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.
