The Minato-Ohashi Bridge is a double-deck type bridge overpassing the main sea-route at the Osaka Port for the exclusive use of vehicles, and has a total length of 980 m and center-span length of 510 m. It connects the central district of Osaka City with the South-port reclaimed land which is under development in the Osaka Bay. The erection work of this bridge was done in three stages. The first stage was the erection of two tower panels on the intermediate piers. The two panel blocks were fabricated at plant and were placed on the piers by a large floating crane. The second stage was the erection of the overhanging- and anchored-spans by the balancing cantilever method accompanied with a traveller crane. The third stage was the erection of the entire block of suspended center beam by winch wire winding up to the anchored beam. Special considerations were given particularly on two points: ensuring the dimensional accuracy of the entire bridge structure and controlling the tightening forces of high- tensile bolts that were used in this bridge in large numbers. /Author/
