UPDATE, 3.37pm: North Yorkshire Police say the south-bound carriageway of the A1 has fully re-opened, while the north-bound carriageway has re-opened apart from one lane.
FREEZING temperatures have continued to cause travel chaos in North Yorkshire.
A 25-mile (40km) long section of the A1 northbound was shut this morning (Monday) between Allerton Park, near Knaresborough, and the Catterick area after a number of collisions.
A police spokesman said: “Traffic conditions on the A1 northbound from Dishforth and all the way to Leeming and beyond are treacherous.
“There have been a series of accidents which have resulted in the A1 northbound being shut while emergency services clear the scene.”
He said it was not known how long the clear-up operation would take.
North Yorkshire Fire Service said the multiple incidents started at about 2.15am and advised motorists not to travel on the A1 until further notice from the police.
The Highways Agency said the A1 at Catterick was closed southbound between the A6136 and A684, while the A1(M) in North Yorkshire was closed northbound between junctions J47 and the A6136.
