1. The facility was designed as a suspended, cable-stayed single-pylon bridge, 50 meter high, with a beam and slab deck structure, suspended with fan-shaped steel tendons. the bridge has four spans, with the following span lengths:   21.00+35.00+105.00+82.95 m. The P1-P2 and P2-P3 spans, of the length of 21.00 m and 35.00 m respectively, are made of prestressed concrete, while spans No. P3-P4  and P4-P5, length: 105.00 m and 83.08 m, are made of prestressed concrete and suspended on the pylon (the P4 support) with ten cable pairs for both spans. The facility is founded on large-diameter piles, fi: 1200, 8 meter long. The pylon, which is a typical element of cable-stayed bridges, was designed here as a two-arm pylon connected with 3 girts, of a very special shape of reversed shepherd’s stick typical of Polish mountain-dwellers – the symbol of the Beskidy region.

In accordance with the initial technology, the construction of the facility was divided into the following stages:

1. Execution of piles and supports.

2. Pylon execution with the use of slip formwork (16 stages and 17 for the upper arm, respectively). Upper and lower batten places executed together with the arms. Steel structures that fasten tendons in the pylon assembled in the formwork and welded to the reinforcement.

3. Execution of the deck in the continuous part of the facility in the P1-P2-P3-keystone axes (prestressing).

4. Execution of a suspended deck 105 m + 82.95 m (the technology included formworks, concreting, assembly prestressing in 10 sections of the length between 16.4 m and 24.4. m and, then, suspending the executed stage I and moving to the next stage). The stages would commence with a pylon and move towards the P5 abutment and the keystone.

5. Structure compaction and performance of the target prestressing of the facility.

6. Finishing works.
