Refer to the IRC recommendations for extra widening of pavements on hill roads:

For a curve with radius:

Less than 25 m: 1.5 m.
25 m to 50 m: 1.0 m.
50 m to 100 m: 0.6 m.
100 m to 300 m: 0.5 m.
More than 300 m: 0.0 m.
So, the Answer is 0.5m.

1.0m is the correct answer.

As per IRC, in hilly roads r>50m, so no need to provide extra widening.
Mangesh said:   5 years ago
As per IRC if r>300 then no need to provide extra widening.
If r<50 then extra widening provided on only one side.
And if 'r' is 8n between 50 to 300m then extra widening provided on both sides.

Recommended by Indian Roads Congress.

For hill roads, the radius 150 metres no need to provide extra widening for any type of Road.

For 1 lane road if R>60--> Ew= 0.
For 2 lane road if R>300--> Ew= 0.
Manish said:   6 years ago
150 lies between 5>R>300, so EW provide in both side.
