France – Sanitation Works for Tramway Extension

This project involves the extension of the T1 tramway by 6.4 km to the west, connecting the existing T1 and T2 tramways. The extension will link the current T1 station at 'Asnières-Gennevilliers-les Courtilles' with the future terminus at the intersection of Gabriel Péri Street and Côtes d'Auty Street in Colombes. The sanitation networks along the tramway extension will be affected, requiring several construction operations planned for 2025 to 2027, depending on land acquisition progress.
