The Nugegoda Junction is one of the main bottlenecks of the High Level road and about 75,000-100,000 vehicles move along this route daily.
The proposed flyover at the Nugegoda Junction will consist of four lanes to provide a two lane dual carriageway.
The Welikada Junction is another highly congested intersection of the Sri Jayawardenapura-Kollupitiya Road and the Nawala-Rajagiriya Road, with about 71,400 vehicles plying this stretch daily.
Around 72,000 vehicles move daily on the road between Kiribathgoda and Kadawatha Junction, with the narrowness of the road creating heavy traffic congestion.
The proposed project will widen the road section of around 2.5 kilometers from Kiribathgoda to Kadawatha with a two lane dual carriageway.
