First Girder Placed for Nagpur Metro’s North-South Line

Last week, a crew from NCC Ltd. successfully placed the 1st girder for Nagpur Metro’s 19.658 km north-south line! This 24.3 m long pre-stressed girder along with 3 other girders weighing 55 tonnes each were placed between the upcoming Khapri and New Airport stations where the line will primarily run at-grade for 4.5 km barring 3 locations where it’ll run over local roads and the Container Corporation of India (CONCOR)’s railway siding line.

These particular girders were placed for the CONCOR siding section whose design was given a final approval by the Airports Authority of India (AAI) in October 2015.
