High winds mean the A66 is closed to high sided vehicles between the A685 junction in Brough and the A67 junction in Bowes.
Two key Cumbrian roads could be expanded under government plans to invest an extra £15 million in the country's road network.
A study looking at the case for turning both the A66 and A69 into dual carriageways will be carried out.
The study for the two trans-Pennine routes is one of nine schemes for the north west.
Police are launching an operation to improve driving and safety standards on the A66 east of Penrith to the county boundary.
The operation, codenamed Natterjack, aims to make this section of the A66 much safer by encouraging compliance with traffic laws by observation and enforcement.
Operation Natterjack focuses on motoring offences such as lack of a concentration by using a mobile phone at the wheel.
Inspector Phil Davidson, of the Operational Support Unit, said:
“It only takes a slight lapse in concentration to be involved in a serious and potentially fatal road traffic collision. We still see motorists behaving recklessly on the county’s roads using mobile devices whilst at the wheel. This behaviour produces an additional risk on a road where the risk factors are already high, leading to an increase in the number of collisions.
More precipitating factors, like a lack of concentration, leads to more collisions and it is important that through enforcement we stamp this out.

A lorry driver who caused the deaths of two soldiers in a crash on the A66 has been jailed for 18 months.
Private James Austin and Lance Sergeant David Gartland were on their way back to Catterick Garrison after a training exercise when they died in September 2011.
The soldiers' Land Rover crashed and was then hit by Colin Pattison's HGV near Stainmore in Cumbria.
Hannah McNulty reports.
A lorry driver has been jailed for 18 months for causing the deaths of two soldiers in a crash on the A66 in Cumbria.
Colin Pattison's HGV ran into the back of an army landrover on the A66 at Stainmore two years ago.
Private James Austin and Lance Sergeant David Gartland, who were returning to Catterick Garrison following an training exercise at Warcop died at the scene.
Their landrover had already hit a broken down lorry that was spewing thick smoke across the carriageway when it was hit from behind by Colin Pattison's fully laden wagon.
He had driven blindly into the smoke at around 30 miles an hour, the prosecution say he should've slowed down more.
53-year-old Pattison, from Goole in Yorkshire, was cleared of causing death by dangerous driving but found guilty of causing death by careless driving following a trial at Carlisle Crown Court last month.
He has also been banned from driving for six years.
