This Michigan Highway Survey and Design Manual is a great resource for those interested in highway design history. To use it, simply open it up and start reading through the pages to learn about the highway survey and design methods of the time. When handling the book, be gentle as it's an older item. Try to keep it away from moisture to prevent further damage to the pages and covers. If you want to store it, place it in a dry and cool place. And remember, since there's already some writing on the pages, it adds to the unique character of the book, so don't worry too much about adding your own notes if you'd like to mark important points.
