Driving through Switzerland on the way to Italy? Chances are you’ll eventually come face to face with the Gotthard Tunnel. At 16.9 kilometres long, this enormous road tunnel cuts straight through the Swiss Alps between Göschenen and Airolo.
For many drivers, the biggest question isn't how long the tunnel is. It's how much it costs, whether you need a vignette, how bad the traffic can get, and whether there is a better alternative when the queues start building.
I've put together this guide with everything you need to know before using the Gotthard Tunnel, including the cost, Swiss motorway vignette, traffic, driving time, safety, the Gotthard Pass alternative and what you can see on either side.
How Much Does the Gotthard Tunnel Cost?
The Gotthard Tunnel itself does not have a separate toll. If you drive through Switzerland on the A2 motorway, however, you normally need a Swiss motorway vignette. For vehicles up to 3.5 tonnes using the Swiss motorway network, the vignette costs CHF 40.
There is no cheaper one-day or weekend vignette, so even if you are only crossing Switzerland on your way to Italy, the standard CHF 40 charge applies when your route uses the motorway.
You can buy the Swiss vignette as a physical sticker or as an e-vignette. For visitors, the e-vignette is probably the easiest option because it is linked to your vehicle's registration number. It is valid from 1 December of the previous year until 31 January of the following year.
What Is the Gotthard Tunnel?
The Gotthard Road Tunnel is a 16.9-kilometre road tunnel running underneath the Gotthard massif in the Swiss Alps. It connects Göschenen in the canton of Uri with Airolo in Ticino and forms part of the A2 motorway.
The tunnel opened in 1980 and was, at the time, the longest road tunnel in the world. Today it remains one of the most important road connections across the Alps, particularly for traffic travelling between northern Europe and Italy.
The tunnel has a single tube, with traffic travelling in both directions.
How Long Does It Take to Drive Through the Gotthard Tunnel?
The tunnel is 16.9 kilometres long, but you don't need a huge amount of time to drive through it. At the normal maximum speed of 80 km/h, the journey through the tunnel takes around 15 minutes when traffic is moving normally.
The problem is getting into the tunnel when traffic is heavy. During busy travel periods, you can spend considerably longer waiting outside than you will actually spend driving underground.
This is why the distance of the queue matters more than the tunnel's 16.9-kilometre length. A journey that should take 15 minutes can turn into a much longer stop if traffic is backed up on the approach.
If you're planning a long drive to Italy, don't calculate your arrival time as though the Gotthard will always take exactly 15 minutes. Give yourself some extra time, particularly during holiday periods.
Gotthard Tunnel Traffic: How Bad Are the Queues?
Traffic is the biggest problem most drivers have with the Gotthard Tunnel. During the busiest travel days, the queue can stretch for kilometres before you even reach the tunnel.
The worst traffic usually occurs during Swiss and European school holidays, summer weekends, Easter and Pentecost. The direction of travel also makes a big difference.
Heading South to Italy?
If you're driving towards Italy, Friday and Saturday are the days I'd be most careful with, especially during the summer holidays.
Saturday morning can be particularly bad as holiday traffic from northern Europe heads south. The queue normally forms on the northern side, around Göschenen and the approach to the tunnel.
If your schedule allows it, travelling early in the morning or choosing a weekday can make the journey much easier.
Heading North After Your Holiday?
The traffic pattern often reverses when people are heading home.
Sunday afternoon and evening can be very busy, with holiday traffic returning north through Ticino and towards the tunnel at Airolo.
During major holiday weekends, the queue can start building much earlier in the day, so don't assume that leaving your accommodation around lunchtime will mean a quiet journey.
When Is the Gotthard Tunnel Usually Busiest?
As a general rule, be particularly careful with:
- Saturday mornings heading south
- Sunday afternoons and evenings heading north
- Summer school holidays
- Easter and Pentecost weekends
- Major holiday changeover days
These aren't fixed rules, and an accident or breakdown can create a queue on an otherwise quiet day. That's why checking the traffic shortly before you reach the Gotthard is still important.
If you have flexibility, changing your departure by a few hours can be much easier than sitting in a long queue on the A2.
How to Check Gotthard Tunnel Traffic Before You Drive
Checking the traffic before you reach the Gotthard can save you a lot of time.
Swiss traffic services provide current information about the A2, and there are also webcams around the tunnel. These are useful because you can see whether traffic is moving normally or whether a long queue is already forming.
I'd check the traffic shortly before leaving and again during the journey. If you're already seeing a major delay, you still have time to consider the Gotthard Pass or another route.
Once you're sitting in the queue, your choices are much more limited.
When Is the Best Time to Drive Through the Gotthard Tunnel?
If you have some flexibility, I'd aim for early morning or a weekday, especially during the summer holidays.
Saturday mornings heading south and Sunday afternoons heading north are the times I'd be most cautious about.
There is no guaranteed quiet hour, though. An accident or breakdown can change the situation very quickly, so I would always check the traffic before setting off.
Gotthard Tunnel or Gotthard Pass?
The tunnel is the obvious choice if you simply want to get across the Alps. You stay on the A2 and avoid the mountain road.
The Gotthard Pass is completely different. Instead of going underneath the mountains, you climb over them, reaching an altitude of around 2,100 metres. The route offers much better views and, on the southern side, you can drive the famous Tremola road, with its tight hairpin bends and historic cobbled sections.
If the weather is good and you have time, the pass can be far more memorable than spending 15 minutes underground.
There is also a practical reason to consider it: a major tunnel queue. If the Gotthard Tunnel is heavily congested, checking the pass can make sense. But don't assume that leaving the motorway automatically means you'll arrive sooner. The pass is a mountain road, and traffic, weather and road conditions can all affect the journey.
The biggest limitation is the season. The Gotthard Pass is normally closed during the winter because of snow and difficult mountain conditions. Before choosing it as an alternative, check that it is open and suitable for your vehicle and the current weather.
Driving Through the Gotthard Tunnel: What Should You Expect?
Approaching the Gotthard Tunnel from the north is quite an experience. The A2 winds its way through the mountains around Göschenen, with the steep valley walls rising on both sides. Then the road suddenly heads into the mountain and the views disappear.
Inside, there isn't much to see, of course. It's a long, straight tunnel, and for around 15 minutes your view consists mainly of the road, the tunnel walls and the traffic around you.
The speed limit is 80 km/h, and this isn't somewhere you want to start overtaking or changing lanes unnecessarily. Keep your distance from the vehicle in front and pay attention to the signs and traffic around you.
On the other side, the scenery changes again. Coming out at Airolo, you're suddenly back in the mountains and heading into Ticino.
Sixteen kilometres is a long way underground, especially when traffic is moving slowly. By the time you see daylight again, you'll definitely know you've been through a very long tunnel.
What If the Gotthard Tunnel Is Jammed?
If you check the traffic and see a long queue at the Gotthard Tunnel, you don't necessarily have to join it. Depending on where you're coming from and where you're going, there are a few alternatives.
The first option is the Gotthard Pass. When the pass is open and the weather is good, you can leave the A2 and cross the mountains instead of going through the tunnel. The road is much more scenic, but it is also slower and more demanding, so I wouldn't choose it simply because the tunnel has a short delay.
Another possibility is the San Bernardino route via the A13. This can be useful for some journeys, particularly if you're travelling between northern Switzerland and parts of Italy. It isn't a shortcut for everyone, though, so check the complete route rather than assuming it will automatically be faster.
And sometimes the best solution is simply to wait. If the queue is moving and you don't have a suitable alternative, leaving the route can mean adding even more kilometres and mountain roads to your journey.
My own rule of thumb would be simple: for a delay of around an hour, I'd probably stay on the A2. If the estimated delay reaches two hours or more, I'd start looking at the Gotthard Pass or San Bernardino, provided the roads are open and conditions are good.
Can Motorhomes, Caravans and Trucks Use the Gotthard Tunnel?
Yes. Motorhomes, caravans and trucks can use the Gotthard Tunnel, but the road charges are different depending on the vehicle and its weight.
For a motorhome up to 3.5 tonnes, the normal Swiss motorway vignette applies. It costs CHF 40.
If you're towing a caravan or trailer up to 3.5 tonnes, there is an important detail that is easy to miss: the trailer also needs its own Swiss motorway vignette. So a car and caravan can require two vignettes.
For heavier vehicles, the rules change. Motorhomes and caravans over 3.5 tonnes are subject to the Swiss heavy vehicle charge rather than the standard motorway vignette. Foreign-registered heavy motorhomes can pay the lump-sum charge, known as the PSVA, through the Swiss Via system.
Heavy goods vehicles are handled under different heavy-vehicle charging rules, so truck drivers should check the applicable Swiss road charge before entering the country.
For most holidaymakers, the simple version is this:
- Car up to 3.5 tonnes: CHF 40 vignette
- Car + caravan/trailer: the caravan/trailer may need its own vignette
- Motorhome over 3.5 tonnes: different Swiss heavy-vehicle charge
If you're travelling with a larger camper or caravan, don't rely on the standard CHF 40 rule. The weight shown in your vehicle documents determines which Swiss road charge applies.
Gotthard Tunnel in Winter
The Gotthard Tunnel is open throughout the year, so it is the normal route across the Alps during winter.
The road leading to the tunnel can still be affected by snow and ice, though. Conditions can change quickly in the mountains, particularly during heavy snowfall.
The Gotthard Pass is normally closed in winter, so don't count on it as an alternative during the colder months. If you're driving to Italy in winter, check the weather and road conditions before setting off.
Winter tyres and other equipment may also be required depending on the conditions and the current Swiss rules.
Is the Gotthard Tunnel Safe?
Yes. The tunnel has strict safety rules and is continuously monitored.
The speed limit is 80 km/h, and drivers must keep a safe distance from the vehicle in front. Because traffic travels in both directions through the same tunnel tube, following these rules is particularly important.
The tunnel was also extensively upgraded following the serious fire in 2001. Emergency systems, monitoring and fire-safety measures were improved as part of the work.
For drivers, the main thing is simple: keep your distance, follow the speed limit and pay attention to the signs. If there is an incident inside the tunnel, follow the instructions given by the tunnel operators and emergency services.
What Can You See Near the Gotthard Tunnel?
It would be easy to treat the Gotthard as nothing more than something you have to drive through on the way to Italy. But the area around it is worth exploring if you have some extra time.
On the northern side, you can visit Devil's Bridge in the Schöllenen Gorge or continue towards Andermatt. The landscape here is very different from what you'll find further south in Ticino.
On the southern side, you're already in Ticino, with Airolo, the Leventina Valley and the historic Gotthard Pass nearby.
And if you decide to take the pass instead of the tunnel, the Tremola road is one of the highlights. Its old cobbled sections and countless bends make the journey memorable in a way the motorway never will.
If you're travelling purely to get to Italy, you can obviously continue straight through. But if you've got a few hours to spare, this is one part of Switzerland where adding a stop can be well worth it.
