CPK aims to complete this tunnel construction alongside the launch of the first phase of the new CPK airport.

The project involves three phases, with the recent contract, valued at nearly 147 million zlotys (34 million euros), covering the construction of two chambers for the tunnel boring machine (TBM).

The third phase will include drilling the CPK railway tunnel, with the Retkinia chamber serving as the southwest endpoint, designed as a launch shaft with evacuation platforms, technical facilities, and escape routes.

The recently signed contract encompasses designing plans, specifications, and constructing the launch and receiving chambers, along with managing traffic organization and restoration efforts throughout the project.

Construction of the Retkinia chamber is expected to take 10 months, while the Fabryczna chamber will require approximately 13 months.
