Construction of Nagdhunga tunnel route continues even amidst pandemic

Most of the sectors across the nation have come to a standstill due to the onslaught of a new variant of coronavirus, construction of the Nagdhunga tunnel route is underway at a regular pace.

According to the project, construction activities have been forwarded by adopting all health safety protocols even in this pandemic.

More than 650 workers are now working in the project even as before. Project chief Nareshman Shakya said that no one is allowed to enter the construction site as much as possible and allow to enter those for essential work only after health tests.

Entry of the people except people associated with the project have been prohibited at the construction site.

All the people associated with the project have adopted health safety protocols and arrangement has been made to accommodate the person suspected of coronavirus infection, even after adopting health safety protocols.

A 10-room isolation ward has been constructed at the construction site where 25 people can be accommodated. Arrangements of separate camps, where 25 people can be accommodated, have been made at three places.

Shakya added that the project has also made an arrangement of oxygen cylinder and medical team to resolve the problem immediately if some problems occur at the construction site. Similarly, an ambulance has also been kept in a ready position if it needs.

He said, “We have made arrangements of all required things as much as possible.”

There is no lack of human resources and construction materials. Shakya mentioned that construction activities are underway by following prohibitory order.

The construction works have been delayed by one month from the schedule. Although the construction was stalled due to the Covid-19 pandemic last year, it was not much delayed as per its schedule.

The Project has said works are on regarding construction of the tunnel way both on Kathmandu and Dhading sites.Three excavators out of five are being employed in the construction at present.

He said construction works can be carried out from four sites once the works on the construction of the underpass in Dhading are over. The works on the tunnel would be further expedited after this.

The plan is to complete the construction of the underpass in Dhading within one month while the construction of an overpass at the opening of the tunnel way in Kathmandu has reached to completion stage.

9% progress in Nagdhunga-Sisne Khola Tunnel Project

The construction of the Nagdhunga-Sisne Khola Tunnel started from three sections on December 23. The work is being carried out 24 hours a day. 

Naresh Man Shakya, director of the Nagdhunga Tunnel Project, said that the project has seen nine percent progress. “The construction of the tunnel is in full swing,” he said. “There were obstacles at the beginning, but now the construction has gained momentum.”

Shakya said that the tunnel is being dug from three sections. “A maximum of six meters of tunnel is being dug daily,” he said. “The speed of digging the tunnel will increase after hard rock is found.” According to the project, the main tunnel will be 8.2 / 15 meters. This tunnel is being dug using the New Austrian Tunneling Method (NATM) method.

Project director Shakya said that a 139-meter tunnel has been dug towards Dhading (west). “A 49-meter tunnel has been dug on the evacuation side of Kathmandu,” he said. “A five-meter tunnel has been dug in the third section.” 

The project is currently working in two shifts- day and night. The tunnel is being dug using drill and blast technology. The project will be dug like the Melamchi Drinking Water Project. The total length of the tunnel will be 2.68 kilometers. 


The project aims to build two tunnels with the length of 9.5 meters and 4 meters, respectively. The project hopes to complete the tunnel in 16 months. 

It is estimated to cost around 22.5 billion rupees, including two 500-meter roads and two flyovers and tunnels and compensation for affected people of Dhading and Kathmandu. The contract for the construction of the project was awarded to Hajma Ando Corporation, a Japanese Company. Prime Minister KP Sharma Oli had laid the foundation stone of the tunnel in 2019.

The tunnel was started with the loan assistance of Japan International Cooperation Agency (JICA) on November 14. JICA has agreed to provide 16 billion rupees for the construction of the tunnel and the government will invest 6 billion rupees. 

Project director Shakya said that the construction of flyover structure is being started towards the main tunnel of the project in Dhading, near the depot of Nepal Oil Corporation. Shakya said that the main tunnel of the project will be in Dhading and a flyover will be constructed near the depot of Nepal Oil Corporation. 

“The construction of flyovers and access roads will also pick up speed soon,” he said. The project will have to construct 500 meters of access road on both sides of Dhading and Kathmandu.

Construction of Nagdhunga tunnel starts

Construction of the Sisnekhola-Nagdhunga tunnel road has finally begun after a long wait.

According to the tunnel road project Chief Engineer Nareshman Shakya, tunnel digging started from Tuesday from Sisnekhola point of Tribhuvan Highway in Dhunibesi Municipality, Dhading.

Once the construction is finished, the tunnel road will greatly ease the huge traffic congestion often seen on the Naubise-Nagdhunga section of the highway. The 2.38-km tunnel road will have two lanes each 3.5 metres wide and will reduce the Naubise-Thankot distance by 8km.

Under the project, 2.3km road up to Thankot’s Basnet Chhap and 565 metres from Sisnekhola of Dhunibesi of Dhading will also be upgraded and black-topped. After conducting surveys in different phases, the government had finally taken the national glory project ahead.

As per the contract, the contractor Hazama Ando Corporation will finish the project and hand it over to the government by April 2023. More than 300 workers are deployed at the project site at present.
