Which hazard is indicated by the sign Opening or Swing Bridge Ahead?

• A. Bridge Opening Ahead
• B. Railway Crossing Ahead
• C. Low-Flying Aircraft Ahead
• D. Opening or Swing Bridge Ahead

Answer: (D)

This sign warns of a movable bridge ahead that can open or swing to let water traffic pass. Because the bridge may not be passable while it opens, there can be a noticeable delay and a wide gap in the road. You should slow down, be ready to stop, and follow any signals, barriers, or directions from a bridge operator. Don’t attempt to cross when the barriers are down or lights indicate stop; wait until it’s safe to proceed. This is the specific hazard the sign is highlighting, distinguishing it from a fixed bridge or other road hazards.
