History Highlights - TRB’s Iowa Roots: Anson Marston, Thomas Agg, Thomas MacDonald, Walter Root, and Roy Crum

Learn how five men from Iowa shaped TRB’s earliest decades with their expertise and commitment to research and how they succeeded in part because Iowa exemplified in the extreme the close relationships between universities and state highway departments during their earliest years.

As part of the Centennial Celebration, TRB has initiated the History Highlights series that will regularly release stories that highlight the events and people that helped shape TRB during the last 100 years.

Check out the latest release in the TRB History Highlights series.
