Feared roundabout at Son Rossinyol is being rebuilt — is Palma facing a year of gridlock?

Key question: Can the announced reconstruction be organized so that the island does not sink into months of traffic jams?

From September, a major reconstruction will begin on the northern edge of the Son Rossinyol business park, a project that is already causing iritated car horns in Palma; related planning has also touched on nearby sections of the ring road such as Ring Road: New Pedestrian Bridges — Safety or Hasty Decision?.

The island council has confirmed the works and set out the interventions in Palma aims to ease congestion: roundabout expansion, FAN access and 13 small roadworks: the roundabout, which is passed by around 46,000 vehicles daily and is considered particularly tricky by many, will be given significantly more space. The diameter is to increase from 55 to 85 meters, a new direct access to Son Sardina will be created, a parking area is planned on the Camino de Passatemps, and land will be prepared for a future municipal road. In addition, the exit from the Camí dels Reis towards Son Espases hospital is to be redesigned so that vehicles no longer have to enter the roundabout.

The math is simple: more space, more capacity, smoother traffic in the long term. But between calculation and reality lie asphalt, construction traffic lights and summer heat. The works are expected to last about a year, so completion is anticipated by the end of 2027. That means a whole traffic season with extra strain — at a time when commuters, delivery traffic and tourists already cause heavy congestion and when numerous other projects are underway Millions for Mallorca's Roads: Many Construction Sites, Few Guarantees.

Critical analysis: What sounds good can become a stress test during the construction phase. A larger roundabout requires construction zones, detours and temporary traffic regulations. If today's direct passage disappears or is reduced to one lane, access to the business park will quickly turn into a backlog. Residents of Son Sardina and users of the Camí dels Reis could be doubly affected: construction traffic plus lost shorter connections.

What is largely missing from the public debate so far are clear details on construction phases, night work, coordination with Son Espases hospital and signage for heavy goods traffic. Who will bring the articulated trucks to their destinations without detours when the usual routes are narrowed? And how will public transport be adapted so buses are not permanently stuck in queues?

An everyday scene from Palma: It's 5 pm, the sun still hangs heavy over the Paseo Marítimo, crates of beer are loaded into delivery vans, and a caravan of rental cars, delivery vehicles and commuters has formed at the roundabout. The air conditioning wheezes, a motorcyclist curses softly, an elderly woman hurries across the central island with shopping bags — and suddenly everything stops. We will see such sequences more often this autumn unless planning is forward-looking.

Concrete solutions can be identified and implemented: first, the site could be divided into clearly delimited phases that each affect only individual access points. Second, as much work as possible should be carried out at night or in the early morning hours to relieve daytime traffic. Third, a park-and-ride should be set up immediately on the planned area at Camino de Passatemps, connected with strengthened bus and shuttle services to Son Sardina and the city center.

Fourth, there must be coordinated communication: digital panels at the approaches, warnings in navigation services and clear detour signs. Fifth, hospital accesses must not fall victim to improvised traffic chaos — a prioritized, lane-specific routing towards Son Espases is necessary. Sixth, a temporary adjustment of delivery windows for businesses in the industrial park is worthwhile so that lorries do not push through during peak hours.

Practical measures that show quick effect: limited construction areas with their own traffic light cycles, temporary one-way streets for local traffic and speed-reduced transition zones for pedestrians. In addition, the island administration should promptly analyze bus routes and offer additional capacity at peak times. All this costs money but saves commuters time and nerves — and reduces the risk of accidents at an already sensitive point; similar reconstruction debates are under way elsewhere on the island, for example at Son Castelló Roundabout at Son Castelló: Reconstruction from 2026 — Relief or Construction Chaos?.

Conclusion: The reconstruction of the roundabout can be a gain for Palma if the project does not only focus on the final solution but also takes the intervening months seriously. Without a stringent construction strategy, coordinated traffic management and a visible relief plan, long queues, frustrated residents and compromised emergency routes are likely. Those who plan now must show that good infrastructure is not only evident after completion, but above all in how well the transition period is managed.

The island has announced the measure, the facts are clear. The question remains: Will prudence arrive with the excavator? Or will we have to get used to a new soundscape of horns, compressed air and construction radio?
