The energy absorption device for a bridge comprises a rod 1 connected to the floor (table) by a universal joint 2, and a second concentric tubular element 13 connected by a universal joint 14 to a fixed bridge structure. It comprises a concentric intermediate tubular element 4 which can slide in frets (bars, fretwork) 16 carried by the second element with a very high dissipation of energy, whilst between the first element 1 and the intermediate element 4 is located a stack of woven wire cushions 6 which can be compressed elastically during a first part of the travel between the two elements 1, 13. <IMAGE>
