A motor vehicle incident closed the southbound US 59 inbound-to-IH 610 inbound ramp at Chimney Rock at 6:16 AM on Monday, May 04, 2026. The incident was classified as major severity.
The crash occurred at a location that has become a consistent source of traffic disruption in Harris County. According to LocalTrafficAccidents.com data, the US 59 southbound-to-IH 610 inbound ramp at Chimney Rock intersection recorded 35 incidents over the past 30 days—a rate that places it in the extreme category for corridor heat. Over the same 30-day window, one fatal incident occurred at this location.
The broader pattern is more severe when viewed across a longer timeframe. In the past 90 days, LTA data shows 155 total incidents at this corridor, including 74 major incidents and 4 fatal crashes. Over a 12-month period, the location has recorded 158 total incidents with 75 major and 4 fatal.
Rush hour traffic carries particular weight at this location. Forty-six percent of the 90-day incident count at this ramp occurred during morning and evening peak hours, indicating that commuter volumes correlate with higher incident frequency. The peak crash hour across the 90-day window was 4 PM to 5 PM, which recorded 17 incidents. Tuesdays have been the highest-incident day over 90 days, with 23 recorded incidents.
Monday's 6:16 AM incident, however, fell outside the typical peak crash window at this location. The dominant incident pattern at this ramp is offpeak, suggesting that non-rush-hour periods also carry significant risk.
Weather conditions at the time of the incident were clear, with a temperature of 64°F.
Harris County recorded 19,108 total incidents in the past 30 days, including 39 fatal crashes, according to LTA tracking across the 13-county Houston-Galveston region.
The incident's impact on the inbound-to-inbound ramp connection during the morning commute window added to congestion on a corridor already marked by high incident frequency. The specific nature of the ramp configuration—a freeway-to-freeway connection—limits alternate routing options during blockages.
LTA tracks approximately 68,456 incidents across the 13-county region with updates every two minutes. Additional incident data is published annually by TxDOT through the CRIS (Crash Records Information System) database.
