Motorists are notified of a temporary closure of the N4 Highway between the Simon Vermooten and Solomon Mahlangu interchanges, east of Tshwane, on Sunday, 15 June 2025, to allow for critical infrastructure work. This is a collaborative activity between the City of Tshwane Energy and Electricity Department, the South African National Roads Agency (SANRAL) and the Tshwane Metro Police Department (TMPD).
The closure is essential to facilitate the safe stringing of high-voltage conductors as part of the 300 MVA Waltloo–Njala transmission line project. This strategic infrastructure upgrade is crucial for strengthening and stabilising electricity supply to the eastern grid of Tshwane, benefiting residential and industrial zones below for the details of the closure:
- Date: Sunday, 15 June 2025
- Time: 08:00 to 17:00
- Affected route: N4 Highway in both directions between the Simon Vermooten and Solomon Mahlangu interchanges
In summary, the planned construction will entail the following aspects:
- High-voltage conductors will be strung across the N4 Highway using tension equipment.
- Conductors will maintain a minimum clearance height of 23 m above the roadway, in full compliance with safety standards.
- Transmission masts have been pre-approved and are located outside the road reserve.
- Detour routes and temporary signage will be clearly marked.
- TMPD officers will be on-site to manage and direct traffic.
The City of Tshwane apologises for any inconvenience caused and appreciates the public’s understanding as we work to enhance the city’s energy infrastructure.
