Overpass over railway line - Kiewit


The overpass over the Kiewit-Hasselt railway line consists of two bridge decks; one in each travelling direction.
Two bridge deck joints shall be installed for each bridge deck. The joints are of a new type with lower noise emissions than the type that was installed previously.
Two travel lanes will be installed for each bridge half.
A pedestrian lane and a wide bike lane will be installed in both directions. The bike and pedestrian lanes shall be separated from the track through a low construction. This gives the advantage of flexibility for the future. A separate pedestrian bridge will also be contructed.

Some key figures:

  • Precast concrete girders: 4,100 m; 192 pieces
  • Reinforced concrete: 6,100 m³
  • Reinforcing steel: 750,000 kg
  • Surfacing (Paving): 33,500 m²
  • Sewer system: 500 m
