What is the location of the Washington Street emergency exit?

The correct choice highlights the specific location of the Washington Street emergency exit, which is situated between Junction 5 and Newport in Tunnels E and F. Identifying emergency exits is crucial for safety protocols in engineering environments, particularly in complex structures like tunnels where immediate access to exits can be a matter of safety during emergencies.

In this context, Junction 5 serves as a notable reference point that helps in pinpointing the emergency exit's position relative to other known junctions. The mention of Tunnels E and F emphasizes that the exit is integrated into the tunnel system, which is essential for emergency planning and response strategies.

The other options provide different junctions and tunnels, but they do not accurately reflect the actual location of the Washington Street emergency exit, which may lead to confusion or hinder an effective evacuation during an emergency. Identifying the correct location minimizes response time and enhances safety, demonstrating the importance of precise knowledge about emergency routes in engineering and facility management.
