San Gottardo: first diaphragm falls on north side

Context

In brief

• First diaphragm collapsed on the northern side of the Gotthard
• Mechanical milling machine reached the cavern in the disturbance zone
• Milestone celebrated by Uri authorities and USTRA

Key facts

• What: Collapse of the first diaphragm on the northern side of the Gotthard
• When: Wednesday, April 29, 2026
• Where: Göschenen, Canton Uri
• Who: Uri Canton authorities and Federal Roads Office (USTRA)
• Advancement: 14 months of milling machine progress

Today, Wednesday, April 29, 2026, a significant milestone was reached in the construction site for the second tube of the Gotthard road tunnel. Shortly before noon, the first diaphragm collapsed in the excavation on the northern side, on the Göschenen slope. The mechanical milling machine 'Alessandra,' after approximately 14 months of progress, reached the cavern of the so-called 'disturbance zone' north, which had previously been excavated using traditional methods and secured. The milestone was celebrated today by the Uri Canton authorities and the Federal Roads Office (USTRA), which also provided updates on the resumption of excavation in the south, scheduled for mid-May.

Implications for cross-border workers

The completion of the second tube of the Gotthard tunnel will have a significant impact on cross-border workers who daily cross the Italian-Swiss border. The opening of the new tube, scheduled for 2030, will improve traffic flow and reduce travel times, facilitating work commutes and more. Additionally, the increased safety and reliability of the new infrastructure will make cross-border travel easier.

Operational details

Analysis of practical implications

The collapse of the first diaphragm on the northern side of the Gotthard represents a fundamental step towards the completion of the second tube of the road tunnel. This milestone not only improves safety and traffic capacity but also has significant implications for cross-border workers who use this infrastructure daily.

Improved traffic flow

With the opening of the second tube, scheduled for 2030, a significant improvement in traffic flow is expected. This will reduce travel times and queues, facilitating commutes for work and leisure. Cross-border workers will benefit from shorter travel times and greater service reliability.

Reduced waiting times

Currently, cross-border traffic through the Gotthard is subject to restrictions and limitations due to the presence of a single operational tube. The realization of the second tube will increase the tunnel's capacity, reducing waiting times and improving safety. This will be particularly advantageous for cross-border workers who use this artery daily to reach their workplaces in Switzerland.

Greater safety and reliability

The new infrastructure will make cross-border travel easier, ensuring greater safety and reliability. Cross-border workers will benefit from greater peace of mind during their travels, knowing that the tunnel has been designed to ensure maximum safety.

Comparison with other infrastructures

The project of the second tube of the Gotthard is similar to other ongoing infrastructure projects in Switzerland, such as the project of the second tube of the Monte Ceneri. These projects aim to improve the capacity and safety of road infrastructures, facilitating cross-border travel and improving the quality of life of cross-border workers.

Key points

Concrete actions for cross-border workers

The completion of the second tube of the San Gottardo tunnel will have a significant impact on cross-border workers who daily cross the Italian-Swiss border. Here are some concrete actions that cross-border workers can take to prepare for the changes.

Monitor USTRA updates

Cross-border workers should monitor updates provided by the Federal Roads Office (USTRA) to be informed about the opening times and methods of the new tube. This will allow better planning of movements and being prepared for changes.

Plan trips in advance

With the opening of the new tube, an increase in traffic is expected. Cross-border workers should plan their trips in advance to avoid delays and queues. Using navigation tools and real-time information can help optimize travel times.

Use public transport

To reduce the impact of traffic, cross-border workers can consider using public transport. Switzerland offers an excellent network of public transport, which can be a valid alternative to the car, especially during peak periods.

Inform yourself about new regulations

With the opening of the new tube, new regulations and rules may be introduced. Cross-border workers should inform themselves about any changes and adapt to the new provisions to avoid fines and problems during movements.

Use calculation and comparison tools

To best plan their movements, cross-border workers can use calculation and comparison tools such as the travel calculator and the route comparator. These tools can help optimize travel times and choose the most convenient route.
