but they help understand whether the hazard came from the structure, whether it was known or knowable, and whether delimitation or warning measures aimed at users existed.
Medical and expense documents serve to prove different items of damage. For personal injuries, certificates, medical reports, prescriptions, and receipts for expenses connected to the event are relevant. For a vehicle, property, or other damaged goods, photographs, estimates, invoices, ownership documents, and a consistent description of the necessary repairs count. If possible, it is prudent to document the asset before repairing it or removing materials, without ever sacrificing personal safety or compliance with authorities' instructions.
The fortuitous event is an external occurrence that breaks the link between the work and the damage. It can consist of a truly exceptional and uncontrollable natural fact, the unpredictable behavior of a third party, or, under certain circumstances, the conduct of the person suffering the damage. It is not enough to state that the collapse was sudden: it must be proven that the external factor had such causal efficacy as to render the custody of the infrastructure irrelevant.
The user's conduct can reduce compensation without always eliminating it. If a person crosses a clearly closed area, overcomes effective barriers, or ignores an immediately recognizable hazard, their behavior can contribute to producing the damage. The consequence is not automatic: it must be verified whether the warning was visible, whether the closure truly concerned that stretch, whether an alternative route existed, and whether the failure was nonetheless unpredictable for transit users.
A hazard warning does not cure every defect of the infrastructure. A generic sign or a notice placed too far away may not be adequate to make a concrete risk perceptible, such as the detachment of debris from an overhead wall. Conversely, clear and timely delimitation can significantly impact causality. The difference lies in the real situation: visibility, lighting conditions, permitted speed, conformation of the place, and actual possibility of avoiding the hazard.
Compensation concerns the proven consequences of the failure. Repair or replacement costs of goods, medical expenses, personal injury, and directly ensuing economic losses can be included, provided they are causally linked to the event and documented. Individual items are not added together in an abstract way: duplication must be avoided, and the value of the damaged asset must be distinguished from the expenses necessary to restore it.
A written claim can immediately clarify the object and recipient of the demand. It is useful to indicate the date, place, dynamics, work involved, alleged damages, and available documents, addressing the subject who appears to be the custodian or even subjects whose position must be clarified. The request does not replace the proof of the causal link and does not transform a technical doubt into certain liability, but it allows the version of facts to be precisely fixed and prompts a response.
It is not advisable to postpone examining time limits. In general, the civil code provides a statute of limitations of five years for compensation from wrongful acts, but the starting point and possible different rules depend on the nature of the act and concrete circumstances. When the collapse has caused serious injuries, involves public works, or presents possible criminal profiles, the time limit must not be calculated by approximation: it must be referred to the actual situation and applicable discipline.
You can address the Municipality only if it turns out to be the custodian of the work or section in question. For roads, bridges, and walls, the Province, Region, State, concessionaire, or another manager may also be competent. The name of the work or its location in the municipal territory is not enough: it is necessary to identify who held management and intervention power at the time of the event.
For custody liability, the starting point is the link between the work and the damage. You must therefore prove that the collapse, failure, or detachment originating from the infrastructure caused the prejudice. The lack of maintenance can be an important element in the reconstruction, but the entity must prove the fortuitous event if it intends to exclude its liability.
No, bad weather does not automatically exclude liability. It must emerge that the natural event, due to intensity and unpredictability, constituted an external cause capable of interrupting the causal link. If the failure also depends on the deteriorated state of a wall, drain, or barrier, the evaluation must consider both causes.
Yes, but the two items must be proved separately. For the vehicle, documents relating to the damage and repairs are needed; for injuries, medical documents and proof of the consequences suffered are required. In both cases, it remains necessary to prove that the damage derives precisely from the collapse, failure, or debris of the infrastructure.
It is not always necessary from the beginning. Photos, reports, medical documents, and estimates can allow an initial reconstruction. However, a technical report becomes particularly useful when the origin of the materials, the stability of the work, the cause of the failure, or the actual cost of restorations is controversial. Its usefulness depends on the technical issue to be clarified, not solely on the value of the damage.
Immediately preserve what allows you to reconstruct the connection between the work and the damage. Collect images of the place and materials, note the date and precise position, keep reports and receipts, and do not lose communications with the entity or manager. If the hazard is still present, the priority remains reporting it to competent bodies and keeping people safe.
