How We Built a Golden Gate Bridge Balloon Sculpture in San Francisco

We built a red Golden Gate Bridge out of over 2,000 balloons for a corporate event in San Francisco, 12.5 feet tall and 22 feet long, in the Golden Gate Room at the San Francisco Marriott Marquis. It took about 20 hours of work in all. Here's how it came together, from a bare frame at our Pleasanton studio to the finished bridge on Monday, August 10, 2026.

A San Francisco landmark for a corporate event

The ask was simple to say and big to build. The client wanted the Golden Gate Bridge in balloons, about 12.5 feet high by 22 feet long. Their inspiration photo had marquee letters and flowers, and they asked us to leave those off and let the bridge stand alone.

This was one of the biggest projects we'd ever taken on, and when we said yes, we weren't sure exactly how we were going to build it. A 22 foot bridge had to stand on its own under a ceiling only about 14 feet high, look like the Golden Gate from across the room, and be done before guests walked in at 7pm.

That meant the shape had to do all the work. We kept everything red. Two towers and the sweep of the cables are what people recognize first, so those got the most attention.

The room set the limits. The dock opened for us at 11:30am, and nothing could be tied to the walls or ceiling.

How we built the Golden Gate Bridge in balloons

Step 1 - A frame built at our Pleasanton studio

Every balloon sculpture starts with something you never see. My husband Kyle built the frame at our Pleasanton studio, with metal rods as the uprights, PVC pipe for the crossbars, and flanges screwed into base plates.

He test built it outside and duct taped every joint in a crisscross so the frame would stay solid under all those balloons.

Step 2 - Hours of inflating at the studio

The balloons took longer than anything else. All together the bridge took about 20 hours of work, and most of that was prep and inflating at our studio between August 6 and August 10.

We're a family operated business, and this was a family job. Our kids helped load the parts into the truck the morning of the install.

Step 3 - Loading in at the Marriott Marquis

We pulled up to the hotel dock at 11:30am, and the hotel crew helped us unload. Once everything was inside, we laid the tower sections out across the ballroom floor and showed the hotel crew a photo of what we were building. Long posts were the tower uprights and short ones were the crossbars, two uprights per tower.

Step 4 - Building the towers around the frame

This is where most of the bridge happened. We had balloons around every piece we could before we got there, so on site we joined the sections, duct taped every connection all the way around, and added clusters to fill in the gaps. When one slipped loose early on, we went back and checked the rest.

Some spots fought us. A few gaps were too tight for a whole cluster, so we pushed single balloons into them. Where a cluster sat wrong, we took it off and refit it so the connector points wouldn't show.

When the first tower stood up, it looked a little short for the length of the bridge. I inflated more balloons and added a top row to make it a little taller, so the towers felt in proportion with the span. Then there was one corner I couldn't leave alone, so we brought it back down and straightened it.

Step 5 - Raising the towers on weighted bases

With the towers covered, we raised them onto their base plates and lined them up across from each other. The base plates hold everything, so the bridge stands without touching a wall or the ceiling. That's also the moment we found out the ceiling really was about 14 feet, with a little room to spare.

Step 6 - A link balloon roadway

The road is made of link balloons. I made strands of them like pearls, twisted the strands together, and then tied them together into the road.

We tied the road on from underneath. Then we secured the whole bridge first and only flattened the road after that, because until it's tied, it keeps moving. We also left balloons off the road crossbeam on purpose.

Step 7 - The suspension cables

The cables are what make it read as the Golden Gate. We ran strands of red link balloons from the tower tops down to each end and let them hang with a little sag. Each one gets two knots, because a single knot doesn't hold.

The finished bridge in the Golden Gate Room

About five hours after we reached the dock, the bridge was done. The client came down, looked it over, and told us it looked great. A few days later, their events director told us the bridge, the arch and the photo op were a hit with the client and the whole group.

Planning a large balloon sculpture in a San Francisco hotel ballroom

If you're dreaming up something this size, here's what we'd tell you from this one.

Send us the ceiling height first. A 12.5 foot bridge under a ceiling of about 14 feet works, but only just. Room photos and the venue contact help us check the scale early.

Plan the dock time with the hotel. Our window ran from an 11:30am load in to a 7pm start, and teardown came after the event ended at 10pm.

Build the frame before the event. Test building at the studio is how we knew it would stand on the day.

Pick the two or three shapes guests have to recognize, and let the rest go. For this bridge it was the towers and the cables.
