Two separate collisions are blocking the A14 in Cambridgeshire and the A1 to the north of Peterborough this morning, Tuesday January 24.
A crash involving a lorry and three cars is blocking one lane of the A14 eastbound at Mill Road near Fenstanton.
There are long delays back to the A14 Spur and Brampton Hut.
A collision has also partially blocked the A1 southbound at the A606 junction at Stamford.
Queues are backing up towards Stretton.
Further afield, the A10 in Cambridgeshire is also closed after a lorry overturned spilling its load of potatoes across the carriageway, closing the road in both directions.
It is closed between Stretham and Chittering.
