Gotthard Tunnel closures in 2026: what to check before you drive

Gotthard Tunnel closures and roadworks in 2026: night windows, diversions and official sources to check before travel.

The Gotthard is not just a tunnel on a map. It is a timing problem, a weather problem and, on holiday weekends, a patience problem.

The Gotthard Tunnel is open 24 hours a day, 365 days a year — but it stops periodically for mandatory maintenance that keeps it safe for the 6 million vehicles that use it annually. Here is everything you need to know.

Why Does the Tunnel Close?

Every planned closure allows essential work:

• Inspection and repair of concrete lining
• Maintenance of ventilation systems (6 units)
• LED lighting checks and replacement (7,000 lights)
• Fire suppression system testing
• Deep cleaning of roadway and tunnel walls

Types of Closure

Night Closures (most frequent)

• When: Usually weekday nights, 22:00–05:00
• Frequency: Variable, more common in spring and autumn
• Impact: Minimal (low night traffic)
• Best alternative: San Bernardino, Verlad or simply wait

TCS Maintenance Windows (planned)

Longer interventions announced weeks or months in advance via ASTRA and TCS.

Unplanned Closures

Caused by accidents, technical faults or extreme weather. Duration unpredictable — from a few minutes to several hours.

How to Stay Informed

1. Gotthard Live (fastest)

3. TCS Traffic Switzerland

What to Do During a Closure

Planned closure:

1. Plan your trip outside the maintenance window

2. Use San Bernardino as the main alternative (A13, Bellinzona ↔ Splügen)

3. Consider the Verlad — active even during short road tunnel closures

Sudden/unplanned closure:

1. Check Gotthard Live for the estimated reopening time

2. If > 45 min: navigate via San Bernardino

3. If < 30 min: consider waiting at a service area

4. Check before diverting — unplanned closures often reopen sooner than expected

Closure vs. Queue: What's the Difference?

Expert Tips

Summer trips with a fixed hotel booking: choose accommodation with free cancellation near Airolo or Bellinzona. If the tunnel closes unexpectedly you can stop overnight and leave the next day without financial loss.

Statistically safest times: night closures tend to fall Tuesday–Thursday. Friday and Saturday nights usually stay open to avoid blocking weekend traffic.

TCS App: sends push notifications for sudden closures — useful for anyone who uses the Gotthard regularly.

Gotthard Live always shows a coloured banner when a closure is in progress or expected within 7 hours. Always check before you leave. 🚦

Practical advice before you leave

• Night closures need planning before departure.
• Check ASTRA or official sources for works and diversions.
• Do not rely on old social posts or shared screenshots.

Useful planning links

• check Gotthard live traffic
• view the Göschenen and Airolo webcams
• compare Gotthard alternative routes
• read the weekend forecast

FAQ

Where should I check the live situation before leaving?

Use live traffic, webcams and the forecast together. At the Gotthard, the final two hours before arrival often matter most.

Do alternative routes always save time?

No. San Bernardino, Simplon or the Gotthard Pass help only when the queue is longer than the extra driving time.

Are waiting times guaranteed?

No. Treat them as guidance. Weather, incidents, metering and return traffic can change the picture.
