Ligerz tunnel opens its "doors"
It was a day full of energy and emotion: Children marveled at the creation of a tunnel and were even allowed to drive an excavator; families who turned the event into a shared adventure; residents of the region who were curious to better understand this major infrastructure project and asked exciting questions.
"This day was a real highlight for us: an open exchange with the population and proof of the interest in this project. The trust and recognition we received motivates us to continue our work with passion and commitment," emphasize site manager Eric Liardon and Armand Sharonizadeh, deputy site manager at Implenia for the Ligerz tunnel.
Over 1,800 visitors took the opportunity to take a look at the large construction site
The "Extension of the line between Ligerz and Twann" project
The expansion of the line between La Neuville and Twann will remove the last single-track section of the Lausanne-Biel railroad line. At the heart of the project is the approximately 2.1 km long Ligerz tunnel, which is scheduled to open at the end of 2029.
The project will create the necessary capacity for a regular half-hourly regional service while ensuring smooth freight traffic.
Particular attention is being paid to sustainability: The excavated material will not be transported by truck, but by ship across Lake Biel. In addition, we are using an environmentally friendly, nitrate-free explosive - Hypex Bio - for the blasting, thereby helping to protect people and nature.
