NHAI to take up studies to assess best options for road projects in hill states
NEW DELHI: The National Highways Authority of India (NHAI) will soon undertake detailed studies to assess the most suitable options — hill-cutting, viaducts or tunnels — for executing highway projects in hill states.
The decision was made at a brainstorming session held last week on strengthening quality control in highway construction. Sources said some experts pointed out that the cost of stabilising slopes after cutting hills is nearly equivalent to that of constructing tunnels. They also suggested that future projects incorporate a balanced mix of all three approaches instead of relying predominantly on hill-cutting.
