The project of the Vistula River crossing includes a 1.1 km long twin tube highway tunnel under the Vistula River in Gdansk, Poland and it is the final part of the four-phase Slowackiego (Slovacki) Highway Project. The tubes will be connected by seven cross passages; the 7 cross-passages will be excavated below the water table using the ground freezing method as underground support structure. The ground freezing will be performed with the indirect method, using brine freezing, and the ex*****on of the cross passages works will be done while the TBM is excavating the northern tunnel.
