• Aids to Navigation under Bridges in the U.S. Aids to Navigation System (USATONS) • How channel limits are shown when a channel passes through a fixed structure like a bridge • Color meanings for red, green, yellow, and white lights in lateral and special marks

💭 Think About

• Think about how you normally identify the left and right sides of a channel at night when approaching a bridge opening. • Ask yourself which color(s) are usually used for lateral channel edges versus which are used for special marks or warning signals. • Consider whether a vertical line of three white lights sounds more like a signal for safe passage/centerline or for channel edges.

✅ Before You Answer

• Verify how lateral marks (port and starboard sides of a channel) are colored in the U.S. system. • Check what yellow lights are typically used for (e.g., special purpose buoys, towing lights) and whether that matches "edges of a channel" on a bridge. • Consider whether three white lights in a vertical line would show both edges of a channel or more likely mark a single feature (like center or safe span).
