Mist conditions at the time of the incident (76°F) may have been a factor. TxDOT reports wet conditions contributed to over 14,000 Texas crashes in the most recent annual reporting period.
The crash closed northbound lanes and diverted traffic. Drivers were advised to use the Hardy Toll Road, SH-249 (northwest approach), or local routes via Airline Drive as alternates.
