Which structure defines the NORTHEASTERN BOUNDARY for PONTOON, CAPE HORN, and EDGE WATER?

• A. BARRANCAS AVE BRIDGE
• B. 3 MILE BRIDGE
• C. BOB SIKES TOLL BRIDGE
• D. PENSACOLA BAY BRIDGE

Answer: (B)

Boundaries in this area are drawn using stable, easily identifiable landmarks that crews can rely on for navigation and safety tasks. The Three Mile Bridge marks the northeastern limit for Pontoon, Cape Horn, and Edge Water because it sits at the edge where those shore areas meet the open waters to the northeast, providing a clear, fixed reference point on charts and in field operations. Using a well-known bridge as the boundary helps ensure everyone can quickly determine the extent of the designated area without ambiguity.

The other structures listed do not define that northeastern edge—they sit in different positions or cross different channels, so they aren’t used as the boundary for these particular areas.
