ONE ARCH AT A TIME

Using 160 concrete semi-arches, French engineers built a 951-ft (290-m) viaduct over the St. Sauveur River in Normandy for linkage to the A13 highway. In its design, the highly statically indeterminate and tensioned structure required the use of three-dimensional modeling with more than 1,500 nodes and a total of 90 deg (1.575 rad) of freedom. To solve all these technical difficulties, the contractor chose to use prefabrication on a separate area because of lack of space close to the Normandy Bridge. The viaduct's arches were constructed from 49-ft (15-m) half-sections, so that they could be transported by road to the worksite just over a mile away. A specially designed truck that allowed for the shape and weight of the components to be moved safely and effectively provided transportation. Once delivered to the site, the semi-arches were positioned at the rate of four sections per day, with the end section fitting into a shell-crosshead previously positioned at the top of the pier on the mobile support devices.
