PURPOSE: A bridge structure is provided to prevent water from leaking to connection gaps of bridge units, facilitate construction, shorten the time for construction, and increase the durability. CONSTITUTION: A bridge structure has plural bridge units(11) with road ways(13) and guard fences(15) and expansion-jointing devices. The bridge structure includes a sealing part installed to a connection gap area of the guard fence; an expansion joint part(31) maintaining airtightness of the connection gap area from the outside; plural reinforcing plates(33a,33b); and fixing members(35) integrally fixing the reinforcing plates and the expansion joint part to each guard fence. The sealing part is upwardly slanted toward the guard fences from the end portions of the expansion-jointing devices. The expansion joint part has a wrinkle part disposed to the connection gap areas of the guard fences for mutual approach and separation. The reinforcing plate is layered on the top of the expansion joint part, interposing the wrinkle part.
