This is a three mile long and one mile wide body of water that connects the Pacific Ocean to the San Francisco Bay.

Before the Golden Gate Bridge, there was a bustling ferry system that ran people and commerce between San Francisco and the Redwood Empire to the north.

It's actually unknown how many people worked on the Golden Gate Bridge at the time of construction because records were scarce from that time.

Uh, today we have close to 200 employees who work to maintain to paint toe weld thio.

Make sure that the bridge is in good on safe operating condition.

So we're right now getting sand blasting on the outer part of the bridge, which is up underneath right now where the walkway is, where the pedestrians, right after 3 30.

So the car's air probably just about 15 ft out.

You can't feel it, but the bridges by moving, you know, like this house.

We're standing in a containment like this.

A rough estimate.

16 people sandblasting for a month and a half are painters will go out to the most critical.

You know, structural areas of the bridge where the fog and the salt and the wind has corroded the paint.

The salt eats this bridge, the fog Eat this bridge up.

If we don't continue to paint it, it's just gonna rot away.
