DETAIL 03/2001
Forming part of the construction programme for the State Horticultural Show 2000, this pedestrian bridge with a staircase tower was created to link two sections of the site that were separated by a railway line. The structure also overcomes the difference in level between the two end points. The use of native types of wood for the construction reflects the tradition of timber architecture and forestry in southern Baden. A combination of simple detailing and the prefabrication of entire constructional components at works helped to achieve an extremely economical structure. The covered bridge was delivered to site in two pre-­assembled halves and hoisted into position by?a crane. The side trusses are designed as two-span elements with a cantilevered end section. They are supported by two H-shaped steel frames and a foundation at the higher ­level. The 43.5-metre-long trusses are slightly cambered, with an elevation of 15 cm at the crest. As a constructional means of timber ­protection, the outer faces of the bridge are clad in Douglas fir boarding. The boards at eye level are fixed on the splay to allow a continuous view out. In order to enhance the ­impression of lightness, the diagonal tie members consist of steel rods.
