Project outline
“Hulanka” is one of the key interchanges in Bielsko-Biała consisting of a five-arm roundabout and a tunnel of the western inner ringroad, which was built by PeBeKa S.A..
The entries to the tunnel are made of concrete portals, while its interior is covered with sidewalk slabs between the walls and half-battered kerbs. The beams are arranged horizontally at approximately 25 cm centres. The structural component receiving loads from the beams is DSD-system steel stringers. The mounting of the reinforcement was carried out successively, ahead of the shuttering and concrete pouring works. The execution of the project entailed the consumption of 9800 m³ of concrete and 1437 tonnes of reinforcement.
Thanks to this project, PeBeKa's portfolio was extended with respect to the construction of both tunnels and road transport facilities.
Greatest challenges
Constructing the facility constituting an integral element of the city's important thoroughfare.
Key moment
Installing the tunnel's reinforcement.
