Plate Girder Bridge (JSB)
Janson’s plate girder bridges (JSB) were designed for temporary applications, especially in areas with heavy traffic density and where a span of up to 43.5 metres is required.
The bridge sections are transported to the construction site as one piece as possible and subsequently installed and assembled into a complete bridge in minimal building time. The sections can be coupled both in the length and transversally and therefore offer an enormous variety of span options and passage widths. The sections are completely produced from high-quality steel and are equipped with steel bridge decks, which is reinforced with troughs.
