Drivers on the M25 in Surrey are dealing with miles of tailbacks after “unprecedented” closures got here into pressure.
A five-mile stretch alongside each carriageways between junctions 10 and 11 was closed at 21:00 GMT Friday and can stay shut till 06:00 on Monday.
Congestion is growing on the detour route, with drivers instructed to not “attempt to be intelligent” and search out alternate options.
