DETAILED DESIGN FOR WIDENING OF NATIONAL HIGHWAY 54 : PACKAGE 4 & 5 – MIZORAM

National Highway 54 (NH – 54):Package  4 & Package  5 in the State of Mizoram is intended to provide “last mile connectivity” to the remotest corners of the country of India. The development of the National Highway – 54 in difficult mountainous terrain will contribute largely to the economic development of the hitherto remote areas and will also provide strategic defense infrastructure.

The state of Mizoram is one of the “Seven Sister” states of the North-East India, endowed with vast treasure of flora and fauna. It is a border state with the country of Myanmar and hence have significant strategic importance. The NH – 54 is the lifeline of the state connecting it to the rest of the country and the project is aimed at capacity augmentation of the existing highway from Aizawl (capital City of the state) to Tuipang, the last town near Indo/Myanmar border. ​

Key features of the project

• Geometric Improvement to cater for Design Speed of 30 km/hr. The existing geometry of the project road is compliant to 10-15 km/hr Design Speed and thus the improved Project Road will augment the road operation and road safety to substantial limits
  
  
• Capacity Augmentation to 2 Lane with Paved Shoulder ​
  
  
• Significant length of earth retaining structures both in hill and valley side to ensure sustainable all-weather road​
  
  
• Specialized Slope protection and safety measures like Rockfall Prevention System with Soil/Rock Anchors, etc. to ensure slope stability in highly vulnerable “Lushai Hills” of Mizoram, consisting of highly fractured and young sedimentary rocks
  
  
• Adequate Surface and sub–Surface Drainage system
