Sidi M'Cid Bridge is a 164 m long suspension bridge across the Rhummel River in Constantine, Algeria. It was opened to traffic in April 1912 and until 1929 was the highest bridge in the world at 175 m. The bridge was designed by French engineer Ferdinand Arnodin and links the Casbah to Sidi M'Cid hill. The bridge underwent restoration in 2000 when 12 of its cables were replaced by the Algerian company SAPTA.
