Anyone who has passed through the junction of I-85 and I-285, just Northeast of Atlanta, during rush hour knows to avoid doing that next time, if at all possible. For the third year running, "Spaghetti Junction", as it is both affectionately and derisively known, lands at the top of the American Transportation Research Institute's "Top 100 Truck Bottleneck" list.
Using GPS data from over 600,000 vehicles, they determined that the average speed through the interchange is around 38 mph, dropping closer to 20 mph during peak rush hour.
The study is done every year by the ATRI, to identify the cost of heavy traffic congestion on U.S. highways. According to this year's "Top Truck Bottlenecks" brochure, total monetary cost of highway congestion is some $49.6 billion, based on 728 million lost hours of productivity.
"Georgia Department of Transportation spokesperson Natalie Dale says they know this is a congested area and plans are in place to ease traffic flow."
Speaking from personal experience, Natalie, "Spaghetti Junction" doesn't really seem to have changed much in the past 25 years, at least. Back when traveling the 7 miles to work through the junction and surrounding thoroughfares normally took around 40-45 minutes by car, but could be done in 25 on a bicycle, still having time to stop for a microwave breakfast sammie at the QuikFill. You know what I'm talking about.
Atlanta is not the only home to a "Spaghetti Junction", however, with dozens of complicated interchanges, both in the U.S. and around the world, having been given the nickname.
