Atlanta Beltline

12 min read

Imagine a city that grew up around railroads, became choked by them, and then watched them slowly die—only to realize decades later that those abandoned tracks might be the key to stitching itself back together. That's the story of Atlanta and its Beltline, a twenty-two-mile loop of trails, parks, and (eventually) transit that's attempting something cities rarely manage: turning a liability into an asset, and doing so in a way that actually serves the people who were most harmed by the original infrastructure.

How Atlanta Got Its Belt

To understand the Beltline, you have to understand what Atlanta was—and what it became after the Civil War.

Unlike most of the American South, which remained agricultural well into the twentieth century, Atlanta industrialized rapidly during Reconstruction. Factories sprouted. Workers flooded in. The city's population exploded. And all of this activity depended on railroads—the same railroads that had made Atlanta a strategic target during the war and led General Sherman to burn much of it to the ground.

The problem was simple: too many trains, not enough track. Downtown Atlanta became a railroad bottleneck. Every factory shipment, every passenger train, every freight car had to squeeze through the same congested central corridors. The solution, proposed in the late nineteenth century, was elegant in concept: build a "belt" of railway around the city center, allowing trains to bypass downtown entirely.

This belt took about thirty years to complete, and it wasn't built as a single coordinated project. Instead, four separate railroad companies constructed four separate segments that eventually connected into a rough circle. The Atlanta and Richmond Air-Line Railway built the northeastern section in the 1870s. The Seaboard Air Line Railroad—confusingly named, since it had nothing to do with aviation—completed its portion in 1892. The Atlanta and West Point Belt Line Railroad added its segment in 1899. And the Louisville and Nashville Railroad filled in the final gap by 1902.

The earliest known official reference to an Atlanta "belt line" appears on an 1888 geological survey map, which labels a railway segment as the "Belt Line R.R." and marks a junction point as "Belt Junction." That name would lie dormant for more than a century before being revived for something entirely different.

The Decline and the Dream

Railroads built Atlanta. Then highways nearly killed them.

As trucks replaced trains for freight and cars replaced trains for passengers, the belt railways slowly fell into disuse. One by one, the lines shut down. The Atlanta and Richmond Air-Line Railway ceased operations in the 1990s. The Atlanta and West Point Belt Line Railroad ran its last train in May 2014. The Louisville and Nashville segment likely stopped running in the mid-1980s, though records are scarce. Only one of the original four lines—the Seaboard Air Line, now owned by CSX—remains active today.

What was left behind was a ring of urban decay: rusting tracks, overgrown rights-of-way, abandoned industrial buildings, and the neighborhoods that had grown up alongside the railways—often poor, often Black, often deliberately cut off from wealthier parts of the city by those same tracks and by the highways that followed.

The idea of turning this ring of blight into a ring of parks first emerged in 1991, when the Georgia Rails-to-Trails Conservancy proposed converting the abandoned corridors into trails. Two years later, city planner Alycen Whiddon championed a similar concept, which Atlanta's City Council adopted as part of a fifteen-year parks plan.

But the vision that would eventually become the Beltline came from a graduate student named Ryan Gravel.

A Thesis That Changed a City

In 1999, Ryan Gravel was pursuing dual master's degrees in architecture and city planning at Georgia Tech. For his thesis, he proposed something ambitious: using the old railway belt not for trails or parks, but for transit. He envisioned a light-rail loop circling Atlanta's core, connecting neighborhoods that had been isolated for decades.

The thesis sat on a shelf for a year. Then, in 2000, Gravel was working at an Atlanta architectural firm when he and two colleagues—Mark Arnold and Sarah Edgens—decided to dust it off. They expanded his transit-only concept to include the trails and parks from the earlier proposals, wrote up a summary, and mailed copies to two dozen influential Atlantans.

Most of those copies probably went straight into recycling bins. But one landed on the desk of Cathy Woolard, then a member of Atlanta's City Council.

Woolard became a believer. She, Gravel, Arnold, and Edgens spent months promoting the idea to neighborhood groups and business leaders. They formed a nonprofit called Friends of the Belt Line. And when Woolard became City Council president, she convinced Mayor Shirley Franklin to support the project.

There was a catch, though. A series of feasibility studies, including a landmark report called "The Beltline Emerald Necklace" commissioned by the Trust for Public Land, concluded that Gravel's transit vision—while compelling—should come last, not first. The studies recommended tackling trails, parks, affordable housing, and zoning changes before laying any rail. In 2005, Atlanta's City Council adopted a Beltline Redevelopment Plan reflecting these priorities.

The transit piece would have to wait. It's still waiting.

What the Beltline Actually Is

The Atlanta Beltline, as it exists today and as it's planned for the future, is not one thing but several overlapping projects.

The most visible element is the trail system. When complete, it will include twenty-two miles of mainline trail forming a continuous loop around Atlanta's core, plus an additional eleven miles of spur trails connecting to surrounding neighborhoods. That's thirty-three miles of multi-use paths for walking, running, cycling, and rollerblading. As of mid-2024, about eleven miles of the mainline and ten miles of spurs are finished.

The second element is parks. The Beltline plan calls for creating or renovating thirteen hundred acres of green space—an increase of nearly forty percent in Atlanta's total parkland. The Trust for Public Land partnered with the project to acquire thirty-three properties for this purpose. These parks aren't random patches of grass; they're conceived as an "Emerald Necklace" of green jewels connected by the trail system.

The third element—the one that existed only in Ryan Gravel's thesis for years—is transit. The original vision called for streetcars running the full loop. Since 2016, when Atlanta voters approved a sales tax increase known as "More MARTA," the Metropolitan Atlanta Rapid Transit Authority has been working with the Beltline on transit planning. But no light-rail lines have been built yet.

Instead, the first transit connection will be bus rapid transit—often abbreviated BRT, a system that uses dedicated lanes and station platforms to make buses operate more like trains. The MARTA Rapid Summerhill line, currently under construction, will run five miles from downtown Atlanta through the Summerhill neighborhood to the Beltline. It's scheduled to open in late 2025, using sixty-foot articulated electric buses.

The Trail Takes Shape

The first piece of trail opened in 2008: a 2.4-mile segment called the West End Trail, running from White Street to Westview Cemetery. It wasn't built on the old railroad right-of-way; instead, it edges along city streets through the West End neighborhood, serving Mozley Park and Westview.

The Eastside Trail came next and quickly became the Beltline's showcase. Stretching from Piedmont Park down through the Old Fourth Ward and Inman Park neighborhoods, it passes through the densest concentration of repurposed industrial architecture in Atlanta. Warehouses have become apartments. Factories have become offices. The most dramatic transformation is Ponce City Market, a former Sears distribution center that now houses restaurants, shops, offices, and a rooftop carnival.

The Westside Trail, which opened in September 2017 after receiving an eighteen-million-dollar federal grant in 2013, runs 3.2 miles through the old railroad corridor from West Marietta Street to Interstate 20. Parts of the West End Trail run parallel to it, just outside the rail corridor—a quirk of the piecemeal development process.

Other segments are in various stages of completion. The Southside Trail will eventually extend 2.4 miles; a portion linking to the Southwest Trail near Pittsburgh Yards is finished. The Southeast Trail, planned for 2.5 miles, has a completed section running from near Krog Street Tunnel through Reynoldstown. The Northside Trail has sections open in the Collier Hills area and Tanyard Creek Park, with plans to eventually connect to the Peachtree Creek Greenway and PATH400.

The ambition is audacious. When the Beltline connects to the Silver Comet Trail—a ninety-mile path running west toward the Alabama border—and to PATH Foundation's other regional trails, the combined network will total about three hundred miles. That would make it the longest paved trail system in the United States.

The Gaps That Won't Close Easily

A loop is only a loop if it connects. Right now, the Beltline has five gaps where rights-of-way don't meet, where active rail lines block the path, or where highways create seemingly unbridgeable barriers.

The most challenging is near Maddox Park in the Bankhead area, where one of the busiest rail corridors in Georgia cuts directly across the planned route. Proposals include taking the trail east to cross under Hollowell Parkway, diverting through private property at Marietta Boulevard, or simply sharing the road with vehicle traffic on Lowery Boulevard.

Near the Lindbergh Center MARTA station, the Armour Yards gap is bisected by two active rail lines. The proposed solution involves the trail following Clear Creek around a warehouse complex, then tunneling under the active tracks and Interstate 85 to reach Ansley Golf Course before rejoining the mainline.

The CSX Hulsey Yard, near the Inman Park/Reynoldstown MARTA station, presents another obstacle. Here, the workaround is elegant: use the existing tunnel at Krog Street, a graffiti-covered passage that has become one of Atlanta's most distinctive urban spaces.

Bill Kennedy Way, also known as the Glenwood-Memorial Connector, requires widening an existing bridge over Interstate 20 to accommodate trail, transit, and motor vehicle traffic simultaneously. And near the Ashby MARTA station, the gap between Washington Park and Joseph E. Boone Boulevard might be solved by spanning over the MARTA tracks or sharing the right-of-way.

These aren't just engineering problems. They're political problems, funding problems, negotiation problems. They're the reason the Beltline's planners estimated in 2014 that they had seventeen years of work ahead of them—and why the current completion target is 2030.

The Emerald Necklace

The parks being created or renovated along the Beltline range from pocket parks of two acres to major green spaces that rival the city's most famous destinations.

Historic Fourth Ward Park, at sixty-three acres, sits near Ponce City Market and includes an innovative stormwater management system that doubles as a scenic water feature. D.H. Stanton Park, at eight acres in the Peoplestown neighborhood, became Atlanta's first energy-cost-neutral park. Maddox Park encompasses fifty-one acres near the difficult Bankhead gap.

But the crown jewel—quite literally, in the Emerald Necklace metaphor—is Shirley Clarke Franklin Park, named after the mayor who championed the project. At 351 acres, it will be roughly twice the size of Piedmont Park, Atlanta's beloved urban green space that most visitors assume is the city's largest. Franklin Park is being built on the site of the former Bellwood Quarry, a hundred-foot-deep former gravel pit that will become a reservoir serving as both water storage and scenic centerpiece.

Waterworks Park will add another 204 acres. Ardmore Park, 114 acres. Peachtree Creek Park, sixty-five acres near Buckhead. When complete, these parks will transform Atlanta from a city that grudgingly maintained some green space into one where nature genuinely weaves through the urban fabric.

The Promise and the Peril

The Beltline's stated goals are ambitious: reconnect neighborhoods divided by infrastructure, improve transportation, add green space, promote redevelopment, create affordable housing, and showcase arts and culture. The tension in that list is obvious to anyone who has watched urban revitalization projects unfold elsewhere.

Reconnecting neighborhoods and adding green space tends to promote redevelopment. Redevelopment tends to increase property values. Increased property values tend to displace the very residents who were "historically divided and marginalized by infrastructure" in the first place. Creating affordable housing becomes harder, not easier, as land values rise.

This isn't a hypothetical concern. The neighborhoods along the Eastside Trail—the Beltline's most complete and celebrated section—have experienced dramatic gentrification. Long-time residents have been priced out. Businesses that served working-class communities have been replaced by expensive restaurants and boutiques. The trail is beautiful. The Ponce City Market is genuinely delightful. But the people who lived in those neighborhoods for decades when no one else wanted to are increasingly not the people enjoying these amenities.

The Beltline's planners are aware of this dynamic. Affordable housing is explicitly part of the mission. But awareness and achievement are different things, and the forces driving displacement are powerful.

A City Betting on Itself

The Atlanta Beltline is, at its core, an act of civic imagination: the idea that abandoned infrastructure could become the backbone of a different kind of city, one where walking and biking are viable, where neighborhoods connect instead of being severed, where industrial blight becomes parks and gathering spaces.

It's also an enormous bet. The original transit vision remains largely unrealized after two decades. The completion date has slipped repeatedly. The gaps in the loop present genuine engineering and political challenges. And the tension between revitalization and displacement has no easy resolution.

But the portions that are built are remarkable. On any given weekend, the Eastside Trail is packed with joggers, cyclists, families with strollers, couples walking dogs, tourists snapping photos, and locals grabbing coffee at converted industrial buildings. The West End Trail and Westside Trail bring the same amenities to parts of Atlanta that rarely received such investment. The parks are being built, the connections are slowly being made, and a city that spent a century tearing itself apart with highways and railways is trying to use those same corridors to knit itself back together.

Whether Atlanta succeeds—and for whom—remains to be seen. But the attempt is worth watching, and the question it poses is worth asking: What could your city build on the infrastructure it abandoned?
