If you've ever driven up or down the Pacific Coast Highway (known as PCH, especially from Newport Beach, south) from Carmel to Hearst Castle, you know how narrow and winding and cliff abutting this highway is. The experience and the view are worth every nerve wracking, brake foot tiring minute. Just avoid driving it, if at all possible, during the Winnebago season. January is pretty good because, not only is it not crowded, you can often see the spouts of migrating whales from the road.
What you might not think up about is, how in the heck did they build it? Here's picture of that construction, sent to me by my sister after she and her family and a student visitor from France had just completed this drive.
Check out Road Trip USA for a description of the entire length of Highway 1. I've driven every inch of this Highway, from Portland to San Diego, and into Mexico, with just a short stretch from Portland to Olympia remaining for me to experience.
