Si th 31 t f M h 2010 th E d h l d thSince the 31st of March 2010, the Eurocodes have replaced the current national codes for the design of construction works, and
bridges in particular. We do not need to give the good example: theirusability has been checked since several years the design loadsusability has been checked since several years, the design loads
cover correctly physical loads and their rules are modern and reliable.
