The utility model relates to a construction structure for rebuilding a railway roadbed into a bridge. The construction structure comprises an existing railway line, a D-shaped auxiliary beam, a hole digging pile, a portal frame pier and a simply-supported T beam. A D-shaped auxiliary beam is used for erecting an existing railway line, and the D-shaped auxiliary beam is supported by a hole digging pile; after the portal frame piers are constructed in the existing railway roadbed, the D-shaped auxiliary beams are supported by the portal frame piers to overhead the existing railway line, and the existing railway roadbed is replaced by the simply-supported T-shaped beams to form the railway simply-supported T-beam bridge. The road-to-bridge structure is simple in design and construction method, operation of the existing railway is not interrupted in the construction process, the bridge has good strength, rigidity and stability after the roadbed is changed, roadbed diseases can be thoroughly treated, the operation
