How is protection provided on a remote-operated bridge while work is being done?

Protection on a remote-operated bridge while work is being done is best provided by contacting a Structures or Signal and Communication employee. This is important because these professionals have the specific knowledge and authority to assess the situation and implement the necessary protective measures to ensure safety. They can provide real-time information and solutions tailored to the specific conditions of the bridge and the ongoing work.

This option recognizes the need for coordination among specialized staff who understand the operational implications of work being done on a bridge. It also emphasizes the importance of safety protocols and communication in maintaining a secure working environment. Other choices don't involve the same level of professional oversight or may not ensure the necessary safety measures are effectively implemented.
