Drivers are facing diversions after the closure of a main road in North Yorkshire.
Officials shut the Kex Gill stretch of the A59 that links Harrogate with Skipton following safety concerns after several days of torrential rain.
They fear a landslip could happen on the road, which has encountered problems in the past, meaning motorists are having to find an alternative route.
North Yorkshire County Council says it needs to undertake more thorough ground checks before the road can be re-opened.
The surrounding hillside has been subject to substantial movements with cracks appearing on the escarpment, according to the local authority.
Five years ago authorities shut the road for over a month while work was undertaken to fortify the bank.
The route became one of the star locations during the second day of the Tour de France two years ago.
With massive audiences watching cyclists pass through, it was re-christened the Cote de Blubberhouses after a nearby village.
County councillor Don Mackenzie, North Yorkshire's executive member for highways, has apologised to road users for any disruption caused.
He says that road safety remains the authority's main concern, adding that plans are in place to stabilise the slope.
