They are checking the ground over the Vistula. A subway tunnel is to be built here.

Geological work is underway near the Vistula River for the planned fourth metro line in Warsaw. These tests are crucial for assessing soil conditions and ensuring safe construction. The line will connect Białołęka to Wilanów, spanning over 26 kilometers with 23 stations. The project is currently at its halfway point, with completion expected by 2027. The construction is projected to start in the 2030s, aiming for completion by 2044, with high passenger traffic anticipated at key stations.
