Safety & known trouble spots
According to a widely-cited analysis, I-285 has ranked among the interstates with the highest fatal-crashes-per-mile in the country, with some reporting describing it as one of the deadliest. These characterizations come from law-firm and local analyses of crash data and should be read as public reports rather than official rankings.
The I-285 and I-85 interchange, nicknamed "Spaghetti Junction," is repeatedly named as a hotspot within the loop. Commentators frequently note that I-285 was originally built as a four-lane bypass in the late 1960s and was never designed for the volumes it now carries.
Heavy commuter and commercial-truck traffic, complex multi-level interchanges, and constant merging around the loop are the factors most often cited when explaining why the Perimeter sees so many reported crashes.
The claims above are drawn from the public reports and third-party analyses linked in Sources. We include them for context, not as official or settled rankings.
