Highway 79 in Round Rock has been reopened following a hazardous spill on Wednesday evening that caused significant traffic delays. The Round Rock Fire Department and Williamson County HAZMAT teams responded to the incident near the Dairy Queen just east of I-35 after a 275-gallon container of kerosene fell from a vehicle, according to official reports.

The spill initially shut down the roadway from the I-35 frontage road to Mays Street. Motorists were advised to steer clear of the area while emergency crews worked to determine the contents of the container; one individual was evaluated on scene after inhalation exposure. According to updates from local authorities, there were temporary symptoms such as headaches or respiratory irritation caused by kerosene vapors could be, but air quality monitoring confirmed no ongoing risk to the public.

In a statement obtained by the Round Rock Texas government website, it was confirmed that "Testing on scene has confirmed the material was kerosene." In the wake of the accident, fire crews have efficiently contained the hazardous material, and the Texas Department of Transportation (TxDOT) has been brought in to manage the cleanup operation.

The incident, which unfolded in the 500 block of West Palm Valley Blvd., prompted an urgent response from the city's public safety personnel. They are continuing in monitoring the situation, ready to provide updates as the incident develops further. Any citizens having been in the immediate vicinity during the spill should seek fresh air and medical attention should their symptoms worsen, the Round Rock government website advises.

As Thursday morning traffic resumes its normal flow, the reopening of the roadway marks a swift turnaround from last night's emergency. The collaborative efforts of the local fire department and HAZMAT teams ensured the safety of the neighboring communities, effectively mitigating what could have been a more severe public health risk.
