Motorists travelling between Paarl and Worcester on the N1 national road should expect intermittent closures of the Huguenot Toll Road as extreme weather conditions bring dangerous gale force winds to the area.
The South African National Roads Agency (SANRAL) announced on Wednesday that the route may be partially closed to certain vehicle types when wind speeds reach hazardous levels. The restrictions come as cut-off low pressure systems sweep across the Western Cape.
Hugo’s viaduct, located just west of the Huguenot Tunnel entrance, has proven particularly vulnerable to extreme wind gusts. The structure sits in a mountain valley where wind speeds can reach levels capable of overturning trucks and smaller vehicles towing trailers or caravans. Previous incidents have seen vehicles blown over in similar conditions.
SANRAL monitors wind speeds around the clock using specialised instruments. When gusts continuously exceed predetermined safety thresholds, the toll road is closed to larger goods vehicles (Class 2 to 4) carrying light loads, as well as light motor vehicles (Class 1) towing high-sided trailers or caravans. These vehicles face the greatest risk of being blown over.
The road reopens to all traffic once wind speeds drop to safe levels, with conditions assessed in real time.
Drivers affected by closures can use the Du Toitskloof pass (R101) as an alternative route over the mountain range. This represents the shortest detour available.
The roads agency has announced plans to construct wind barriers along the viaduct to reduce the impact of strong gusts on vehicles in future.
Real time updates on road conditions are available through SANRAL’s Western Cape Freeway Management System Twitter account @CapeTownFreeway or via the I-Traffic website at https://www.i-traffic.co.za/. Variable message signs in the tunnel also display current access status.
SANRAL says road user safety remains its primary concern during severe weather events.
