Safety on Malta's roads is not only about reckless drivers, speeding, or poor enforcement. It is also about something far more basic: whether the infrastructure itself can be trusted not to fail. Last week's closure of a key tunnel leading to the Three Cities, after stones collapsed from its structure, has therefore struck a deeper nerve. It is one thing to navigate congestion and roadworks; it is quite another to wonder whether the road beneath you or above you - given that flyovers have become common - is structurally sound.

We are fortunate that no one was injured when debris fell onto Triq Għajn Dwieli in Cospicua. The police were right to act swiftly and close the road, and motorists were rightly diverted. But the fact that such a vital artery had to be shut down for 24 hours raises serious questions, especially given the scale of public investment that was poured into this tunnel just a few years ago.

In 2021, Infrastructure Malta launched a €2.2 million restoration project on the Għajn Dwieli tunnel. The agency had said the works were aimed at reinforcing the tunnel's structural integrity and upgrading amenities such as lighting. Within a year, it announced that the shaft tunnel had been upgraded, with deteriorated masonry replaced and measures taken to limit water ingress from the natural watercourses that seep through the mass of rock above it. On paper, this was a comprehensive intervention designed to make the tunnel safer and more durable for years to come.

Yet, only five years later, stones have fallen, forcing the temporary closure of the road. This inevitably leads to an uncomfortable but unavoidable question: what exactly was achieved by that €2.2 million investment? Whatever the explanation, the public has a right to know why a structure that was supposedly reinforced and protected from water damage is now shedding masonry onto a busy road.

The concern is not limited to one tunnel. Malta has spent millions of euros on tunnel restoration projects over recent years, often with the promise of long-term solutions. The St Julian's tunnel is a prominent example. Despite extensive and costly works, it continues to suffer from water leaking through the ceiling. Drivers there routinely pass beneath dripping water, a daily reminder that high expenditure does not always translate into lasting results. When these problems recur so soon after major projects, it erodes public confidence not just in the structures themselves but in the institutions responsible for maintaining them.

There are also inconsistencies in how the recent incident was handled. Parliamentary Secretary for Public Cleanliness Glenn Bedingfield stated that it took "one hour" for the collapsed material to be removed. If that is the case, why did the road remain closed for a full 24 hours? Was the extended closure due to further inspections, concerns about additional collapses, or simply procedural delays? These details matter because they speak directly to whether authorities themselves are confident that the tunnel is safe to reopen.

The timing of the collapse, during a period of heavy winds and rain, adds another layer to the issue. Malta was battered by severe weather last week. If rainfall and water ingress can still trigger falling stones after millions have been spent to prevent exactly that, then the resilience of our infrastructure in the face of increasingly erratic weather must be questioned.

Road safety is about more than traffic accidents. It is about the basic expectation that the ground, bridges and tunnels we use every day will not suddenly fail. When a main route to the Three Cities is closed because rocks have fallen from a recently refurbished tunnel, that expectation is shaken. Authorities owe the public clear answers about what went wrong, what risks remain, and what will be done to ensure that drivers and pedestrians can once again travel these roads without wondering if the next collapse is just a storm away.
