Alignment of hill roads

Alignment of plain roads
|
1. Sharp curves are to be provided 2. Cost of construction is more 3. Proper care has to be taken for drainage 4. Stability is more important due to problem of landlsides 5. Here, more cutting and filling takes place 6. Slope/ gradient is more 7. Alignment is difficult

1. Sharp curves are not to be provided 2. Cost of construction is comparatively less 3. Drainage does not cause that much problem as compared to hill roads 4. There is not much problem of landslides. 5. Comparatively, less cutting and filling takes place 6. Slope/Gradient is less 7. Alignment is easy
