The Prince of Wales bridge and parts of the M4 around Bristol will be targetted by fuel protesters today, said police.
Motorists may experience much longer travel times over the Bridge and between the Almonsbury Interchange and M32 Bristol link road as well as possible slow moving traffic over the Portbury M5 bridge.
The protests are planned over soaring petrol and diesel prices in recent weeks and last week the RAC said the average cost of filling a family car was more than £100.
Fuel prices have increased sharply because the price for crude oil, which is used to make petrol and diesel, has gone up. Crude oil was cheaper at the beginning of the Covid pandemic, because many businesses temporarily closed and demand for energy collapsed.
Now it has risen with demand and the Ukraine War restricting supplies of oil from Russia along with a chnage in exchange prices as oil is bought in USD.
Yesterday, the M4 around Newport was closed after separate incidents which resulted in motorists being stuck for hours with diversions implemented for traffic heading east or west, while another crash at Cardiff Gate resulted in a closure for several hours.
