Abstract
The subject of this article is provisional spans used in cases of ad hoc and temporary reconstruction of damaged or destroyed railway bridges. The general principles of temporary bridge reconstruction are given, as well as the purpose of using these spans and their classification. The following provisional spans were characterised in terms of construction and installation technology: lattice spans (folding and fixed), spans made of steel I-beams, load-relieving structures (bridge type and made of railway rails) and spans made of wooden beams. Attention was drawn to the need to try to use the existing structural elements of the damaged bridge as much as possible.
