faqs[5]{q,a}:
  How far is Marietta to Atlanta?,About 20 miles downtown to downtown. Free-flow is 25–30 minutes. Weekday peaks run 50 minutes to 1 hour 10 on I-75 into the Downtown Connector. Pattern estimates, not live times.
  When is the worst time to drive Marietta to Atlanta?,Southbound into Atlanta 6:30–9:30 a.m. and northbound toward Marietta 3:00–7:00 p.m. Atlanta’s evening peak starts around 3 p.m. and does not clear until after 7.
  Does MARTA go to Marietta?,No. Cobb County is outside the MARTA rail network. CobbLinc buses connect parts of Cobb to MARTA stations. A common hybrid is drive to a northern MARTA station, then ride into downtown.
  Does a Braves game change the drive?,Yes. Truist Park at Cumberland sits on this corridor. Game days generate substantial I-75 traffic in a two-to-three-hour window before first pitch.
  Is this the same as Marietta to the airport?,No. Hartsfield-Jackson is south of downtown; Marietta is northwest. That is about a 30-mile crossing, not this 20-mile downtown run, and I-285 often enters the decision.
