Gotthard Tunnel traffic forecast 2026: how to read it
Gotthard Tunnel traffic forecast 2026: peak weekends, typical waiting patterns and how to read the forecast 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 (A2, Göschenen–Airolo) is the busiest Alpine tunnel in Europe. With over 6 million vehicles per year, queues can reach 15 km on peak days — that's over 2 hours of waiting.
This guide provides the complete traffic forecast for 2026: monthly calendar, wait time formula, and optimal travel times to help you avoid Gotthard queues.
How Are Gotthard Traffic Forecasts Calculated?
Gotthard Live combines three data sources:
- Historical traffic data: 5-year patterns by day of week, month and public holidays
- School holiday calendars: Swiss, German, Dutch and Italian holidays — the four nationalities that cause peak congestion
- TCS forecasts: Weekly red/orange/green traffic bulletins
Wait time formula used:
| Queue (km) | Estimated wait |
| 0–2 km | 0–20 min |
| 3–5 km | 33–55 min |
| 6–8 km | 69–92 min |
| 9+ km | 108+ min |
Rule of thumb: every kilometre of queue means roughly 11–12 minutes of waiting.

How to Read TCS Forecasts in Real Time
Gotthard Live aggregates TCS forecasts and displays three alert levels:
- 🔴 Red: queues forecast > 8 km, wait > 90 minutes
- 🟠 Orange: queues 4–8 km, wait 40–90 minutes
- 🟢 Green: < 4 km, wait < 40 minutes
What to Do When There's a Queue
From 7 km of queuing (≈ 80+ min wait), alternatives become worthwhile:
| Alternative | Extra km | Extra time (no queue) | Recommended from |
| San Bernardino (A13) | +28 km | +30 min | Queue > 60 min |
| Gotthard Pass (road) | 0 km | +35 min | Summer, good weather |
| Verlad SBB train | 0 km | +45 min | Families, queue > 90 min |
| Simplon | +95 km | +90 min | Last resort |

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.
