The Nagpur metro rail project in Maharashtra was recognised by the Guinness Book of World Records for constructing the longest double-decker viaduct with an elevated highway and Metro Rail supported on a single-column pier.
This engineering achievement has already been recognised by the Asia Book of Records and the India Book of Records. They also acknowledged the achievement of building three metro stations atop a double-decker structure.
This 3.1 km double-decker viaduct was jointly constructed by Maha Metro and NHAI on Nagpur’s Wadha road.
A three-layered transportation corridor was made possible by this double-decker viaduct, with an existing highway occupying the first layer, a flyover highway occupying the second, and Nagpur metro rail occupying the third.
The metro is built at a height of 20 metres, while the flyover highway is built at a height of nine metres.
On its second level, this multi-layered corridor’s 2.7 km of four-lane roads and half km of six-lane roads.
This viaduct was constructed by NHAI using RIB and spine technology.
Officials claim that this initiative has decreased travel time to the airport from the previous 30 minutes to just 4 minutes while also saving money on land acquisition and building expenditures.
Nitin Gadkari, the Union Minister for Road Transport and Highways, congratulated NHAI and Maha Metro on setting the Guinness Book of World Record in Nagpur in a series of tweets.
