If you’re looking for the Port of Brunswick on a map, you’ll find it tucked into the southeast corner of Georgia, specifically in Glynn County. It’s not just some sleepy coastal dock. Honestly, it’s one of the most productive pieces of real estate on the Atlantic seaboard. You’ve probably driven past car haulers on I-95 without realizing they just came from here.
Most people confuse it with Savannah. That’s a mistake. While Savannah handles the massive steel boxes we call containers, Brunswick is the king of "Ro-Ro." That’s industry speak for Roll-on/Roll-off cargo. Basically, if it has wheels or tracks—think Kias, Hyundais, or massive John Deere tractors—it probably moves through here.
Where Exactly is the Port of Brunswick on a Map?
Open up Google Maps. Zoom into the Georgia coastline, right between Savannah and Jacksonville. You’ll see the city of Brunswick sitting on a peninsula, flanked by the East River and the Turtle River. The port itself isn't one single spot but is divided into three primary terminals: Colonel’s Island, Mayor’s Point, and Marine Port.
Colonel’s Island is the heavy hitter.
Located south of the city and west of the Sidney Lanier Bridge, this terminal is the heartbeat of the operation. It covers over 1,700 acres. That sounds like a lot, but when you’re staging 80,000 vehicles at a time, space disappears fast. The geography is perfect. It’s naturally sheltered but sits just a short hop from the open Atlantic. The shipping channel is deep—about 36 feet—and the Georgia Ports Authority (GPA) is constantly working to keep it that way.
The location matters for logistics. It’s sits right near I-95 and US-17. More importantly, it has direct Class I rail service from CSX and Norfolk Southern. If a car is manufactured in Tennessee or Kentucky and needs to get to Germany, it’s coming here.
Why the World’s Car Makers Obsess Over This Spot
You might wonder why companies like Mercedes-Benz, Volkswagen, and Toyota don't just use bigger ports in New York or Florida. It comes down to "dwell time" and processing. Brunswick is specialized. Unlike the chaotic, multi-purpose ports in the Northeast, Brunswick is a fine-tuned machine for vehicles.

They have dedicated "Auto Processors."
When a car rolls off a massive vessel at Colonel's Island, it doesn't just sit there. On-site companies like Wallenius Wilhelmsen Solutions (WWS) or BMW take the keys. They do the final inspections. They install floor mats, specialized tech packages, or those little window stickers you see at the dealership. It’s a factory-to-port-to-showroom pipeline that happens right there on the Brunswick map.
In 2023, the GPA moved over 775,000 units of Ro-Ro cargo. That isn't just a "good year." It’s a signal that Brunswick is on track to become the busiest auto port in the entire United States, potentially unseating Baltimore. The sheer volume is staggering. Think about a parking lot that never ends, where every single car is brand new and headed to a different zip code.
The Sidney Lanier Bridge: A Beautiful Obstacle
You can't talk about the port's location without mentioning the bridge. The Sidney Lanier Bridge is a stunning cable-stayed structure that carries US-17 over the South Brunswick River. It’s the tallest span in Georgia. For tourists, it’s a photo op. For harbor pilots, it’s the gateway.
Massive ships, some as long as two football fields, have to pass under this bridge to reach Colonel’s Island. These vessels, called Pure Car and Truck Carriers (PCTCs), look like giant floating shoeboxes. They are built for volume, not aesthetics.
Seeing one of these behemoths glide under the bridge is a lesson in precision. The clearance is roughly 185 feet at high tide. It looks tight. It feels tight. But it works. This vertical clearance is one of the reasons Brunswick stays competitive while other ports struggle with aging, low-slung bridges that block modern mega-ships.

Impact on the Local Economy and Environment
The port isn't just a bunch of concrete and steel. It’s the primary economic engine for the region. Around 1 in 11 jobs in Georgia are tied to the ports in some way. In Brunswick, that means thousands of people working as longshoremen, processors, truck drivers, and port police.
But it’s not all smooth sailing.
The Golden Isles—St. Simons, Sea Island, Jekyll Island—are right next door. This is an environmentally sensitive area with vast salt marshes. The tension between industrial growth and environmental preservation is real. The 2019 capsizing of the Golden Ray, a massive car carrier, was a wake-up call. It took two years to remove the ship, which sat on its side in the St. Simons Sound, leaking oil and spilling cars into the water.
Local groups like the Altamaha Riverkeeper keep a close eye on the port’s expansion. As the GPA adds more berths and paves more of Colonel’s Island, water runoff and habitat loss become major talking points in town hall meetings. It’s a balance. You want the jobs, but you also want to keep the marshes clean enough for the shrimp and crabs the area is famous for.
What’s Next for the Port?
The Georgia Ports Authority is pouring hundreds of millions of dollars into Brunswick. They aren't playing around. They recently finished a massive expansion of the "south side" of Colonel's Island, adding more processing space and a fourth Ro-Ro berth.
The goal? One million units a year.

They are also shifting all breakbulk cargo (like forest products and paper) to Mayor’s Point to leave Colonel’s Island exclusively for wheels and tracks. This specialization is their "secret sauce." If you’re a logistics manager in Tokyo or Stuttgart, you choose Brunswick because you know your cars won't get stuck behind a shipment of scrap metal or a mountain of salt.
Identifying the Port on Your Next Trip
Next time you're driving south toward Florida, don't just blink and miss it. Look for the cranes. Look for the towering Sidney Lanier Bridge.
If you want the best view of the action, head to the Liberty Ship Park or grab a spot near the pier on St. Simons Island. You can watch the PCTCs move in and out of the sound. It’s a slow, silent parade of global commerce.
Actionable Insights for Navigating the Port of Brunswick Topic:
- For Business Owners: If you are in the automotive or heavy machinery supply chain, look into the "Foreign Trade Zone" (FTZ) status of the Port of Brunswick. It can significantly reduce or defer customs duties on imported goods.
- For Job Seekers: Check the Georgia Ports Authority career portal directly. They don't just hire dock workers; they need IT specialists, environmental engineers, and logistics analysts.
- For Travelers: Avoid the Sidney Lanier Bridge during peak wind events or heavy fog. The port activity can sometimes cause localized traffic surges on US-17 when shifts change or large shipments arrive.
- For Real Estate Investors: Keep an eye on the "Brunswick-Glynn County" area. The port expansion is driving a need for warehousing and workforce housing, making the "upland" areas north and west of the port high-growth zones.
Understanding the Port of Brunswick on a map is about more than just coordinates. It’s about recognizing a focal point of the American economy. It’s where the world’s manufacturing meets the American road.
