How much does the Golden Gate Bridge make in a year?

One reason the Golden Gate Bridge is a high-value structure is that it enjoys multiple income streams. Total annual revenue averages $145 million a year. As a key infrastructure component for the region, the Bridge is eligible for annual State and Federal Grants. Tolls and fees account for most of the revenue.

Does the Golden Gate Bridge need maintenance?

The truth is that the Bridge is painted continuously. Painting the Bridge is an ongoing task and a primary maintenance job. The paint applied to the Bridge's steel protects it from the high salt content in the air which can cause the steel to corrode or rust.

How do they keep the Golden Gate Bridge from rusting?

The zinc protects the steel, because zinc corrodes more easily than steel. Zinc serves as a sacrificial metal, so the steel does not rust when zinc is present. On top of that zinc primer is a top coat of paint in the Golden Gate Bridge's signature color called International Orange.

How many cars can the Golden Gate Bridge hold at once?

Given the GGB's dimensions, about 1,200 passenger cars can fit on the bridge at once. Crunching some numbers: This means that almost three million tons of weight could be pushed down on the bridge's suspension during rush hour.
