Length: 240 meters
Maximum height: 20 meters
Main girder cross-section: 1.80 meters
Main girder wall-thickness: 40 - 90 mm
Diagonals cross-section: 60 - 80 mm
Diagonals wall-thickness: 12 - 30 cm
Maximum compressive force: 300 MN
Tensile force (given negative head): 50 MN
Connection with hinge: - end-diagonal

- tailpiece
Camber: 8 cm
The trusses were constructed with a camber of 500 mm. After removal of the supports a camber of 80 mm remained.
