This is a pretty interesting pamphlet that covers road building jobs that E.C. Gerber Construction Co., did all over the state of Oregon starting 1930-1978.
Most of the book covers the 30's and 40's and how different road building was before the modern freeways that we are so used to. This was back in the day when roads were muddy rutted paths at best at worse they were non existent.
E.C. Gerber Construction was based out of Oregon City, Oregon not far from where I grew up. I recognized a lot of the places and some of the family names that he mentioned, so this book kind of took me back in time a bit.
This book was self published.
