Mostostal Warszawa SA is one of the largest construction companies in Poland.

We would like to extend our best wishes to our Contractors, Partners, and Colleagues for the upcoming Christmas and the New Year.

This day has already gone down in the history of Polish road infrastructure. On December 10, 2025, the TBM “Karpatka” broke through to the North Portal, completing the excavation of the first tunnel tube on the S19 Rzeszów Południe–Babica route. This is an event of exceptional significance – both for the tunneling industry in Poland and for the strategic Via Carpatia corridor, which will connect the north and south of Central and Eastern Europe. The project is being carried out by a consortium of Mostostal Warszawa S.A. and ACCIONA.

The construction of the Opatów bypass along the S74 and DK9 roads has been completed. The project, executed under the “Design and Build” system, was carried out by a consortium of Mostostal Warszawa S.A. and our strategic partner, ACCIONA.

On 10 December 2025, Mostostal Warszawa S.A. signed a contract with the Municipality of Grodziec to design and construct the Social Services Center and the Municipal Cultural Center. The contract value is PLN 29,944,000 net.
