Bangalore - Mysore
140 Odd Kms
Smooth 4 Laned Road, Nevertheless the most Dangerous Road in Karnataka mainly due to the unscientific placement of Road Humps which are almost invible until you reach a spot where u can do nothing but juggle over it and damage a Fork and possibly a Bone...There are about a couple of Dozen Road Humps(Really Big ones) on this stretch with no sign boards what so ever. Also the Human intruders who always need to cross the road in a hurry to attend the world meeting...Add to it the Stray dogs and cattle.
