Flood tunnel work begins in Lisbon

"In Campolide, almost everything is ready to start excavating the 1st tunnel of the Lisbon General Drainage Plan, which will connect Monsanto to Santa Apolónia", highlighted the CML in a post on X (formerly Twitter), in which it includes some images.

Depois de concluído, começa a escavação do 2º túnel entre Chelas e o Beato com cerca de 1 km. Prevê-se que ambos estejam concluídos em 2025. A obra vai mitigar em cerca de 80% o impacto das cheias em #Lisboa.💧 pic.twitter.com/zOWoRIhqr4

The Lisbon municipality revealed that the space is "the size of a football pitch", and will be built "25 meters underground".

After the completion of this work, "the excavation of the 2nd tunnel between Chelas and Beato" will begin, which will be "around 1 km".

É a obra vai preparar e proteger Lisboa para o futuro.
