Panval Nadi viaduct Bridge
Panval Nadi viaduct is a 424 m long railway bridge for a single line of broad gauge track, at Ratnagiri in Maharashtra. The bridge superstructure comprises a single-cell, continuous pre-stressed concrete box girder with nine intermediate 40m spans and two end spans of 30 m each. The sub-structure consists of hollow octagonal reinforced concrete piers resting on open foundations.
The tallest of the piers is about 64 m above bed level, which makes Panval Nadi Viaduct the second tallest bridge in Asia. The abutments are spill through.
The bridge was cast in 20 m segments at one end under a covered casting yard. The construction of the pre-stressed box girder was the first use of the incremental launching technique in India.
