ABSTRACT
ABSTRACT: The 5.10 km long elevated corridor, which is part of six laning of NH-3, in the state of Maharashtra, India, has standard spans of 30 m with an overall width of 19.20 m. There are few special spans at road crossings and ramp mergers. The deck is an externally strutted segmental type, supported on spherical bearings. The segment assembly and launching was carried out by an over head launching girder. The deck is both longitudinally and transversely prestressed. Expansion joints are provided at every second span, i.e. at every 60 m, to ensure smooth riding surface. The substructure is a single pier, supported by open/pile foundation depending on the type of subsoil stratum available.
