S19 Rzeszów Południe-Babica
The section, which will be built by Mostostal Warszawa and Acciona Construcción, will be one of the most interesting and technologically most difficult infrastructure constructions in Poland. The task involves the construction of a tunnel over two kilometers long. Six flyovers, two viaducts, a collision-free passage along national road No. 19 and a passage under route S19 will also be built on the section.
Mostostal Warszawa and Acciona Construcción will build an underground tunnel over 2 km long
The tunnel will be around 2,100 meters long. It will consist of, among others, from two one-way naves, which will be connected by 12 emergency passages. There will also be one emergency crossing. Each of the individual naves will be 12.4 meters wide.
The maximum depth of work is over 70 meters. On the whole length of the tunnel there will be 32 alarm points, 28 rescue niches, 28 hydrants. The tunnel will be equipped with transverse ventilation. The supply of fresh air will take place from below along the entire length of the tunnel, and the exhaust air will be removed using special portals.
The TBM technology, know-how and equipment to be used in this project will be provided by Acciona. The unique experience gained at construction sites around the world will allow the S19 section to be built efficiently and, considering the scale of the investment, extremely quickly.
