Safety & known trouble spots
I-635 is repeatedly cited among Dallas's most crash-heavy highways. Reported crash counts, however, vary widely by source and by year, so specific totals should be read as public reports rather than settled figures. According to Dallas-area injury law firm reporting, the I-635 and Skillman Street area is one location repeatedly named as a hotspot.
The corridor's high traffic volumes and complex, multi-level interchanges — including a heavily reconstructed section on the west end — are the factors most often mentioned when explaining its crash reputation.
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.
