Temporary road closures on N3 westbound carriageway for bridge upgrades

The South African National Roads Agency SOC Limited (SANRAL) has announced a series of temporary road closures on the N3 Westbound Carriageway at the Paradise Valley interchange. This necessary disruption is part of the ongoing construction of the upgraded N3/M13 Paradise Valley interchange, aimed at alleviating long-term traffic congestion in the region, SANRAL said.

Jason Lowe, SANRAL’s Eastern Region Geometrics Specialist Engineer, said, “Construction continues on the upgraded M13 Paradise Valley Off Ramps. This closure is part of the ongoing progress in the upgrade of the N3 between Westville and Paradise Valley.” As the construction progresses, SANRAL urges the public to remain patient and co-operative, recognising the implications for regular traffic flow.

The closures are scheduled as follows:

• Closure 1: From 20:00, Friday 5 June to 04:30, Saturday 6 June 2026. Traffic will be diverted via the N3 interchange offramp (exit 17 - M13 Paradise Valley) onto the M13 during this period.
• Closure 2: From 20:00, Saturday 6 June to 04:30, Sunday 7 June 2026. Traffic will again be diverted via the aforementioned route.
• Closure 3: From 20:00, Sunday 7 June to 04:30, Monday 8 June 2026. Traffic diversions will continue as previously outlined.

All road users are advised to plan ahead, anticipating longer journey times. Motorists are encouraged to start their journeys earlier than usual where possible. SANRAL has also provided full traffic accommodation plans to ensure the safety of both road users and the construction teams, Lowe said.

Truck drivers and heavy vehicles are recommended to postpone trips during these periods, or use alternative routes via the M7 or M19 to mitigate delays. Public transport providers must inform their drivers of the closures and any impact on commuter services.

The specific locations for the N3 westbound closures are:

• N3 West Bound will be fully closed at the M13 Interchange (exit 17 - M13 Paradise Valley).
• Traffic will be diverted off the N3 via the M13 Paradise Valley offramp, with options to rejoin the N3 at the M7 interchange on-ramp or to continue on the M13 towards Key Ridge.

Lowe urged all road users to heed advance warning signs and adhere to speed limits, which will be reduced in the construction zones to prioritise safety. “Compliance with these measures is essential for ensuring the safety of construction workers and motorists alike,” he added.
