Overpass 403 on the A1


The specificity of the project:

The structure was aimed at a impact-free routing of car traffic over the Mała Panew river, DP 2335S district road and an animal migration route.
  • Theoretical span: Lt = 35.0 + 3 × 50.0 + 35.0 = 220.0 m, 
  • Length of the structure: 221.2 m, 
  • Width of the structure: 38.5 m. 
The load-bearing structure was designed as a post tensioned beam structure based on reinforced concrete pillars and reinforced concrete abutments. Two separate load-bearing structures for each direction of traffic are five-span structures with 3 main beams made of prestressed concrete.
