Gotthard road tunnel

Gotthard Massif | Switzerland

The construction project

The Gotthard Road Tunnel, completed in 1980, is showing its age and requires extensive renovation. To maintain the important north-south transport connection through the Swiss Alps during the renovation work, the Federal Roads Office (FEDRO) is building a second tunnel tube, which is expected to be operational from 2030.

After the new tube is completed, the first (old) tunnel tube will be repaired. Both tubes will then be available for traffic from 2033. One of the prerequisites for the expansion was the relocation of the access to the escape and rescue tunnel.

Hodapp Tunnel swing gate (HTD-2) with integrated wicket door:

The Hodapp Tunnel swing gates (HTD-2) are used as lock gates in the access area of ​​the pressurized escape and rescue tunnel. In the event of a fire, the gate must be able to withstand external influences such as heat and smoke in order to prevent the fire from spreading.

In emergencies, the gates must be able to be opened quickly and easily so that a rapid evacuation can take place. The integrated wicket door can be easily opened in an emergency, provided the required pressure equalization is maintained via the pressure equalization flap, and is used to allow people to pass through during daytime operations.

In dangerous situations, people can leave the tunnel tube along the marked escape routes through fire-resistant sliding doors into the escape and rescue route tunnel in order to be evacuated in an orderly manner via the lock.
