The Siddhababa tunnel in Palpa is the first tunnel that is being built by the government of Nepal with its own resources. No rain or winter. There is no option to travel by trasaitras on the Siddhababa section of the Siddhababa highway. Some of them were killed by the landslide. Stones hurled at the moving vehicle. Over the years, there has been a loss of wealth in this section.
What to do to avoid landslides?
Deputy Prime Minister and Finance Minister Bishnu Paudel says that many options have been sought. "There was always a fear of landslides in this section, many people lost their lives due to landslides," he says, "As the risk of landslides increased every year, we started to look for an alternative to landslides, and among many measures, we finally decided to build a tunnel."
Siddhartha Highway Siddhababa section is in Chure area, as soon as Tarai ends, Siddhababa section will be reached . "There are high mountains, there was a risk of falling large stones, I thought there could be an alternative road," says Poudel, 'Accordingly, the road from Belas in Butwal to Dobhan via Nuwakot was taken, but this road had to go through a long, broken terrain, and it was not safe in all respects.'
The second option was thought of going from East-West Highway to Butwal Industrial Area via Charanga and going out to Jhumsa Jhar to Siddharth Highway. Therefore, a study was conducted to improve the infrastructure so that the journey would be easy, safe and fast through Siddharth Highway, and it was decided whether it would be safe to build a road through Siddhartha's section. But the condition of the land was the same,' he said, 'that also didn't seem very suitable, the other option was to build a three km long bridge over the river, but in terms of cost and technology, it also didn't seem very suitable.' Also suggested rock netting, but this also did not seem suitable . "After that, the matter of building a tunnel came up, and we requested the Swiss government to see if it would be possible to build a tunnel in Chure," says Finance Minister Poudel.
The report was provided by the Swiss government after studying how to make a 'rock set' in places where there is a risk of tunnels and landslides. "After that, this is the first tunnel that the government of Nepal has started building from its own resources," he said, "Prime Minister KP Sharma Oli had already taken information about the damage there by observing Siddhababa, and under his leadership, a detailed project report (DPR) was prepared and the work proceeded." 
Lumbini, Bhairahawa, Butwal and Pokhara are important centers in terms of industry, tourism, etc. He said that not only the tunnel, but also the 165 km section of Siddharth Highway is going to be upgraded to two-lane standard .
Although the contract for Siddhababa tunnel was signed in February 2078, the tunnel digging work was done from June 2080. For convenience and immediate rescue in case of any problems with the vehicles inside the tunnel, the first bypass tunnel of 151 meters, the second of 161 meters and the third bypass tunnel of 130 meters distance have been constructed . The length of the main tunnel is 1,126 meters. Road improvement work will also be done on 2 thousand 398 meters in that section. The term of the initial agreement is till February 2083 . The project claims that the work will be completed within that time.
In the area where the tunnel is constructed, the stones will fall down and make a cemented 'rock set'. Its contract was taken by China State Construction Engineering Company . The contract amount is 7 billion 34 crore 21 lakh rupees. Tunnel under Siddharth highway is being built in Palpa's Tinau rural municipality-3, Dobhan Siddhababa area .
What is the progress of Nagadhunga-Sisnekhola?
The construction of the Nagadhunga-Sisnekhola tunnel is also in the final stage with a subsidized loan of 16.5 billion rupees from Japan. However, there is doubt that the tunnel work will be completed on time as the locals repeatedly obstruct the construction. The Government of Nepal has invested 6 billion rupees in this. The construction of the tunnel is being done by the Japanese company Hazma Endo Corporation.
Currently, the project says that it will take 33 minutes to reach Balumbu from Sisnekhola via Nagadhunga road and 23 minutes when leaving. But the project says that after the tunnel is operational, the KCPD of Balambu will be reached from Sisne river within 7 minutes. Emergency and main tunnels are constructed separately. Emergency Tunnel
The distance is 2 thousand 557 meters. Tutipakha located in Chandragiri in Kathmandu and the main tunnel in Sisne river located in Dhunibensi municipality in Dhading.
The distance is 2 thousand 688 meters. From Kisipdi located in Balambu to the entrance of the tunnel to Tutipakha of the road distance is 2.307 km. Its construction was started on November 4, 2076 . Work is underway to bring the tunnel into operation by October 2082. The tunnel is the first transport vehicle tunnel in Nepal. The road department is studying about two dozen tunnels. Some of the studies have been completed and the report has been put on hold. Some are being studied . Currently, the priority of the government is Sindhuli's Chiabari-Khurkot under BP highway and Dumkibas-Bardghat tunnel under Narayangadh-Butwal road section. The pre-feasibility study of both of these has been completed .
Teabari-Khurkot road
The distance Now it is 29.8 km, it is claimed that it will decrease to 8.5 km if the tunnel is constructed. According to the study, the tunnel distance is 4.90 km . The problem road section is Narayangadh-Butwal . There is more problem in the southern part of Nawalpur under this road. This section has more ups and downs . When the cargo vehicle arrives at the hill, there is a traffic jam even when it breaks down. According to a study in 2080, its total Distance is 5.3 km . According to the preliminary study, 38 billion 69 million rupees are required for construction. Although about two dozen tunnels have been studied, these two tunnels have been given the first priority for construction, says Keshav Kumar Sharma, secretary of the Ministry of Physical Infrastructure and Transport. "Many tunnels have been studied," he said. "Regardless of our geographical situation, we should proceed with regard to the geographical location of the transport infrastructure," he says.
