November 4, 1959: A complete closed circuit television and paging system was installed in the tunnel which linked the Central Artery and the Southeast Expressway. The TV system consisted of eight television pick-up cameras in each tube of the tunnel which were then connected to the television monitors in the control building. Charles Sperrazza monitored the system here for any motorist needing aid or other type of mechanical trouble. He could also call out instructions to motorists by means of a public address system. This was of special value in case of a bad accident or fire in which which panic and confusion could be a factor.
