A raceway bridge assembly is provided for carrying wires or cables over an intersecting raceway or other object without interfering with the intersecting raceway. The raceway bridge assembly includes a pair of opposing bridge fittings and a connecting raceway section extending between the raceway fittings. The bridge fittings have a first open end lying in a first plane and a second open end lying in a second plane spaced above said first open end. The bridge fittings have side walls that are coupled to a cover of a raceway section. A top wall is removably coupled to an upper edge of the sidewalls of the bridge fitting and is coupled to the connecting raceway section.
