The tunnel starts next to the EXPO2020 site. It will accumulate storm and ground waters from the neighbouring areas and bring it towards the Pumping Station located near the sea. The area is extremely exposed to floods during seasonal rains in November – March.  

The mining started February 2019 and the maximum performance of the TBM reached 40m per day.

Finally, on 10.04.2020 the TBM has completed its 5 km journey and arrived to the CS3 shaft.

So far, only 700 m remaining before the final breakthrough – which is planned to happen in May 2020.
