The implementation of these projects and trends reflects Atlanta’s commitment to improving traffic flow, enhancing safety, and creating a more efficient transportation ecosystem. For commuters, staying informed about these developments can lead to better navigation strategies and less time spent in gridlock.

Navigating Atlanta’s busy streets and highways can be challenging, especially during peak traffic hours. Below are some navigational tips that can help commuters, new residents, frequent travelers, delivery drivers, tourists, and local businesses make the most out of their time on the road.

Alternative Routes

Finding alternative routes can significantly reduce commute time and help avoid congested or accident-prone areas. Here are a few suggested routes:

  1. Surface Streets: Using surface streets instead of highways can often save time. Roads such as Piedmont Avenue and Moreland Avenue can be useful alternatives to major highways like I-85.

  2. Back Roads: Streets like Norcross-Tucker Road and Roswell Road can serve as alternative arteries to avoid heavy traffic on major routes.

  3. Perimeter Route: For those commuting to the suburbs, using the I-285 Perimeter can sometimes be faster than cutting through the city.

Traffic Hotspots to Avoid

Certain stretches of road are consistently congested and should be avoided whenever possible. The Atlanta Regional Commission gathered data on the most problematic areas (AJC). Here are a few traffic hotspots:

Location Average Duration Average Length Frequency
I-85/I-75 North at I-85/I-75 split 4 hours 5 minutes 3.7 miles 132 times
I-75 North at Chastain Road/Exit 271 2 hours 36 minutes 8.5 miles 113 times
Downtown Connector and I-20 at I-85/I-75 South 4 hours 15 minutes 3.2 miles 100 times
  1. I-85/I-75 Split: This section is notorious for long bottlenecks, with an average duration of over 4 hours. Avoid this area during peak hours whenever possible.

  2. I-75 North at Chastain Road/Exit 271: Known for being a particularly bad stretch, it records an average duration of over 2.5 hours.

  3. Downtown Connector and I-20 at I-85/I-75 South: Another major trouble spot with average congestion durations exceeding 4 hours. It’s best to plan alternate routes around this area.

By avoiding these hotspots and exploring alternative routes, you can increase your efficiency on the road and minimize the stress of navigating Atlanta’s traffic.
