ARABIE SAOUDITE: PONT A HAUBANS EN CONSTRUCTION

This article describes the design and construction of the Wadi Laban Cable-Stayed Bridge in Riyadh, Saudi Arabia. This bridge is one of the longest and widest concrete cable-stayed structures in the world. It is 763m long, with a 405m main span and end spans of 179m each. It is 35m wide, and has two 13.95m wide carriageways. Its deck is about 85m above the wadi that it crosses. Its towers have heights of 175m and 167m. Its design and construction combine several areas of engineering and surveying expertise with innovative contracting and construction techniques. Construction began in August 1993, and its completion is expected by the end of 1997. The following stages of construction are described briefly: (1) tower foundations; (2) towers; (3) cast-in-situ deck over each pier; (4) precasting of deck segments (the widest in the world); (5) erection of segments; (6) prefabrication and erection of cable stays; (7) construction of abutments; and (8) closure. The innovative materials and techniques used include: (1) special concrete materials; (2) pre-camber; and (3) self-climbing formworks.
