First, it's because heavy vehicles such as trucks and semi-trucks find it tough when moving on a steep hill. ... Riding a bicycle up a hill can be a very challenging task but riding it on a zig-zagged road makes it easier to go up and down. Making it curved ensures that it's flatter even though it becomes longer.
