You’ve probably driven past it on the Dames Point Bridge, looking down at that sprawling maze of cranes and thousands upon thousands of cars glittering in the sun. It’s Blount Island. Honestly, most folks in Jacksonville just see it as a landmark on their commute, but if you look closer, it’s basically the heartbeat of the entire region’s economy.
Blount Island Jacksonville FL isn’t just some random plot of land in the middle of the St. Johns River. It’s a 2,000-acre powerhouse.
I’m talking about one of the largest vehicle import/export centers in the United States. If you’re driving a Toyota or a Mazda in the Southeast, there is a very high probability it touched the pavement at Blount Island before it ever reached your local dealership. But the island is undergoing a massive identity shift right now. It's moving away from just being "the car place" and turning into a deep-water titan capable of handling the biggest ships on the planet.
The $400 Million Face-Lift You Might Have Missed
For years, there was a ceiling on how much Blount Island could actually do. That ceiling was the riverbed.
The St. Johns River used to be about 40 feet deep. That sounds like a lot until you realize the new "Post-Panamax" ships—the massive vessels that started coming through the expanded Panama Canal—need way more room. If those ships can't get in, the cargo goes to Savannah or Charleston instead. Jacksonville wasn't about to let that happen.
The JAXPORT Harbor Deepening project was a literal game-changer. They dug that channel down to 47 feet. It was a brutal, expensive, and logistically insane project that wrapped up recently, and it effectively cleared the way for the world’s largest container ships to dock directly at the Blount Island Marine Terminal.
Why those seven feet matter
It’s not just about "bigger ships." It’s about weight. A ship that can sit deeper in the water can carry thousands of more containers. For a business, that’s the difference between a profitable voyage and a waste of fuel.
Because of this deepening, we’re seeing massive upgrades at the SSA Jacksonville Container Terminal. They’ve added these towering electric 100-gauge cranes. They look like something out of a sci-fi movie. These things can reach across ships that are 22 containers wide. When you stand under one, you really feel how small a human is in the grand scheme of global trade.

The Weird Geography of the Island
Blount Island is technically an island, but it doesn't feel like one when you're on it. It was created by the U.S. Army Corps of Engineers back in the day by depositing dredged material. It's an industrial Frankenstein.
You’ve got the public side, managed by JAXPORT, and then you’ve got the military presence. The Marine Corps Intermodal Logistics Logistics Base (BICF) is tucked away there too. It’s a high-security zone where the military pre-positions equipment for global crises. It’s kinda surreal to see rows of heavy-duty military vehicles right next to a shipment of pristine luxury sedans destined for a showroom in Orlando.
Natural barriers and the bridge
The Dames Point Bridge—officially the Napoleon Bonaparte Broward Bridge, but literally nobody calls it that—is the gatekeeper. It’s one of the largest cable-stayed bridges in the world. While the river was deepened, the bridge height is the next thing people whisper about. Currently, the "air draft" is about 175 feet. Most ships fit fine, but as the industry builds taller and taller, the bridge is the one fixed variable that keeps engineers up at night.
Blount Island Jacksonville FL: The Car Capital of the East Coast
If you want to understand the scale of what happens here, you have to talk about the cars. JAXPORT is consistently ranked as one of the top vehicle ports in the country.
Companies like AMPORTS operate massive facilities on the island. They don't just park the cars; they process them. When a ship carrying 5,000 SUVs arrives, it’s a choreographed dance of drivers known as "longshoremen" who move those vehicles off the ship with terrifying precision.
- Customization on-site: Did you know many cars get their finishing touches right there on Blount Island? They install floor mats, roof racks, and even leather interiors in specialized processing centers before the cars are loaded onto trucks or rail cars.
- The "Ro/Ro" Factor: In the industry, they call it "Roll-on/Roll-off." It’s the most efficient way to move heavy machinery. We aren't just talking about Kias. We are talking about massive Caterpillar excavators and agricultural equipment headed to South America.
- Space is premium: Every square inch of the island is accounted for. There are moments when the island is so full of vehicles that it looks like a solid sheet of metal from the air.
What Most People Get Wrong About the Environmental Impact
Look, you can't dig up a river and move millions of tons of cargo without people worrying about the manatees and the water quality. It’s a valid concern. The St. Johns River is a slow-moving, "lazy" river that flows north, which makes it sensitive to changes.
Critics of the harbor deepening often point to saltwater intrusion. When you make the channel deeper, saltier water from the Atlantic can push further upstream. This affects the cypress trees and the fish populations.

The compromise has been a series of massive mitigation projects. JAXPORT and the federal government have had to put up hundreds of millions of dollars to preserve land elsewhere and monitor water quality. It’s a constant tug-of-war between "we need jobs" and "we need a healthy river." Most local environmental groups like the St. Johns Riverkeeper keep a very close eye on Blount Island operations. They aren't always happy, but the dialogue is at least constant.
The Jobs Nobody Sees
When people think of port jobs, they think of "The Wire" or old-school dockworkers with hooks. It’s not like that anymore.
A huge chunk of the work at Blount Island is now tech-heavy. We're talking about logistics coordinators managing complex software that tracks every single container via GPS. There are specialized mechanics who only work on the massive cranes.
The port supports roughly 138,000 jobs in Florida. Not all of those people are on the island, obviously, but the island is the catalyst. Without the flow of goods through those gates, the warehouses in Westside Jacksonville and the trucking companies along I-95 would dry up overnight.
The Cruise Connection?
Actually, no. That’s a common mix-up. If you’re looking to get on a Carnival cruise, you’re going to the JAXPORT Cruise Terminal which is nearby, but not on Blount Island itself. Blount Island is the "workhorse." It’s gritty, industrial, and strictly business. You won't find any waterslides or buffet lines here.
Why the Future is Electric (and Automated)
If you visit Blount Island in 2026, you're going to see a lot more charging stations than you would have five years ago.
The maritime industry is under huge pressure to de-carbonize. JAXPORT has been snagging federal grants to swap out old diesel equipment for electric versions. The new cranes are electric, and there’s a massive push to get "shore power" at the berths. This allows ships to plug into the grid instead of idling their massive engines while they’re docked, which cuts down on the smog hanging over North Jacksonville.

There's also the automation shift. It's a touchy subject because of the labor unions (the ILA is very powerful here). While full automation is still a ways off, the "smart port" tech—using AI to predict where a container should be placed to minimize moving it twice—is already in play. It’s about efficiency. In the shipping world, time is literally millions of dollars.
Navigating the Logistics: If You're Doing Business Here
If you are a business owner looking to leverage Blount Island, you need to understand the "Foreign Trade Zone" (FTZ) status.
Basically, JAXPORT (including Blount Island) operates as FTZ No. 64. This is a huge deal for taxes. It allows companies to land cargo on the island, store it, or even process it without paying formal U.S. Customs duties until the product leaves the zone for the domestic market. If you re-export it, you might not pay those duties at all.
That’s why so many international companies are setting up shop in the industrial parks surrounding the port. You save on the "carry cost" of your inventory.
Actionable Insights for the Average Jacksonville Resident
Most people will never set foot on the secure parts of Blount Island. It’s walled off for good reason. But you can still engage with it in ways that matter:
- Watch the Ships: If you want the best view of the massive vessels coming into Blount Island, head to Fort Caroline National Memorial or St. Johns Boat Dock. The sight of a 1,200-foot ship navigating the narrow river turns is genuinely breathtaking.
- Job Opportunities: Don't just look at "JAXPORT." Look at the tenants. Companies like Ceres, SSA Marine, AMPORTS, and Crowley are the ones doing the actual hiring for logistics, terminal operations, and heavy equipment maintenance.
- Real Estate Impact: If you're looking to buy property in North Jacksonville or near the Heckscher Drive corridor, the activity at Blount Island is your biggest economic indicator. When the port grows, the demand for local housing for port workers and logistics managers spikes.
- Environmental Awareness: Support the St. Johns Riverkeeper. They are the primary watchdog ensuring that the industrial growth on the island doesn't come at the cost of the river's long-term health.
Blount Island is a strange, noisy, incredibly busy place that most of us just glance at from the window of our cars. But it’s the reason Jacksonville is a "logistics city" and not just another beach town. It’s the gate to the Atlantic, and right now, that gate is wider than it’s ever been in history.
The sheer volume of cargo expected to move through here in the next decade is staggering. As global supply chains continue to shift away from the West Coast and toward the East, Blount Island is perfectly positioned to catch that wave. It’s not just a piece of land in a river; it’s the future of Florida’s economy, hidden in plain sight.
