29 August 2017: Bridge inauguration

Conceptual, Preliminary and Detailed Designs
Kota, India
Cable-Stayed Bridges

The Chambal River Highways Bridge was officially inaugurated on 29 August 2017 by India’s Prime Minister, Narendra Modi. Built to carry six lanes of traffic while also respecting the environment and local traditions, this state-of-the-art construction is the first axial suspension cable-stayed bridge to be built in India.

The bridge

Measuring 1,100m overall, the new bridge was designed to improve the road network linking the city of Kota and its one million inhabitants to Jaipur airport. As a result, the journey has been shortened by around an hour, compared to a travel time of more than three hours earlier.

This construction consists of a 700m long main bridge with a 350m cable-stayed section and approach viaducts on either side. The cable-stayed span is designed as a prestressed concrete box girder deck connected with two central concrete pylons by cables in a central plan semi-harp arrangement. Because of its major width, the deck is stiffened by prestressed transverse ribs. It is bordered with acoustic screens to protect the ghavials, a protected species of crocodile, from the noise.

Our mission

SYSTRA worked with Hyundai during the tender. The end client is the National Highways Authority of India. After being selected under competitive bidding, Hyundai hired SYSTRA for the full design work, from preliminary design through to construction design.

Delivered in just 16 months, this entire stage was performed by the design technicians and civil engineers in Paris for the main bridge, while the two access viaducts were designed by the teams from SYSTRA India. In total, more than 50 people from the Group worked on the Chambal River Bridge.

The Group also provided technical support alongside Hyundai during all subsequent stages of construction.
