In the construction of road bridges, the use of structures and auxiliary elements as a means to facilitate and carry out their constructive process, and that it can be developed, both from a point of view technical as economic, in the most efficient way possible. The structures and auxiliary elements used in the construction of bridges are very diverse, being able to present different characteristics according to the systems of execution and the singularity of the works. In addition, the constructive techniques are subjected to continuous evolution and updating, incorporating new technological advances in order to improve the constructive processes, and for the application of which the design can be required building of specific ancillary elements. The diversity of existing auxiliary structures and means, and those which may be used in the future, makes it necessary to set up a set of supplementary instructions for the purpose of facilitating and unifying, as far as possible, concerning their project, use, assembly, operation and dismantling of such auxiliary elements for use in the construction of road bridges. The purpose of this order is to approve such supplementary instructions for the purpose cited, and to give priority to the continuous improvement of safety in the works. This provision has been subject to the formalities laid down in Royal Decree 1337/1999 of 31 July on the provision of information in the field of technical standards and regulations and regulations relating to the services of the the information society and Directive 98 /34/EC of the European Parliament and of the Council of 22 June 1998, as amended by Directive 98 /48/EC of 20 July 1998.
