A bridging apparatus (1) for an expansion joint (2) between an abuttment (3) and a superstructure (4) includes opposed metal edge profiles (14) in the abuttment and superstructure which are embedded in polymer concrete (10) and have toothed profiles (21) attached to their upper sides to be flush with the abuttment, superstructure and polymer concrete surfaces. The opposed toothed profiles mesh on approaching each other. The edge profiles sealingly hold between them an elastic sealing profile (27). |
