Krakow’s Mistrzejowice Tram Tunnel: Impressive Progress Brings Us Closer To The Finish Line!
The tunnel in the central section of the tram line to Mistrzejowice is the most labour-intensive part of the construction. It will be a key part of the city’s new tram infrastructure, starting from the Chałupnika Street and passing through Młyńskie Roundabout in a semi-cutting, and finally entering a fully enclosed tunnel just before Polsad Roundabout. It will allow the tram to safely pass beneath the city, while minimizing disruption on the surface.
After months of intensive work, we’ve successfully broken through the southern section of the tunnel. With the continuous operation of three Long Arm excavators, our team achieved a daily excavation output of 600 m³, working six days a week, from 6:00 AM to 11:00 PM – a testament to dedication and teamwork.
Thanks to early groundwater management, work proceeded smoothly, and the tunnel has already reached a depth of 14 meters at Młyńska Boczna Street. Simultaneously, temporary bracing of diaphragm walls is underway to prepare the site for a stormwater pumping station four meters below the future track level.
A Major Achievement!
We now have over one kilometer of continuous tunnel, with only a single remaining section left to excavate, on Pilotów Street, near the music school. Excavation on this section is planned to be completed in just two weeks, by December 3, 2025.
The breakthrough was summarized by the construction manager, Wojciech Janosz:
“This is a major milestone for the project. Completing this section of the tunnel is the result of harmonious teamwork among many specialists and represents an impressive technological achievement.”
As we approach the completion date, we will see more and more visible progress. This is especially impressive given the complexity of building in the heart of the city. With each passing day, we get closer to the finish line, and soon the results of this enormous effort will become fully visible.
