In west Ahmedabad, Tata Projects – China Civil Engineering Construction Corporation (TPL-CCECC) JV has completed construction for a crucial bridge on Ahmedabad Metro’s 20.737 km Line-1 (Thaltej – Vastral).
This 165 meter long balanced cantilever (CLC) bridge was cast one segment in-situ at a time over the Sarkhej-Gandhinagar (SG) Highway. Located adjacent to Thaltej Station, this 3-span bridge is about 18 meters high and has a configuration of 45 m + 75 m (central span) + 45 m while connecting piers SP60 (towards Thaltej Station) – SP61 – SP62 – SP63 (towards Doordarshan Kendra Station).
The bridge was designed to be constructed in 26 carefully defined stages, but the sequencing of those stages was not followed. The form traveler used for casting was designed and fabricated by Bridgecon India.
Some snaps shot at different times over the past month:
Similar cantilever bridges exist over railways lines and roads in Delhi, Chennai, Hyderabad, Lucknow and Kochi. A longer one in Nagpur (see construction images) at 231 meters was just completed with trial runs over it starting last Friday.
This summer, TPL-CCECC JV completed constructing Ahmedabad Metro’s 298.20m Sabarmati Bridge in central Ahmedabad – see details and snaps.
