Cabinet Approves Bihar Highway Four-Laning to Nepal Border
India’s Cabinet has approved a plan to make an important highway in Bihar four lanes wide.
The road will run between Muzaffarpur, Sitamarhi and Sonbarsa near the Nepal border.
The project will cost about Rs 3,590.73 crore.
Officials say the wider road will reduce traffic jams and make travel safer.
It should also help trucks carry goods more quickly.
The road will connect businesses, railway stations, markets and the Nepal border.
It will include bridges, railway overbridges and flyovers.
The government also expects it to help tourism, farming and trade.
The project will be built using the Hybrid Annuity Mode.
The Cabinet approved four-laning of the 82.578-km Muzaffarpur-Sitamarhi-Sonbarsa section of National Highway-22 in Bihar.
The project has a total capital cost of Rs 3,590.73 crore and will be implemented under the Hybrid Annuity Mode.
The corridor will connect Muzaffarpur with Sonbarsa near the India-Nepal border and link with NH-27 and other national freight routes.
The upgraded highway is intended to reduce congestion, improve safety and speed up passenger, freight and agricultural transport.
The project includes seven major bridges, three railway overbridges and two flyovers, including a 340-metre bridge over the Bagmati River.
