The Supreme Court on Wednesday wondered why felling of trees was necessary to widen roads or to keep them aligned in a straight line, and suggested that roads could instead be zigzag, which would help reduce speed of vehicles and save lives by avoiding accidents.

A bench headed by Chief Justice SA Bobde said: "Why do roads have to be laid in a straight line by cutting trees? Keep the roads zigzag. It will reduce speed of vehicles, and also decrease road accidents and save many lives."
