The works will begin in September and are expected to last for approximately six months. Specifically, they will be in charge of two of the tendered lots:
- The design engineering of the communication project.
- The electrical plant and equipment for the two kilometres that the new route will have.
The project, which is expected to be in service by 2025, also includes the undergrounding of the Pasaia-Antxo station. In addition to improving the service for all passengers in Errenteria, Altza, Herrera and Pasaia, the project seeks to contribute to the redevelopment of the Antxo district.
