IH-69 Southwest crash at Chimney Rock in rain; 79 incidents in 30 days

A crash on IH-69 Southwest southbound at Chimney Rock Road shut down lanes just after 12:31 AM Wednesday, June 17, backed up southbound traffic in moderate rain. Responding officers cleared the roadway, but the incident underscores an ongoing pattern at this location: according to LocalTrafficAccidents.com data, the corridor has logged 79 incidents over the past 30 days—52 of them major.

The timing caught drivers outside the typical weekday commute crush. Most crashes here fall outside rush hour peaks, though the single busiest hour is 3–4 PM, when the corridor sees roughly 20 crashes. This particular incident arrived in the pre-dawn darkness with wet pavement conditions that increase crash risk. TxDOT reports wet conditions contributed to over 14,000 Texas crashes in the most recent annual reporting period.

The scale of incidents at this stretch is significant. Looking back further, LTA data shows 242 total incidents in the past 90 days at IH-69 Southwest at Chimney Rock, with 169 classified as major. Since January 2020, the corridor within about a quarter-mile has recorded 1,543 crashes, per TxDOT CRIS public crash records.

If you were heading south on I-69 Southwest, crews advised using US-59 frontage roads, Hillcroft or Fondren for southwest segments, or SH-288 as alternates while the incident was being cleared. The roadway was open and traffic returning to normal flow by the time the morning commute began in earnest, but the pre-dawn crash adds to a corridor already running well above typical incident density.
