Many people living near the bay probably know about the Dumbarton Railroad Bridge. This bridge was built in 1910 and was the first bridge to span San Francisco Bay and collapsed in 1988 due to a fire. Since then, the plans for the bridge were canceled and nothing has happened since then. I plan on trying to see if I can get to the swing bridge via kayak or some other means of water travel, and plan to climb onto the accessible section another time.

1. Railroad house right off the tracks. Will explore another time and see if I can get in, went to the back and it's all boarded off. Maybe a way in from the top?

2. Railroad lights are still up

3. I wonder what the tubular like structure is between dumbarton and dumbarton railroad bridge? Looks like it pumps out water.

4. This part is totally collapsed.

6. Fun picture

I plan on going to the house on top of the swing bridge someday. Will reply to this thread when done.

for when you become a full member that pipeline in your photo is already in the database but could really use some new or more exciting photos, stories, write ups, etc.

Will do.

The "Tubular Structure" is part of the Hetch Hetchy water pipeline that carries fresh water from the Mountains to the Bay Area, emptying into Crystal Spring Reservoir in San Mateo County. It is owned by the SF Water Dept. Part of the pipeline is submerged under the bay and surfaces here. There is a pump station nearby. This picture is likely the portion near East Palo Alto.

Thank you so much. Do you know what's in the swing bridge house by any chance.

I have never been in it so I don't know firsthand.

I used to live in the Bay and before I moved I was planning on visiting this but never had the time. From my research I think it would be easier to access the bridge from the eastern side, I can maybe give some more info in messages. As you said though accessing the actual drawbridge house probably requires some watercraft. You could probably also access the hexagonal aqueduct tower in the middle of the Bay with some sort of kayak.

If using watercraft I would be mindful of the tides, don't get caught in the bay mud. Menlo Park will have to use their AirBoat to rescue you
