After casting the first pier on Wardha Road in April, workers from NCC Ltd. last week completed casting the first ever segment for the 7.61 km elevated Reach 1 section of Nagpur Metro’s 19.66 km north-south line! The segment is currently being cured using gunny/hessian bags which will be removed in the coming days to reveal its final look at the Jamtha casting yard. After a couple of months, it will then be erected on-site along with other segments (see: images form Ahmedabad Metro’s construction) and joined together using post-tensioning techniques to form the metro’s viaduct.
