US 59 crash at Chimney Rock; 36 incidents in 30 days

A major crash shut down the southbound US 59 entrance ramp at Chimney Rock early Sunday morning, backing up traffic and forcing crews to divert vehicles around the scene.

The wreck happened at 2:58 AM on Sunday, August 30, 2026, at Exit 123 on the southbound side. The ramp was completely blocked as responding officers worked to clear the debris and reopen the roadway. With clear skies and temperatures in the low 80s, weather wasn't a factor in this one.

What's striking about this crash is where it happened. According to LocalTrafficAccidents.com data, the US 59 corridor at Chimney Rock has recorded 36 total incidents over the past 30 days—21 of them major crashes like this one. Over the past 90 days, the location has seen 143 total incidents, 70 classified as major. In the past 12 months, this spot alone has logged 332 incidents with 161 major crashes and 4 fatalities. That's not a one-off bad morning; it's a persistent pattern.

The timing of this particular crash—just before 3 AM on a Sunday—puts it outside the typical weekday rush-hour window. But the corridor itself doesn't follow standard commute patterns. According to LTA data, the busiest single hour at this location is 1 to 2 PM, when it recorded 19 crashes over the analysis period. Mondays historically see the most incidents here, with 25 crashes logged in recent 90-day windows.

Looking at the bigger picture, Texas Department of Transportation public crash records show 1,332 crashes within about a quarter-mile of this interchange since January 2020—a grim reminder that this is one of the state's most active crash zones. Contributing factors as recorded by the investigating officer, per TxDOT CRIS, show "Failed To Control Speed" as the leading factor, cited in 539 crashes at this corridor. The hit-and-run rate here runs 12.0 percent—346 of 2,891 involved units left the scene without exchanging information.

Drivers heading into the corridor should expect residual impacts through the early morning hours. The ramp was expected to reopen once the roadway was cleared, but backups likely persisted as traffic filtered back into normal flow. If you're planning to use US 59 southbound near Chimney Rock during daylight hours, give yourself extra time—this stretch runs hot even on a Sunday afternoon.
