🔍 Key Concepts

• Bridge lighting and signals under 33 CFR Part 118 – Bridge Lighting and Other Signals • How movable spans/draws are marked so vessels can safely locate the navigable channel • Differences between lights, shapes, and daymarks used on bridges

💭 Think About

• Ask yourself: which choice sounds like a formal, standardized signal specifically intended to show the exact location of the opening/draw to a vessel at night? • Think about other places you’ve seen blue lights or Morse code lights used on the water – are they normally for bridge draws, law enforcement, or something else? • Which option describes a marking that would be symmetrical on both sides of the draw so you can line up your vessel through the opening?

✅ Before You Answer

• Verify in 33 CFR Part 118 how the center of the navigable channel and the ends of the draw span are lighted on floating bridges. • Check which color(s) are commonly used to mark bridge spans and obstructions (hint: think red/green/white, not unusual colors). • Confirm whether Morse code is normally used for permanent bridge markings or more for special aids/occasional signals.
