HODARIYAT BRIDGE

HODARIYAT BRIDGE


The Hodariyat Bridge connects the Abu Dhabi southern coastline to the Hodariyat Island coastline. The 1.3 km (4,265 ft) long bridge provides a 29 m (95 ft) vertical clearance for the 170 m (557 ft) wide navigation channel. The superstructure carries six lanes of traffic and two walkways. It consists of a 36.3 m (119 ft) wide single cell precast segmental concrete box girder with stiffening struts inside and outside the box.

The 200 m (656 ft) long main span is supported by a single plane of stay cables within the bridge median. The foundations consist of 1.2 m (3 ft) and 1.5 m (4 ft) diameter drilled shafts socketed into the bedrock. The 55 m (180 ft) long approach spans are built by incremental launching from the abutments, while the main spans are built in balanced cantilever using a beam and winch system.

The approach piers are made of precast segments cast by the long-line method. The pile caps are formed with permanent precast shells supported by the pile casings. Construction started on site in January 2009 following the design-build contract award the previous September. Formal handover took place just 27 months later, in April 2012. Design-build project.
