The Sabarmati Riverfront Development Project’s Phase II includes the construction of a barrage-cum-bridge from the Torrent Powerhouse in the west to Shahibaug at a cost of ₹367 crore.
All expenses for this bridge will be covered by grants from the Gujarat Municipal Finance Board (GMFB).
The barrage within the riverfront project will operate and maintain a rubber barrage based on an automated control system. During water shortages in the city, approximately 10 to 15 days’ worth of water can be sent for purification through the Kotarpur intake well.
The operation and maintenance of the rubber barrage will be based on an automatic control system, which will ensure that the barrage can be deflected without obstructing the flow of the river during floods.
The contract for the rubber-type barrage has been awarded to YOOIL Envirotech Pvt Ltd from South Korea. Rajkamal Builder Infrastructure Pvt Ltd has been tasked with the work related to water storage, road networks, civil works, and street lighting for the city of Ahmedabad.
Key features of the bridge
Footpaths will be provided on both sides of the bridge, along with full connectivity to the main bridge from all four sides via riverfront roads.
A footpath with a tensile roofing structure, 3 metres wide, will be constructed beneath the deck of the main bridge.
The main span of the bridge will feature a 126-metre-long steel arch, with both ends having suspended arch spans of 42 metres. The remaining spans will be made of RCC prestressed girders.
Theme-based decorative lighting will be installed, and a provision for lock gates for water transportation will be made.
