Extended N1 construction expected to impact traffic through northern Pretoria

Motorists travelling along the busy N1 corridor between the Proefplaas Interchange and the Pumulani Main Line Toll Plaza will have to endure prolonged construction activity after the R276-million rehabilitation project was officially extended to March 2027.

The project, led by Bakwena Platinum Corridor Concessionaire and awarded to Roadmac Surfacing, began in August 2025 and was initially expected to be completed by November this year.

Bakwena spokesperson Charmaine van Wyk confirmed that the project is currently about 30% complete, with additional remedial work identified during construction.

“During the rehabilitation work, we identified a need for additional remedial patching on the right-hand lanes to ensure the long-term structural integrity of the route.

To accommodate this essential work without compromising quality, the project timeline has been extended by four months, with a new anticipated completion date of March 2027, dependent on favourable weather conditions,” she said.

The 15-month contract forms part of Bakwena’s broader N1/N4 rehabilitation programme and focuses on restoring the structural strength of the road, improving driving conditions, and extending its lifespan in line with international engineering standards.

The scope of work includes the rehabilitation of the slow lanes in both northbound and southbound directions, upgrades to the Stormvoël and Zambezi interchanges, and sections of the Proefplaas Interchange.

Van Wyk said an asphalt overlay across the entire road surface is also planned, alongside the replacement of road signage and repairs to concrete-lined drainage systems.

These include partial reconstruction of the N1 northbound left-hand lane, extensive patching work at the Proefplaas and Stormvoël interchanges, and significant progress on drainage systems to improve water runoff.

Van Wyk added that infrastructure upgrades are also underway.

“We have commenced refurbishment of gantries and replacement of road signage to ensure structural safety and improved traffic safety.

“The final overlay of the entire length of the remedial works is scheduled to begin shortly,” she said.
