Multi-Vehicle Collision Shuts Down M1 Northbound in Houghton Estate
A major traffic disruption occurred on the M1 Northbound before the Glenhove Road off-ramp in Houghton Estate on Sunday morning, 4 January 2026. The Johannesburg Metropolitan Police Department (JMPD) and emergency services were summoned to the scene following reports of a severe, multi-vehicle collision.
What Happened and Immediate Response
Early reports indicate that a multi-vehicle incident caused the M1 Northbound to be completely closed as first responders worked to secure the area, assist victims, and clear debris. The exact sequence of events is under investigation, but witnesses describe a chaotic scene with several vehicles involved and others forced to brake sharply to avoid a collision.
Traffic Management and Detours
Authorities have established detours to manage the peak-time traffic and minimize disruption to the surrounding roads. Commuters are advised to use alternate routes, including local arterials and parallel corridors, while the scene is being cleared and investigations proceed. Motorists should expect significant delays and plan for extended travel times.
Impact on Commuters and Local Access
The closure on the M1 Northbound affects a major corridor used by daily commuters, cargo transport, and emergency services. Businesses near the Glenhove Road interchange may experience temporary access issues, and residents in nearby Houghton Estate could see increased traffic on side streets as drivers seek alternate routes.
Statements from Officials
JMPD spokespersons stated that police units, along with medical teams and tow services, are on site. The priority is to attend to any injured parties and secure the crash area to prevent secondary incidents. Investigators will later examine vehicle positions, possible contributing factors, and any safety-system data from the involved cars and trucks.
Injuries and Casualties
There has been official confirmation of injuries; however, the full extent and severity are still being assessed. Victims have been transported to nearby hospitals for treatment. The public will be kept informed as authorized updates become available.
What Drivers Should Do Next
For those traveling in the area, monitoring live traffic updates is essential. Police remind drivers to slow down as they approach the scene from a safe distance and to adhere to instructions from first responders. If you have information about the crash, contact local authorities to assist with the investigation.
Looking Ahead
As investigations unfold, authorities will work to determine the causes of the crash and implement any safety measures to prevent a recurrence on one of Johannesburg’s busiest routes. The M1 Northbound re-opening timeline will depend on the progression of the clearance and evidence collection. Updates will be provided as the situation develops.
