Kathmandu, Nov 5 : The first-ever modern tunnel expressway, Nagdhunga-Sisnekhola, is expected to be a milestone in the area of road infrastructure and transportation of Nepal.    
The planned construction of 'flyover' besides tunnel along the route also is considered to a leap forward in road infrastructural development.    

It would not only ease traffic congestion and stagnation on the road stretching from Kalanki to Naubise but also contributes to the country's efforts for prosperity.    
According to the Detailed Project Report (DPR) developed by Japan International Cooperation Agency (JICA), the investment made in the tunnel highway would be raised within seven years.    
The sophisticated tunnel highway with flyover is considered to be a panacea to address snarling traffic jam surfaced along the Kathmandu entry route. The construction of the structure is gaining momentum with its foundation stone laid by Prime Minister KP Sharma Oli on last October 21.    

Technically a tunnel highway stretching over 500-metre is considered modern. Ventilators are also arranged for air and light passage in the tunnel structure.    
There are three tunnel routes having length less than 500-metre in Nepal. The Nagdhunga-Sisnekhola expressway is so far the first having length over 500 metres.    

Though the expressway was envisioned around one and a half decade ago, its construction was not taken ahead due to several aspects including financial management.    
The agreement to this effect was signed with JICA agreeing to extend financial and technical assistance. In the last month, the government had inked an agreement with Japanese construction firm, Hazama Ando Corporation, to construct the tunnel project.
