Kolkata Metro Purple Line Extension Design Revised for Integration
The Kolkata Metro's Purple Line extension is getting a design update to make it stronger and easier to connect with other lines.
The changes involve using different types of pillars for the elevated tracks to support the future link with the North-South Metro.
This is happening because the city is planning to expand its metro system.
The aim is to improve transport from the southern suburbs to the central business district.
The company building the line, RVNL, is updating its plans to include these changes.
The focus is on finishing the 1.6 km section that includes a station near IIM-Calcutta.
Design modifications are underway for the Purple Line extension to IIM-Calcutta.
STUP Consultants recommended replacing single piers with portal piers for viaduct construction.
The changes aim to connect the Purple Line with the Blue Line.
RVNL is revising bidding documents for the 1.6 km Joka to IIM-C section.
The focus is on finalizing contracts for the elevated 1.6 km stretch.
