Since 1921, 189 California Department of Transportation employees have been killed in the line of duty. One of the biggest hazards is from motorists who do not exercise caution while driving where highway workers are present.
Each spring on statewide Workers Memorial Day, Caltrans honors these employees during a memorial tribute at the State Capitol and by placing any new names on a memorial plaque in the lobby of the Caltrans Headquarters building in Sacramento.
