PROBLEM TO BE SOLVED: To form a running track for a magnetic levitation railway in which a prestressed concrete vertical girder having low weight can be manufactured because the running track is simplified, is preferable in cost and has small wall thickness. SOLUTION: In the running track for a land traffic route, particularly the running track for the magnetic levitation railway such as a Transrapid having a conventional-member running track support base, which has at least one hollow reinforced prestressed concrete vertical girder and is installed at the upper section of a lower structure built by a cast-in-place concrete type or a conventional-member usage type, and a running track plate (3) crossed and passed on a roadway, projected from both sides of the prestressed concrete vertical girder and manufactured as a member as a separate body, the prestressed concrete vertical girder as prestressed concrete support base pipe (2, 2'), which is flat to the running track plate (3), has a bearing shoulder (4) in an upper section and is manufactured by a centrifugal concrete manufacturing method, is formed.
