The project, known as Tramvalira, is part of the Interreg POCTEFA European cooperation program. It aims to connect the Alt Urgell region with Sant Julià de Lòria and Escaldes-Engordany. This initial phase will focus on technical, economic, and environmental assessments to provide a sustainable alternative to private vehicle use in the Pyrenees.

Supported by an EU grant of 329,841 euros, the study represents a significant step in regional integration. The Government of Andorra leads the project for the first time in a POCTEFA framework, while the Generalitat de Catalunya will manage the European funding to develop this strategic infrastructure.
