PROBLEM TO BE SOLVED: To provide an installation method for a viaduct and its installation equipment for improving the competitiveness of cost by simplifying a column. SOLUTION: This installation method comprises a process for erecting a column 8 on one side at a predetermined interval from columns 7, 8 on the other side by stretching a temporary wire 14, stretching a viaduct unit 9 between the columns 7, 8 on the other side and the column 8 on one side, and removing the temporary wire 14 from the column 8 on one side. This process is repeated to connect the other viaduct unit 9 with the viaduct unit 9 and construct the viaduct. Consequently, the temporary wire 14 can be used again, and the viaduct is constituted by erecting the column 8 having a simple shape to reduce manufacturing cost and improve the competitiveness of cost.
