The towers that support the Golden Gate Bridge's suspension cables are smaller at the top than at the base, emphasizing the tower height of 500 feet above the roadway

It is suspended with the big wires that go to the towers form the edges of the bridge
It is a two tower has a suspension bridge.
Although I am not familiar with the detailed design, I am sure there was many shapes used in the construction of the Golden Gate Bridge, including I beams, box beams, angles and plates. But the most familiar shape is that of the main cable, which has a cross-sectional shape of a circle, but when looked at from the side, forms the shape of a parabola. The Golden Gate is different than the common suspension bridge designs of the New York bridges, in that its "sag ratio" (the ratio of the vertical plunge to the span) of the main cable is larger. So although the main span is shorter than the Verrazano Bridge, it's towers are taller. This makes the force in the cable less (better - can be lighter), but the towers are taller, requiring them to be stiffer to resist buckling of a taller column (worse - must be heavier).
The Golden Gate Bridge is a suspension bridge. Suspension bridges are a good way to span a wide gap because they need only two support towers. These towers are usually on land or in the shallowwater near the shore. Strong cables hang between the two towers. The ends of the cables are attached to heavy anchorpoints on land. Small cables, called stringers, hang down and hold the deck in place.
