In the wake of the October 17, 1989 Loma Prieta Earthquake, Caltrans commissioned an oral history project to document the personal and professional experiences of Caltrans employees who worked to restore the State's damaged transportation system. Joe Wiegand was an Assistant Transportation Engineer/Changeable Message Sign Operator at the time of the Loma Prieta Earthquake.
