Daniel graduated from Purdue University and started his career working on U.S. Highway bridges, interstate bridges, and county crossings throughout Indiana. Daniel has also designed bridges overseas in Azerbaijan and assisted in getting local structural staff into the office in the country’s capital Baku. After obtaining his professional engineering license, Daniel went back to school in the evenings to obtain an MBA from Butler University. This led to him leading bridge departments for the subsequent 10 years. Daniel has since been working with Jim and increasing his focus and passion for historic bridges.

A Purdue University graduate, Jim Barker started his career completely separate from bridge engineering -- designing rockets. Once Jim decided that was not for him, he obtained a master's in structural engineering from the University of Colorado and entered into bridge engineering. Eventually, he took a keen interest in historic bridges and has been focused on them ever since. Jim has worked on most of the historic bridges in Indiana. He has co-authored several books, prepared essays for the National Parks Service, and has given many presentations on the subject over the years.
