"All motorists are urged to exercise caution at all times during this rainy weather and floods," Brigadier Marinda Mills said.

"Motorists should keep a safe following distance as the surface is slippery and wet almost everywhere. They should travel with their lights on to improve visibility and adhere to the legal speed limits."

They were further warned of the extra presence of trucks on routes between Grahamstown and Fort Beaufort.

After the closure of the two main roads between East London and Port Elizabeth on Monday, the R72 was reopened for light motor vehicles. It was still closed to trucks.

Heavy vehicles leaving East London for Port Elizabeth were being redirected to the N2 via Mount Coke (R345) or via Amalinda (N2) to King William's Town.

All heavy motor vehicles leaving King William's town for Port Elizabeth were being diverted onto the R63 towards Bedford and left onto the N10 to rejoin the N2.

From Grahamstown to PE traffic was being diverted towards Kenton-on-Sea and rejoining the R72 towards Alexandria. Heavy vehicles were being diverted onto the R350 past Riebeek East on to Bedford to join the N10 near Cookhouse.
