A joint spanning construction for bridges has a sealing body flush with the top edge of the road surface and comprising beading made of resilient rubber material inserted into recesses of open-topped sills. The beading is secured against lifting out by retainer bodies of circular cross-section which are fitted half in the walls of the sill recesses and half in the beading. The sills respectively feature webs, which have approximately parallel sides and which are directed towards the road surface so as to extend into the beading. The sections of beading separated by the webs feature concave recesses on their sides opposite the respective webs, and in each case the outer one of such recesses is engaged by the retainer body concerned.
