The entire arch is supported by the wooden falsework. Winds blew two people off of a high falsework, killing both. It took two months to construct the falsework alone. The concrete arch sections were erected using timber falsework. The bridge is usually built on falsework. The release of the falsework will coincide with the tensioning of the arch cables. The bridge was jacked up and the falsework put back in place. Each rib of blocks was erected on a falsework system supported on piles. Once more, the falsework went back in place. Each arch is constructed over a temporary falsework frame, known as a centring. The old piers would still be used, but the falsework was entirely removed. Falsework need to have accurate calculation. After curing and any tenon tensioning, wedges will be removed and forms and falsework disassembled. A formwork carpenter creates the shuttering and falsework used in concrete construction. Like other suspension bridge types, this type often is constructed without falsework.
