General Information

What is the Gotthard Tunnel and where is it located?

The Gotthard Road Tunnel (Gotthardstrassentunnel) is a 16.9-kilometer highway tunnel connecting Göschenen in the canton of Uri (northern portal) with Airolo in the canton of Ticino (southern portal). It runs through the Gotthard massif in the Swiss Alps and serves as one of Europe's most important north-south transit routes, connecting northern Switzerland and Germany with Ticino and Italy.

When was the Gotthard Tunnel built and opened?

Construction began in 1970, and the tunnel officially opened on September 5, 1980. At the time of its opening, it was the longest road tunnel in the world. The project took 10 years to complete and represented a major engineering achievement, providing the first year-round road connection through this section of the Alps.

How long is the Gotthard Tunnel?

The Gotthard Road Tunnel is exactly 16.942 kilometers (10.5 miles) long, making it one of the longest road tunnels in Europe. Under normal traffic conditions without congestion, the transit takes approximately 12-15 minutes at the speed limit of 80 km/h.

Is the Gotthard Tunnel a one-way or two-way tunnel?

The tunnel has a single tube with one lane in each direction, separated by a center line. This bi-directional configuration means vehicles traveling north and south share the same tunnel space, which is why strict speed limits and safety protocols are essential.

Costs and Tolls

Do I need to pay a toll to use the Gotthard Tunnel?

No separate toll is required specifically for the Gotthard Tunnel. However, you must have a valid Swiss highway vignette (Autobahnvignette) to use Swiss motorways, including the approaches to the tunnel. The vignette costs CHF 40 and is valid for 14 months (from December 1 of the previous year through January 31 of the following year).

Where can I buy the Swiss highway vignette?

The vignette is available at:

  • Swiss border crossings (available 24/7 at major entry points)
  • Gas stations throughout Switzerland and in neighboring countries near Swiss borders
  • Online at www.e-vignette.ch (digital e-vignette with 18-day waiting period)
  • Automobile clubs like ADAC (Germany) or TCS (Switzerland)
  • Some post offices in Switzerland

What happens if I drive without a vignette?

Driving on Swiss motorways without a valid vignette results in a fine of CHF 200, plus the mandatory purchase of a vignette (CHF 40). Total cost for this oversight: CHF 240. Swiss police conduct regular checks, particularly near tunnel portals and border crossings.

Is there a daily or weekly vignette option?

No, Switzerland only offers annual vignettes. There are no short-term options for passenger vehicles. The CHF 40 annual vignette is the only option for cars and motorcycles up to 3.5 tons.

Do trucks and commercial vehicles pay differently?

Yes, vehicles over 3.5 tons pay the Heavy Vehicle Fee (HVF/LSVA), a distance-based electronic toll calculated by weight and kilometers driven. This applies to trucks, buses, and large motorhomes exceeding 3.5 tons total weight.

Opening Hours and Closures

Is the Gotthard Tunnel open 24 hours?

Yes, the Gotthard Tunnel operates 24 hours per day, 7 days per week, 365 days per year under normal circumstances. Unlike mountain passes, the tunnel provides year-round access regardless of weather conditions.

When is the tunnel closed for maintenance?

Scheduled maintenance typically occurs overnight, usually Monday through Thursday between 10 PM and 5 AM. These closures are announced 2-3 weeks in advance. During winter months, overnight maintenance is minimized because the alternative Gotthard Pass road is closed due to snow.

How do I find out about planned closures?

Check our traffic information page for current conditions, or consult our specific articles on night closures 2025 and night closures 2026. Official announcements are also published by the Swiss Federal Roads Office (ASTRA).

Can the tunnel close unexpectedly?

Yes, the tunnel may close temporarily due to accidents, vehicle fires, technical issues, or severe weather affecting portal approaches. Such closures are communicated immediately via variable message signs on approach roads, traffic radio, and online traffic information services.

Traffic and Congestion

When is traffic heaviest at the Gotthard Tunnel?

Peak congestion occurs during:

  • Summer weekends: Saturday mornings southbound (vacation traffic to Italy)
  • Sunday evenings: Northbound return traffic
  • Friday evenings: Southbound weekend traffic
  • Holiday periods: Easter, Christmas, Swiss and Italian school vacations
  • Ferragosto (mid-August): Italian holiday creating massive traffic surges

How long are typical waiting times during peak periods?

During summer weekend peaks, waiting times can exceed 2 hours with queues stretching 15+ kilometers. Typical peak Saturday morning waits range from 30-90 minutes. Mid-week and off-peak times usually see minimal to no waiting.

How can I check current traffic conditions?

Our system updates every few minutes with accurate waiting time estimates and congestion information.

What is the best time to travel to avoid traffic?

For southbound summer travel: depart before 7 AM or after 8 PM. For northbound Sunday return: travel before 2 PM or after 9 PM. Mid-week travel (Tuesday-Thursday) offers the smoothest passage year-round.

Alternative Routes

What alternatives exist if the tunnel is congested or closed?

Three main alternatives exist:

Gotthard Pass Road (June-October only): Scenic mountain route adding 20-30 minutes. Closed in winter due to snow. Suitable when tunnel waits exceed 30 minutes.

San Bernardino Tunnel: Year-round alternative via Chur, adding approximately 45 minutes. Rarely congested. Best option during major Gotthard traffic events or winter closures.

Simplon Pass/Tunnel: Suitable for western destinations, significantly longer but avoids Gotthard entirely.

Is the Gotthard Pass road free to use?

Yes, the Gotthard Pass road is a regular cantonal road and does not require a highway vignette. However, it's only open approximately June through October, depending on snow conditions.

How do I decide which alternative to take?

  • Waiting time under 15 minutes: Stay with Gotthard Tunnel
  • Waiting time 15-30 minutes: Monitor trends, consider timing adjustment
  • Waiting time 30-60 minutes: Seriously consider alternatives
  • Waiting time over 60 minutes: Take San Bernardino route
  • Winter months: San Bernardino is the only viable alternative

Safety and Emergency Procedures

What is the speed limit in the tunnel?

The standard speed limit is 80 km/h (50 mph). During heavy traffic or incidents, variable speed limits may reduce this to 60 km/h or lower. Electronic signs display current limits throughout the tunnel.

What should I do if my car breaks down in the tunnel?

  1. Turn on hazard lights immediately
  2. Move to the emergency lane if possible
  3. Do NOT attempt repairs inside the tunnel
  4. Use emergency phones located every 125 meters
  5. Wait for assistance from tunnel personnel
  6. If you must exit the vehicle, stay close to the tunnel wall

What happens in case of a fire?

The tunnel has extensive fire safety systems including emergency exits every 250 meters, ventilation systems to control smoke, and emergency response teams stationed at both portals. If you encounter fire:

  1. If possible, drive past the incident and exit the tunnel
  2. If stopped, turn off engine, leave keys in ignition, exit vehicle
  3. Proceed to nearest emergency exit (marked with green signs)
  4. Use emergency phones to report the situation
  5. Never try to fight a fire yourself unless it's a small fire in your own vehicle

Is mobile phone reception available in the tunnel?

Mobile phone reception is limited inside the tunnel, though coverage has been improving. Emergency phones are available every 125 meters throughout the tunnel. Plan important calls before entering, and rely on emergency phones for roadside assistance.

Are there rest areas near the tunnel?

Yes, facilities are available at:

  • Wassen: 4 km north of Göschenen portal (full service)
  • Airolo: 2 km south of Airolo portal (full service)
  • Erstfeld: Further north on the approach (fuel, food, restrooms)

Use these facilities before entering congested areas, especially when traveling with children.

Vehicle Requirements and Restrictions

Are there vehicle restrictions for the tunnel?

Standard passenger vehicles have no special restrictions. However:

  • Hazardous materials transport requires special authorization
  • Oversized loads need advance permits and escort
  • Bicycles, mopeds, and pedestrians are prohibited
  • Some heavy vehicles face weekend/holiday driving bans

Do I need winter tires or chains?

Winter tires are highly recommended November through March, especially for the approach roads. While the tunnel itself is climate-controlled, the mountain approaches can be snow-covered and icy. Chains may be required on approach roads during severe weather.

Is there a height or weight limit?

The tunnel accommodates standard vehicles with a height clearance of 4.5 meters. Vehicles exceeding 3.5 tons total weight must pay the Heavy Vehicle Fee rather than the standard vignette. Oversized loads require special authorization.

Practical Travel Tips

Should I fill up with fuel before the tunnel?

Yes, always ensure at least half a tank before approaching the tunnel area. Extended waits in traffic can consume more fuel than expected, and running out of fuel inside the tunnel creates dangerous situations. Last convenient fuel stops: Erstfeld (north) and Quinto (south).

How should I prepare for summer travel?

  • Check traffic conditions before departure
  • Ensure air conditioning works (tunnel can reach 30°C)
  • Bring water, snacks, and entertainment for potential waits
  • Plan bathroom stops at rest areas before entering queue
  • Keep vehicle documents accessible for random checks
  • Consider early morning or late evening departure times

Can I stop or park inside the tunnel?

Stopping inside the tunnel is prohibited except in emergencies. There are no rest areas, viewpoints, or parking facilities within the tunnel. Emergency stopping bays exist only for breakdowns or emergencies.

How do I know which portal to use?

  • Göschenen (North Portal): Use when traveling southbound toward Ticino/Italy
  • Airolo (South Portal): Use when traveling northbound toward Central Switzerland/Germany

Our traffic pages show conditions at both portals: Airolo conditions and Göschenen conditions.

Environmental and Future Developments

Is there a second tunnel being built?

A second tube (Sanierungstunnel) is under construction to enable renovation of the original tunnel while maintaining traffic flow. When complete, each tube will carry one-way traffic, significantly improving safety. However, capacity will remain similar to prevent increased trans-Alpine traffic.

Are electric vehicles allowed in the tunnel?

Yes, electric vehicles are fully permitted in the Gotthard Tunnel. Charging stations are available at rest areas near both portals, though not inside the tunnel itself. Plan your charging stops accordingly for longer journeys.

What about the Gotthard Base Tunnel?

The Gotthard Base Tunnel is a separate 57-kilometer railway tunnel opened in 2016, the longest railway tunnel in the world. It serves rail traffic only and is not connected to the road tunnel. Drivers cannot use the rail tunnel.
