Asia Book of Records and India Book of Records have recognised Nagpur metro rail project for building the longest double-decker viaduct.
This project has led to savings on land acquisition and construction costs and also reduced the travel time to the city’s airport.
The Nagpur metro rail project in Maharashtra has set a new record for building the longest double-decker viaduct with an elevated highway, and Metro Rail supported on a single-column pier.
Asia Book of Records and India Book of Records have recognised this engineering feat. They have also recognised another record of constructing three metro stations on a double-decker viaduct.
“Another World Record in the bag! Heartiest Congratulations to Team Maha Metro and Team NHAI on achieving the world record in Nagpur,” Union Minister Nitin Gadkari said.
This 3.1 Km long double-decker viaduct was built jointly on Nagpur’s Wadha road by Maha Metro and NHAI.
This double-decker viaduct made possible a three-layered transport corridor with the first layer occupied by pre-existing highway, the second layer by a flyover highway, and the third layer by Nagpur metro rail.
The flyover highway is built at the height of nine metres, and the metro at 20 metres.
While 2.7 km of this multi-layered corridor has a four-lane road on its second level, half km has a six-lane road.
NHAI has used RIB and spine techniques to build this viaduct.
The three metro stations built along this double-decker viaduct are Chattrapati chowk, Jayaprakash Nagar and Ujwal Nagar.
According to officials, this project has led to savings on land acquisition and construction costs and also reduced the travel time to the airport from the earlier 30 minutes to mere 4 minutes.
In February 2021, the union government allocated Rs 5,976 crore for Nagpur Metro Phase-II.
The Nagpur Metro Rail Phase II Project, spread over 43.8 km in length with 32 stations, covers the rural parts of the Nagpur district and will serve as an extension to the ongoing first phase.
Just as the Nagpur phase I, phase II also has four corridors and will be entirely elevated.
