The girders cantilever outward beyond the tower to form a 52 ft observation platform, the girders stopping 10 ft before the edge of the platform. A 6 in. thick slab comprising a steel plate and concrete fill in combination with a clear glass guardrail allow the last 10 ft of the observation platform to cantilever, enabling visitors to feel as though they are floating above the park as they take in striking views of Santa Catalina Island.
