🔍 Key Concepts

• Lateral system of buoyage in U.S. waters (IALA-B) • How main channels and secondary/adjacent spans are distinguished on bridges at night • Typical color and characteristic used to show safe passage vs. hazards/obstructions

💭 Think About

• Ask yourself: What light color is normally associated with marking a safe preferred channel or span under a bridge? • Consider: Are adjacent bridge piers meant to guide you through them, or warn you away from them? How would that affect the light color and type? • Think about whether a complex flashing or occulting characteristic is needed for fixed structures close to the main span, or if a simple, steady light better fits their purpose.

✅ Before You Answer

• Verify which light color is used on adjacent/obstruction piers when the main navigable span already has lateral system lights. • Check whether the light is normally fixed (steady) or flashing/occulting for nearby hazards around a bridge opening. • Confirm that the marking makes it obvious to a mariner at night which span is the correct channel and which ones should be avoided.
