The tender involves constructing the tunnel from the 鈥淩etkinia鈥� chamber to the 鈥淔abryczna鈥� chamber, along with the infrastructure needed for the tunnel, chambers, and railway line. The tunnel will primarily serve high-speed trains travelling between three major Polish cities: Warsaw, Wroc艂aw, and Pozna艅.

CPK has allocated PLN 2.8 billion (鈧�656 million) gross for the project. The lowest bid was PLN 2.166 billion gross (鈧�506 million), while the highest was PLN 2.797 billion gross (鈧�632 million).

鈥淭his is an exceptionally ambitious undertaking, as the 艁贸d藕 tunnel will have the largest diameter of any underground structure built to date using the TBM method in Poland. It will also be the longest tunnel constructed as a single section,鈥� said Deputy Minister of Infrastructure and CPK Government Commissioner, Maciej Lasek. 

The awarded contractor is expected to complete the project within 46 months of signing the contract, anticipated to take place in the second half of 2025.

The entire section of line 85 between Warsaw and 艁贸d藕 is scheduled to be operational by 2032, coinciding with the opening of the new national airport. Once completed, the train journey between the two cities will be reduced to approximately 40 minutes. 

Tunnel drilling is set to commence in the fourth quarter of 2026 and is expected to be completed by the third quarter of 2028.
