PROBLEM TO BE SOLVED: To provide a shock absorbing member, simply protecting the periphery of a post in placing concrete or the like under an elevated road, and utilized intact as edge cutting to secure earthquake-resisting performance of a post of the elevated bridge. SOLUTION: This shock absorbing unit for a viaduct includes: a flexible block 11 disposed in the periphery of a post 1 and having plasticity or elasticity; and a surface layer member 1 fitted to the top face of the flexible block, wherein the flexible block is buried to expose the surface layer member 11 on the ground surface. In paving the periphery of the post, the shock absorbing unit for the viaduct serves as a form so that flooring material such as concrete does not closely adhere to the post, whereby the post can secure original earthquake resisting performance without being constrained by the flooring material to prevent breakage of the post itself.
