A violent downpour hit the area between the Sorrento Peninsula and the Castellammare district on the morning of 25 September 2026, flooding part of the SS145 Sorrentina and forcing the closure of the Santa Maria di Pozzano tunnel.

According to the Il Mattino report, rainwater and debris washed down from the adjacent slopes onto the SS145, making part of the roadway impracticable. The Santa Maria di Pozzano tunnel was partly flooded and was closed because of accumulated water, mud and debris.

Anas personnel and law-enforcement officers were on site to manage traffic and work toward restoring normal circulation.

Where the closure is

Pozzano is a hamlet of Castellammare di Stabia. The diocesan tourism portal places Santa Maria di Pozzano in that hamlet and gives the sanctuary address as Largo Pozzano, 3, which helps locate the affected tunnel and road section within the Castellammare area.

For readers planning movement between the Sorrento Peninsula side and the Castellammare district, the practical reference point is therefore Pozzano and the SS145 Sorrentina section around the tunnel, rather than the wider municipal road network.

What is known and what is not yet established

What is established from the available reporting:

  • The incident occurred on the morning of 25 September 2026.
  • Flooding, mud and debris affected the SS145 Sorrentina.
  • The Santa Maria di Pozzano tunnel was partly flooded and closed.
  • Anas crews and law enforcement were present at the scene.

What is not established:

  • When the tunnel or the affected road sections reopened.

What to do if you need to travel in the area

Because part of the roadway was reported as impracticable and the tunnel was closed, avoid entering flooded or debris-covered sections and follow directions given by Anas personnel and law-enforcement officers on site.

Before setting out, check for an updated reopening notice, since the available sources do not establish a reopening time. If no updated notice is available, postpone non-essential travel through the affected Pozzano section until normal circulation is confirmed as restored.
