Double-decker viaduct in Nagpur (DD Sahyadri)
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.
“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.
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.
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.
