Recovery work is underway with disruption on local roads and rail services.
Coldhams Lane in Cambridge has been shut since Monday 11 December 2023 after a crash involving a lorry and a car at the Sainsburys roundabout.
The road has been shut to traffic which has left long delays through Cambridge and Cherry Hinton.
Drivers are being urged to find an alternative route.
Rail services have also been disrupted with no trains able to run between Cambridge and Newmarket.
