Abstract
A separable bridge, particularly useful for military purposes, having bridge modules which can be coupled together and whose roadway elements, diagonal elements and lower chords form a vertically adjustable framework. The lower chords of the bridge modules are shorter than the roadway element of that bridge module, and the diagonal elements are fastened to ends of the lower chords. The roadway elements have a plurality of fastening points for the diagonal elements and the lower chords. These fastening points are located at different distances from an end of the roadway element. The roadway element, the lower chords and the diagonal elements have constant lengths.
