Regarding The Concrete Mile. Edison's original concrete road was replaced years ago. At that time, 3 blocks from the original road were placed in the new road. However, as of 2010, those blocks are gone.
Additional commentary.
1. Concrete Mile installation
Thomas Edison owned, built and operated the concrete plant but Salmon Brothers construction of Stanhope NJ built the road, installed the concrete and they are still in business today. My Dad and uncles are in there 80s now and have stories of when their grand father built the road.
