When near tunnels and bridges, what is a key arrangement?

• A. Install a new road light.
• B. Shut down a traffic lane.
• C. Widen the road.
• D. Move the job to another location.

Answer: (B)

Shutting down a traffic lane is the practical way to create a safe, protected work zone when you’re near tunnels and bridges. The confined space and the close proximity of traffic mean workers need more room to operate and a clear buffer from vehicles. Closing a lane reduces exposure, gives room for barriers, signage, and possibly flaggers, and helps ensure there’s a safe escape path if something unexpected happens. The other options don’t address the immediate need to control traffic flow in the tight, high-risk area around tunnels and bridges.
