  • overcrossing on the left-bank junction according to the scheme: 5×21 m
  • left-bank flyover according to the scheme:22.515+21.05+21.37+63.68 m
  • bridge itself according to the scheme: 105.0+6х126.0+105.0 m
  • right-bank flyover according to the scheme: 63.45+5х63.0+63.45 m
  • railway overcrossing according to the scheme: 2х24.0+12.0 m
