Officials chose a net for the Golden Gate Bridges proposed suicide deterrence project. Why is a net feasible for the Golden Gate Bridge and not the Aurora Bridge?
The Golden Gate Bridge is suspension bridge with many of the key structural components close to or above the roadway surface. The Aurora Bridge is a cantilever truss bridge with the key structural components completely below the roadway surface. On the Golden Gate Bridge, a net 20 feet below the sidewalk does not restrict the ability of inspection and maintenance crews to access structural components. On the Aurora Bridge, a similar net would severely impede inspection and maintenance operations, and block access by an under bridge inspection truck (UBIT). The Golden Gate Bridge extends over water and unpopulated land. More than two thirds of the Aurora Bridge extends over residential and commercial areas. A net extending 20 feet below and 20 feet outside of the bridge would be in lateral and vertical conflict with many structures. In addition, the “visual footprint” of the bridge would become significantly larger when viewed from neighborhoods below the bridge.
