ATRI analysts examined 250 “freight-significant” highway areas using truck position and speed data, which was gathered from the wireless onboard communications systems often used by the trucking industry.
Analysts then compiled a “total freight congestion value” for each area based on average truck speed, hourly congestion and other relevant metrics.
They found that Atlanta’s Spaghetti Junction had an average speed of 38 miles per hour, but around 5-6 p.m., speeds averaged only 15-20 miles per hour.

Atlanta's I-75 and I-285 intersection also made the cut for ATRI's 100 worst bottlenecks at No. 9, up three spots from 2016.
And the I-20 and I-285 intersection ranked No. 14, up 12 spots from 2016.
Here are the five worst freight bottlenecks in America:
- Atlanta, Ga.: I-285 at I-85 (North) GA
- Fort Lee, N.J.: I-95 at SR 4
- Chicago, Ill.: I-290 at I-90/I-94
- Louisville, Ky.: I-65 at I-64/I-71
- Cincinnati, Ohio: I-71 at I-75
