CAPE TOWN - Motorists trying to drive from Cape Town to Johannesburg on the N1 are stuck.
The highway just north of Beaufort West has been completely closed to traffic due to heavy snow.
Extreme weather has resulted in road closures across the Western, Eastern and Southern Cape.
The Road Traffic Management Corporation (RTMC)’s Ashref Ismail said, “Unfortunately there are no alternative routes. People will have to delay their trip. Those who find themselves approaching the area will have to turn back.”
Western Cape Traffic Chief Kenny Africa said officials are coordinating efforts to get motorists moving, but roads will remain closed.
He said motorists travelling from Kimberly through Victoria West cannot use the road.
Drivers using the road between Victoria West and Three Sisters are also affected.
The South African Weather Service said conditions should start easing later on Saturday.
Forecaster William Msimanga said, “We are still expecting very cold conditions to dominate the interior of the Western Cape, with possible snowfall mainly in parts of Beaufort West. Tomorrow [Sunday], we are not expecting any snow.”
In the Eden District Municipality, motorists been asked to avoid speeding on the roads.
Officials said the Swartberg Pass between Oudsthoorn and Prince Albert remains closed to traffic as a result.
