The strong winds have caused the A282 southbound QEII Bridge to close today (December 7).
It is not clear whether the bridge will reopen today yet.
All traffic wishing to travel southbound/clockwise on the M25 is diverted through the east bore tunnel.
Northbound traffic must use only the west-bore Dartford Tunnel, which has a height limit of 4.8m (15’9″).
Vehicles taller than 4.8m (15’9″) must take an alternative route via the clockwise M25.
Drivers have been warned to allow extra journey time and plan ahead.
Drivers may wish to take an alternative route or even delay their journey.
A statement on the National Highways website says: “The A282 southbound QEII Bridge at the Dartford Crossing is closed due to strong winds associated with Storm Darragh.
“All traffic wishing to travel southbound/clockwise on the M25 is being diverted through the east bore tunnel.
“Northbound crossing traffic is being confined to using the west bore Dartford tunnel only with a height restriction of 4’8m (15’9″).
“Vehicles over this height will have to seek an alternative route via the clockwise M25.
“If this closure impacts on your planned route, please allow extra journey time.
“Plan ahead, you may wish to re-route or even delay your journey.”
