The large-scale rehabilitation project of the N1 between the Proefplaas interchange and the Pumulani Mainline Toll Plaza will be completed in March 2027. The project was originally launched in August 2025, at a cost of R276 million, and scheduled for completion in late 2026.

However, additional works were incorporated to address underlying road surface issues, costing an additional R35 Million, and increasing the total rehabilitation cost to R311 million. This will also mean extending the completion date.

Bakwena Platinum Corridor Concessionaire in their mid-year progress update said the upgrade is vital to maintaining a safe, reliable, and efficient transport link for thousands of daily commuters and freight operators.

What the Project Covers

The rehabilitation works include:

• Rehabilitation of the base layer in the slow lanes in both directions.
• Surface repairs at the Stormvoël and Zambezi interchanges, plus targeted improvements at the Proefplaas Interchange.
• A full asphalt overlay across both the slow and fast lanes in both directions.
• Replacement of outdated road signage and repairs to concrete-lined drainage systems.

Work is being carried out during both daytime and nighttime shifts, with temporary lane closures in both directions. To date, more than 22 000 tons of asphalt have been laid during night shifts (19:00–06:00).

From mid-July, asphalt overlay works will begin, requiring temporary lane closures on certain interchange ramps, including Proefplaas.

Minimising Disruption

Bakwena has implemented strict traffic management measures to keep travel safe and reduce delays, with a focus on minimising temporary lane closures during peak travel times as much as possible, the majority of the repairs have been scheduled for night-shift works.

Long-Term Benefits

Once complete, the project will deliver smoother, safer journeys, improved freight efficiency, and stronger regional trade links. It is also creating local jobs and supporting small businesses through local supplier participation.
