Parwan Bridge

Aklera, Rajasthan

Project Overview

The project is part of NH-752 Baran-Aklera Road Section in the state of Rajasthan. It includes two major bridges, first of length 412m on river Parwan and second of lenth 123m on its tributary along with approaches. The bridges are of key importance as they link two regions that are disconnected with each other for 4 months during monsoon period.

Both the bridges features typical 41.25 m span twin cell PSC box girder superstructure with 16m deck that caters to 4 lane of traffic along with footpaths on both side. The piers are of around 15.0m height and rectangular in shape with water cut to cater to high water currents. The shallow open foundations is rested directly on the riverbed rock. Another special feature of the project is the use of Vetiver grass for slope stabilization and erosion protection on the road embankments.
