Walk down the Embarcadero toward Fisherman's Wharf and you’ll see it. It’s impossible to miss, yet most people just walk right under the thing without a second thought. I'm talking about that massive, skeletal wooden structure that looks like a gateway to nowhere. That is the Pier 43 Ferry Arch. It sits there, weathered and gray, sandwiched between the tourist trap energy of the Wharf and the sleek, modern Bay cruises. Honestly, it’s one of the few pieces of "Old San Francisco" that hasn't been polished into a shiny corporate version of itself.
It’s weird.
If you look at it long enough, you realize it isn't just a decorative arch. It’s a machine. A giant, heavy-duty piece of industrial equipment frozen in time. Back when the Embarcadero was a working-class brawl of sailors and stevedores rather than a place to buy sourdough bread bowls, this arch was the heartbeat of the city's logistics.
What the Pier 43 Ferry Arch Actually Did
Before the Golden Gate Bridge or the Bay Bridge existed, San Francisco was basically an island. Not literally, obviously, but for all intents and purposes, if you wanted to get heavy freight into the city, you weren't driving it over a span. You were floating it.
The Pier 43 Ferry Arch was built in 1914. It served as a "transfer bridge" for the State Belt Railroad. Think of it as a giant, adjustable ramp. Its job was to link the tracks on the land with the tracks on the railroad barges—known as car floats—that pulled up to the pier. Because the tide in the San Francisco Bay is constantly moving up and down, you couldn't just have a static dock. You needed a way to raise and lower the tracks so the trains could roll off the boat and onto the street without falling into the Pacific.
Those huge overhead pulleys and weights? They weren't for show. They were the counterbalances used to tilt the apron. It’s a masterpiece of pre-World War I engineering that still looks like it could function today if someone just greased the wheels and hit a switch.
The Belt Line Connection
The State Belt Railroad was the glue that held the waterfront together. It ran the entire length of the Embarcadero. Every pier had a spur. If a ship arrived from Honolulu with sugar or from Seattle with timber, the Belt Line moved those goods to the warehouses. The arch at Pier 43 was the primary gateway for the Northwestern Pacific and Western Pacific railroads.

Basically, this arch was the city's front door for stuff.
A Near-Death Experience in 1998
Most people don't realize how close we came to losing this thing forever. In 1998, a massive fire ripped through Pier 43. It was one of those classic San Francisco waterfront blazes—creosote-soaked wood burns like a matchstick. The pier itself was devastated. The arch, being made of heavy timber and steel, was charred and scorched.
For a while, it looked like it was headed for the scrap heap.
The Port of San Francisco and various preservation groups had to make a choice. Do you tear down a "useless" piece of old machinery, or do you spend the millions required to seismically retrofit a wooden skeleton? Thankfully, the city leaned into its history. They spent roughly $5 million to restore the arch, completing the work around 2003. They didn't just fix the burn marks; they reinforced it so it wouldn't collapse during the next Big One.
Today, it stands as a designated San Francisco Landmark (No. 128). It’s a survivor.
Why It Looks the Way It Does
You’ll notice the wood has a very specific, silvery-gray patina. That’s not just age; it’s the result of being blasted by salt air for over a century. The design is a "bascule" type of structure, though it operates more like a vertical lift.

The aesthetic is purely functional.
No gargoyles.
No filigree.
Just raw utility.
The Pier 43 Ferry Arch is one of the last remaining examples of this specific type of maritime-rail technology on the West Coast. While most other cities tore theirs down to make room for condos or parking lots, San Francisco kept its weird wooden gateway. If you stand directly underneath it and look up, the scale of the timbers is actually pretty intimidating. These are massive beams, the kind you just don't see in modern construction anymore.
The Neighboring Competition
Just a few steps away, you have the SS Jeremiah O'Brien and the USS Pampanito. These are huge, impressive vessels that grab all the attention. The arch gets overshadowed. But without the arch, the industrial ecosystem that supported ships like those wouldn't have functioned. It was the bridge between the water and the rails.
Exploring the Area Around the Arch
If you’re heading down there to see it, don’t just snap a photo and leave. There is a specific "vibe" to this section of the waterfront that is easily missed.
- The Promenade: The walk from Pier 39 to Pier 43 is the most tourist-heavy stretch, but right at the arch, the crowds often thin out slightly as people head toward the ferry departures.
- The Night View: Go at night. The Port of San Francisco has installed subtle lighting on the arch. It looks haunting. The shadows cast by the pulleys make it look like a ghost ship sitting on the shore.
- The Sounds: Listen for the sea lions at nearby Pier 39, but also notice the creaking of the remaining wooden pilings. It’s one of the few places where you can still hear the "old" harbor.
One common misconception is that this was a passenger terminal. It wasn't. While the nearby Ferry Building (at the foot of Market Street) was the grand palace for people, Pier 43 was for the heavy lifting. It was the blue-collar cousin.
Practical Steps for Your Visit
To actually appreciate the Pier 43 Ferry Arch, you need to see it from a few different angles.

- The Approach: Walk from the Ferry Building northward. This allows you to see the arch framed against the backdrop of the modern cityscape, which highlights the contrast between the 1914 engineering and the glass towers behind it.
- The Close-Up: Walk directly through the arch. Look at the steel cables. Notice the massive concrete counterweights. It gives you a sense of the sheer physical force required to move the railroad apron.
- The Water Side: If you take a Red and White Fleet cruise (which departs right next door), look back at the arch from the water. This is the view the barge captains had as they navigated car floats into the slip during a thick San Francisco fog.
Actionable Insights for History Buffs
If you want to dive deeper into the history of the San Francisco waterfront, don't just stop at the arch.
Check out the San Francisco Maritime National Historical Park located just a few blocks west at Hyde Street Pier. They have a collection of historic ships that would have been contemporaries of the arch's peak operating years.
You should also look for the remaining "Belt Line" tracks embedded in the asphalt of the Embarcadero. You can still follow them for long stretches. They lead directly toward the arch, showing you exactly how the trains moved through the city.
Finally, visit the San Francisco Railway Museum near the Ferry Building. It’s small, but it provides the necessary context for how the streetcars and the Belt Line railroad created the transit network that defined the city before the era of the automobile. The arch wasn't an island; it was a node in a massive, interconnected web.
Stop thinking of it as a gate. It’s a machine. A big, beautiful, 110-year-old machine that refuses to quit.
