CHENNAI: Soon, the National Highways Authority of India will convert the six-lane stretch of Grand Southern Trunk road (NH- 32) between Vandalur and Guduvancheri into an eight-lane road. The move is likely to ease congestion on the route. The national highways wing of the State has been entrusted with the widening works on the 5.3 km stretch, which will be taken up at a cost of Rs 42.4 crore.
