N1 Closed Near Colesberg Due to Hazmat Incident – Alternative Routes Provided

A significant road closure is currently in effect on the N1 between Colesberg and Hanover following a hazardous materials (hazmat) incident early this morning. At approximately 05:50 AM on 2 July 2025, a truck transporting gas bottles overturned after the driver lost control while attempting to avoid an oncoming vehicle.

This caused a gas leak, and emergency services were dispatched to the scene immediately. The situation remains dangerous, and the road is expected to remain closed for the entire day as the hazardous materials are being managed.

Emergency Medical Services (EMS) arrived on the scene at 06:35 AM, and three male individuals, classified with serious injuries, were attended to. All the other relevant authorities are on site, ensuring safety and managing the recovery process.

Due to the dangerous nature of the hazardous material involved, no towing has yet taken place. A Hazmat service provider has been called in for a proper cleanup.

In light of the closure, alternative routes are being recommended for truckers and motorists.
