Is Marietta Considered Part of Atlanta?

Marietta is its own city and the county seat of Cobb County, but it’s widely considered part of metro Atlanta. Many people:

  • Live in Marietta and commute to jobs in Atlanta
  • Travel frequently between the two for sports games, shopping, dining, and events
  • View Marietta as the northwest suburban hub of the Atlanta area

If you’re staying in Atlanta, visiting Marietta often feels like going to a close-by neighborhood rather than a far-off town.

Public Transportation Between Atlanta and Marietta

While Atlanta and Marietta are close, they’re served by different transit systems:

  • MARTA (Metropolitan Atlanta Rapid Transit Authority) mainly covers Fulton and DeKalb counties (including most of Atlanta).
  • CobbLinc serves Cobb County, including Marietta.

You can still travel between Atlanta and Marietta using a combination of MARTA and CobbLinc.

1. Using MARTA + CobbLinc

A common way to get from Atlanta to Marietta without driving:

  1. Take MARTA rail or bus to a station near the Cobb County line, often:

    • Arts Center Station (MARTA rail, Midtown)
    • Civic Center Station or North Avenue Station can also work depending on your route
  2. Transfer to CobbLinc (usually at designated stops or bus transfer points). CobbLinc routes connect to key areas in Marietta, including near Marietta Square.

CobbLinc information is generally available through:

  • CobbLinc Customer Service: often reachable via county transportation lines
  • Main transit points near Marietta include the Marietta Transfer Center close to downtown Marietta.

🚌 Tip: Schedules for MARTA and CobbLinc may not always line up perfectly. Build in buffer time, especially for evening or weekend trips.

2. Park-and-Ride Options

Many Atlanta-area commuters who live or work in Marietta use:

  • Park-and-ride lots along I‑75 or I‑285
  • Carpool and vanpool programs offered through regional transportation agencies

These options can reduce drive time stress and parking costs if you’re going back and forth frequently.

Ride-Sharing, Taxis, and Private Shuttles

If you don’t want to drive or deal with transfers:

  • Ride-share services (like app-based car services) regularly operate between Atlanta and Marietta.
    • Travel time is similar to driving yourself, but you avoid parking.
  • Taxi services and some private shuttle or car services also cover this corridor, especially for:
    • Airport trips from Marietta hotels or residences
    • Event transportation (for example, from Downtown Atlanta to the Truist Park area, which is just southeast of central Marietta)

Costs can vary widely based on traffic, time of day, and surge pricing, but the distance of 18–35 miles usually places the fare in a mid-range for local trips.

What Affects Travel Time Between Atlanta and Marietta?

Even though the distance is relatively short, several Atlanta-specific factors affect how fast you can get between the two cities.

1. Rush Hour

Morning rush (about 6:30–9:30 a.m.) and evening rush (about 3:30–7:00 p.m.) can cause:

  • Slowdowns on I‑75 North and South
  • Heavy congestion near the Downtown Connector, I‑285 interchange, and Cumberland/Truist Park area

2. Events and Game Days

You may see extra traffic when:

  • The Atlanta Braves are playing at Truist Park (near I‑75/I‑285, just southeast of Marietta)
  • Major concerts or events are happening at State Farm Arena, Mercedes-Benz Stadium, or Cobb Galleria Centre

On these days, it may take significantly longer than usual to get between Atlanta and Marietta, especially in the late afternoon and evening.

3. Weather and Road Incidents

Atlanta is known for:

  • Heavy rainstorms that can slow traffic and reduce visibility
  • Occasional winter weather issues that can cause major delays
  • Crashes or stalled vehicles on I‑75 or I‑285 that can quickly back up traffic

Checking a traffic app or local traffic reports before you leave can prevent unexpected delays.

When Does It Make Sense to Stay in Marietta vs. Atlanta?

Because the distance is relatively short, many visitors to Atlanta choose hotels in both cities depending on their plans.

You might want to stay in or near Marietta if:

  • You’re attending events or games near Truist Park or Cobb Galleria Centre
  • You plan to spend time around Marietta Square, Kennesaw Mountain, or other Cobb County attractions
  • You prefer a quieter, more suburban base while still accessing Atlanta

You might prefer to stay in Atlanta (Downtown, Midtown, or Buckhead) if:

  • Most of your activities are in central Atlanta (museums, major attractions, business meetings)
  • You plan to rely heavily on MARTA rail
  • You want to minimize driving and focus on walking or short rides within the city

Because the two cities are only about 20 miles apart, many visitors comfortably split their time between them in a single trip.
