When I got this book from the library, I did not list it here because I was not sure I would read it. But as I started reading, it became clear, I was hooked. It is not a page turner, but I found I needed to read a few more pages every night before I went to bed. Living in the Bay Area, I am well aware of this bridge and could envision the process of building and rebuilding it, even though I do not use it regularly. I am not technically aware of all the aspects discussed but gained a great appreciation for what was involved. And I could certainly relate the decisions and politics involved in the construction–especially the reconstruction since the earthquake. The book was fascinating and I will never be able to use this bridge, or any other, again with out a whole new perspective and appreciation for the wonders of the modern world.
