How Long Is The Benjamin Franklin Bridge

Let’s cut to the chase: the Benjamin Franklin Bridge is 9,650 feet long from end to end. That’s about 1.83 miles, or roughly 2,941 meters for friends who think in metric. So if you walk it, you’re in for a proper stroll—not quite a marathon, but definitely not a quick trip to the mailbox.

But wait, there’s a catch. Length can mean different things when you’re talking about a giant suspension bridge. The total length includes the approaches, the anchorages, and all the bits that get you from city street to city street. The main span—the dramatic part hanging over the Delaware River—is a different number entirely.

The Big Number: Total Length

The full length of the Ben Franklin Bridge is 9,650 feet. That’s the measurement you’ll see in most official specs, and it’s the one to use if you’re trying to impress people at trivia night. It stretches from Philadelphia, Pennsylvania, to Camden, New Jersey, carrying cars, buses, PATCO trains, bicycles, and pedestrians.

At 1.83 miles, it’s actually shorter than a 5K, which is 3.1 miles. But it’s still long enough that you’ll feel it in your legs if you walk across and back. Trust me, the return trip always feels a little longer.

The Main Span: The Star of the Show

If you’re talking about the part that makes engineers swoon, that’s the main span. The Benjamin Franklin Bridge has a main span of 1,750 feet, which is about 533 meters. That’s the distance between the two towers, the chunk suspended high above the water.

When it opened on July 1, 1926, that main span made it the longest suspension bridge in the world. It held the crown until the Ambassador Bridge came along in 1929. So for three glorious years, this bridge was the undisputed heavyweight champion of suspension spans.

And yes, it’s still a beast today. The towers rise 385 feet above the water, which is taller than the Statue of Liberty, even if you count her pedestal. Pretty impressive for a bridge that’s almost a century old.

What About Walking or Driving It?

If you drive across, the total length of 9,650 feet goes by pretty quickly. Depending on traffic, you might be on the bridge for a few minutes, or you might have time to rethink your entire playlist. Camden and Philadelphia are close, but the bridge makes them feel connected in a way that’s both literal and symbolic.

Walking is a different story. The pedestrian walkway is open during daylight hours, and it’s a fantastic way to experience the bridge. You get skyline views, river breezes, and a healthy dose of “why did I wear these shoes?”

At a normal walking pace, you can cross the 1.83-mile total length in roughly 35 to 45 minutes. That’s if you don’t stop for photos, which you absolutely will. The Philadelphia skyline is right there, being all photogenic and annoying.

A Quick Math Check

One mile is 5,280 feet, so 9,650 feet divided by 5,280 gives you about 1.83 miles. That’s the number to remember. If someone asks, “How long is the Benjamin Franklin Bridge?” you can say “about 1.8 miles” and sound like a local genius.

But if they want the fancy engineering answer, hit them with 9,650 feet and 1,750 feet for the main span. Then casually mention the 385-foot towers, and they’ll either be impressed or walk away slowly. Either way, you win.

Why the Number Can Feel Different

Bridges are weird like that. A number on paper doesn’t always match the feeling in your feet. On a windy day, the Ben Franklin Bridge can feel like it goes on forever, while on a clear, sunny morning it feels like a quick jaunt with a great view.

Also, the bridge isn’t just one straight line from curb to curb. It has approaches, ramps, and connections that add to the total length. So the 9,650-foot figure includes all the practical stuff that gets you on and off the bridge.

That’s why you might see slightly different numbers depending on the source. Some measurements focus on the suspension structure, others on the whole crossing. But for everyday conversation, 9,650 feet is the gold standard.

Fun Comparisons

The bridge is about 18 football fields long, if you count end zones. It’s also roughly 30 times the height of a giraffe, which is a totally normal way to measure a bridge. And it’s about 1.83 miles, which is shorter than the Las Vegas Strip but longer than a really ambitious coffee run.

You could listen to about five average pop songs while walking across. Or one long prog-rock epic, if that’s your thing. The bridge doesn’t judge.

The Short Answer and the Long Answer

Short answer: the Benjamin Franklin Bridge is 9,650 feet long, or about 1.83 miles, with a 1,750-foot main span and 385-foot towers. It opened in 1926.

Long answer: it’s a 1.8-mile connection between two cities, two states, and a whole lot of history. It carries cars, trains, bikes, and people who just want to see the river from up high. It’s a landmark, a commute route, and a pretty great place to watch the sunset.

So the next time you’re near Philadelphia or Camden, give the Ben Franklin Bridge a little nod. It’s been doing its job for nearly a century, and it’s still one of the coolest ways to cross the Delaware. Whether you drive, walk, or just admire it from afar, that 1.83-mile stretch has a way of making the world feel a little more connected.

And honestly? That’s a length worth celebrating. So go take a walk, snap a photo, and enjoy the view. The bridge will be there, holding up traffic and holding together two great cities—one foot at a time.
