Curve 1.png

The radius of a curve found at change 5 + 560 kms is 64 m. Which should be redesigned to min. radius of 90 m or above.

If redesign of curvature is not possible due to any factors, minimum extra widening of 0.9m is recommended as per IRC:73 for design speed of 30 kmph.

If the provision of extra widening is not possible due to any reason, the Signboard of a Speed limit of 45 kmph should be provided in such a way that it is visible at 60 m distance before the curve, and precautions for speed management should be taken.
