reply to maxpower90 There is a house at the bottom of the mountain here, with a 250' winding driveway that's as steep as this, but a LOT longer and NOT straight, but winding S curves going up to the house. The house itself is built on a steep slope. There is another house 1/4 mile from that one which is also an engineering nightmare of a driveway. You could swear the whole house is going to fall off the cliff. But these developed housing projects should be better designed than what these photos show.
