This 4.1 km (2.5 mi) long viaduct is the first section of the Bangalore, Nelamangala Expressway in India. The 16.4 m (54 ft) wide precast segmental box girder carries four lanes of traffic and is built within the median of the NH4 highway.<\/strong><\/p>\n\n\n\n

Typical spans vary from 28.5 m (93 ft) to 39.4 m (129 ft) and use epoxy joints and external post-tensioning. A special 44 m (144 ft) span was achieved by using cantilever piers in conjunction with a typical 39.4 m (129 ft) span. The substructure consists of cast-in-place piers on bored pile foundations. The viaduct is erected span-by-span with an overhead gantry.<\/p>\n\n\n\n
