Robert Halligan was an engineer and information officer of the California Department of Transportation. During his 45-year career there, he helped state Highway 24, and convinced CalTrans to celebrate the 50th anniversary of the Bay Bridge by by stringing lights on the cables of the suspension spans - a temporary change which later became permanent.
