Nagpur Metro And NHAI Achieves Guinness World Record For Building Longest Double Decker Flyover
- The Guinness Book of World Record’s recognition is for building the longest double-decker viaduct.
- The viaduct consists of an elevated highway and Metro Rail supported on a single-column pier.
- 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 achieved the Guinness Book of World Record’s recognition 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 already recognised this engineering feat. They have also recognised another record of constructing three metro stations on a double-decker viaduct.
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.
Union Minister for Road Transport and Highways Nitin Gadkari in a series of tweets congratulated NHAI and Maha Metro on achieving the Guinness Book of World Record in Nagpur.
