Rehabilitation of Sidi M'Cid suspension bridge, algeria

The structural rehabilitation of the Sidi M'Cid suspension bridge in Constantine, Algeria, is presented. The bridge, designed by Arnodin in 1908, has a main span of 160 m and a mixed cable-supporting system with a stayed deck portion near the towers. Over time, various components of the bridge had corroded, calling for a structural rehabilitation that included partial replacement of the main suspension system as well as major interventions on both anchorages. Because the bridge spans a canyon 200 m deep, specifically designed equipment was required in order to partially replace the suspension system while maintaining the bridge under full service.
